Description

本発明は、管状部材と金属管などとの接続部に、ストラップバンドを巻いて一定の締付け力で巻締める接続用ストラップバンド装置に係り、とりわけ螺子棒を回転操作可能に配設するハウジングを有する接続用ストラップバンド装置に関する。 The present invention relates to a strap band device for connection in which a strap band is wound around a connection portion between a tubular member and a metal tube or the like and wound with a fixed tightening force, and in particular, has a housing in which a screw rod is rotatably arranged. The present invention relates to a strap band device for connection.

ストラップバンドの被締結物である接続用のホースは、近年では液冷媒を圧送する車両の冷暖房用や特に高温・高圧に晒されるターボ系配管に使われるため、ホースには格段に高い耐久性が要求されている。
ホースの機械的強度を上げるため、ホースのゴム硬度を高くしたり、ホースに埋設された補強糸を増やしたり、ストラップバンドを樹脂ホースと一体化させた接着複合化構造にするなどの対策を施している。接着複合化構造のホースは、通常のゴム製ホースと異なり、ホースに高い締付け力が必要となり、安定した締付け状態を確保する方策が模索されている。 In recent years, the hose for connection, which is the strap band to be fastened, is used for air conditioning of vehicles that pump liquid refrigerant and especially for turbo piping exposed to high temperature and pressure, so the hose has a much higher durability. Is required.
In order to increase the mechanical strength of the hose, measures such as increasing the rubber hardness of the hose, increasing the number of reinforcing threads embedded in the hose, and adopting an adhesive composite structure in which the strap band is integrated with the resin hose are taken. ing. Unlike a normal rubber hose, the hose with an adhesive composite structure requires a high tightening force on the hose, and a method for ensuring a stable tightening state is being sought.

この種のストラップバンドの一般的な構造は、バンドの他端部に多数のスリット歯からなる歯列部を設け、ハウジングを有する一端部と摺接可能に重ね合わせるものである。ホースへの取付け時には、ハウジング内の螺子を歯列部のスリット歯に係合させ、回転操作することで、バンドの他端部が一端部を摺動してホースを巻き締める。 A general structure of this type of strap band is such that a tooth row portion made up of a large number of slit teeth is provided at the other end portion of the band and overlapped with one end portion having a housing so as to be slidable. At the time of attachment to the hose, the screw in the housing is engaged with the slit teeth of the dentition portion and rotated, whereby the other end portion of the band slides on one end portion and the hose is wound up.

ストラップバンド装置の具体例として、特許文献１〜３にそれぞれホースクランプ、ホースクリップおよび接続用クランプ装置が開示されている。
特許文献１〜３では、いずれも格納部としてのハウジング内にウォーム螺子を歯列部に噛合させて回転操作可能に配設し、歯列部に対するウォーム螺子の締付けトルクにより被締結物を巻き締める構造である。 As specific examples of the strap band device, Patent Documents 1 to 3 disclose a hose clamp, a hose clip, and a connection clamp device, respectively.
In each of Patent Documents 1 to 3, a worm screw is meshed with a tooth row portion in a housing as a storage portion so as to be rotatable, and the object to be fastened is tightened by tightening torque of the worm screw with respect to the tooth row portion. Structure.

また、特許文献４では、ストラップバンドの他端部側に、ストッパを取付け、螺子によるストラップバンドの締付け終了時に、ハウジングの一端部をストッパに当接させて、一端部側に対する他端部側の摺動量を規制している。
特許文献５では、ハウジングを金属板の絞り加工により加工硬化させた有底枠体として形成し、底部を他端部側にかしめなどの取付手段で固定している。 In Patent Document 4, a stopper is attached to the other end portion side of the strap band, and at the end of tightening of the strap band by the screw, one end portion of the housing is brought into contact with the stopper, The sliding amount is regulated.
In Patent Document 5, the housing is formed as a bottomed frame body that is work-hardened by drawing a metal plate, and the bottom portion is fixed to the other end side by attachment means such as caulking.

接続用クランプ装置では、品質維持の観点からストラップバンドによる締付け力の管理を行う必要があるが、特許文献１〜３のいずれも締付け力を一定に保つ品質管理を行う手段を備えていないため、被締結部に対する締付け力の点で製品にばらつきが生じ易く、製品の品質を保証するうえでの支障となる虞がある。
また、ウォーム螺子に大きな締付けトルクを適用した場合、特許文献１〜３のいずれでも、バンドが巻締め力により縮径する過程で、ウォーム螺子が歯列部を強く摺接し、ハウジングが大きく捻られることにより捩じれ変形が生じ、梁辺部と螺旋歯との噛合状態が悪化し、バンドの締付けが弛み、被締結物に対するバンドの締付け力が損なわれる虞がある。 In the connection clamping device, it is necessary to manage the tightening force by the strap band from the viewpoint of quality maintenance, but none of Patent Documents 1 to 3 includes a means for performing quality control to keep the tightening force constant. The product tends to vary in terms of the tightening force with respect to the fastened part, which may hinder the quality of the product.
Further, when a large tightening torque is applied to the worm screw, in any of Patent Documents 1 to 3, the worm screw strongly slides on the dentition portion and the housing is largely twisted in the process of reducing the diameter of the band by the tightening force. As a result, torsional deformation occurs, and the meshing state between the beam side portion and the helical teeth deteriorates, the band tightening is loosened, and the band tightening force against the object to be fastened may be impaired.

特許文献４では、ストッパを設けてストラップバンドの他端部側の摺動量を一定に規制することにより、被締結部に対するストラップバンドによる締付け力を一定に保つ品質管理を可能にしている。
特許文献５では、ハウジングとしての有底枠体は加工硬化を受けて剛性が高いので、螺子棒の回転操作時に、螺子棒に許容トルク以上の締付けトルクを加えてしまっても、ハウジングが捩じれ力に耐えられる強度を付与してハウジングの堅牢化を図っている。 In Patent Document 4, a stopper is provided to restrict the sliding amount on the other end side of the strap band to a constant level, thereby enabling quality control to keep the tightening force of the strap band against the fastened portion constant.
In Patent Document 5, since the bottomed frame as a housing is hardened due to work hardening, even if a tightening torque higher than the allowable torque is applied to the screw rod during the rotation operation of the screw rod, the housing is twisted. The housing is made strong by giving it the strength to withstand.

本発明は上記事情に鑑みてなされたもので、その目的は、ストッパを設けて被締結部に対するストラップバンドによる締付け力を一定に保つ品質管理を可能するとともに、ハウジングの剛性が高く、螺子棒の回転操作時に、許容トルク以上の締付けトルクを加えてしまっても、ハウジングが捩じれ力に耐えられる強度となり、しかも、ストラップバンドの締付け終了時にハウジングはストッパに面接触状態で均等に当接し、ストッパによるハウジングの位置規制の安定化を図る接続用ストラップバンド装置を提供することにある。 The present invention has been made in view of the above circumstances, and its purpose is to provide a stopper to provide quality control that keeps the fastening force of the strap band to the fastened portion constant, and the housing has high rigidity, and the screw rod has a high rigidity. Even if a tightening torque higher than the allowable torque is applied during the rotation operation, the housing will be strong enough to withstand the twisting force, and when the strap band has been tightened, the housing will abut against the stopper evenly in surface contact. It is an object of the present invention to provide a connecting strap band device that stabilizes the positional regulation of a housing.

（請求項１について）
ストラップバンドは、一端部側と該一端部側の外側に重なるように曲げられた他端部側とから成る。ハウジングは、ストラップバンドの一端部側に取り付けられている。螺子棒は、ハウジング内に回転操作可能に配設されている。複数列に形成されたスリットは、ストラップバンドの他端部側に設けられている。螺子棒の回転操作に伴い、螺子棒が螺旋歯をスリットに噛み合わせることにより、ストラップバンドの他端部側が一端部側に対して相対的に摺動して、ストラップバンドが縮径方向に変形して被締結物を締付ける。
ハウジングは、それぞれ平坦な辺面部を有する底部と枠部とから成り、底部をストラップバンドの一端部側に固定した上面開口型の有底枠体として構成されている。
ストラップバンドの締付け時、枠部を成す辺面部の一つが面接触状態で当接して、一端部側に対する他端部側の摺動変位を規制する当接辺部を有するストッパを備えている。ストッパは、当接辺部に形成されて他端部側の内面に位置する板辺部を有し、ストラップバンドの締付け過程で、一端部側が板辺部を常に覆った状態で摺動変位する寸法関係を有する。 (About claim 1)
The strap band includes one end side and the other end side bent so as to overlap the outer side of the one end side. The housing is attached to one end of the strap band. The screw rod is disposed in the housing so as to be rotatable. The slits formed in a plurality of rows are provided on the other end side of the strap band. As the screw rod rotates, the screw rod meshes the helical teeth with the slit, so that the other end of the strap band slides relative to the one end, and the strap band deforms in the direction of diameter reduction. And tighten the object to be fastened.
The housing includes a bottom portion and a frame portion each having a flat side surface portion, and is configured as a top-opening bottomed frame body in which the bottom portion is fixed to one end side of the strap band.
When the strap band is tightened, one of the side surface portions constituting the frame portion abuts in a surface contact state, and a stopper having a contact side portion for restricting sliding displacement on the other end side with respect to the one end side is provided. The stopper has a plate side portion formed on the contact side portion and positioned on the inner surface on the other end side, and is slid and displaced in a state where the one end side always covers the plate side portion in the tightening process of the strap band. Has a dimensional relationship.

請求項１では、ストッパを設けてストラップバンドの他端部側の摺動変位を一定に規制することにより、被締結部に対するストラップバンドによる締付け力を一定に保つ品質管理を可能にする。この際、ハウジングの平坦な辺部をストッパの当接辺部に面接触状態で当接させているので、ハウジングのストッパに対する当接状態が偏りのない均等分布となり、ストッパによるハウジングの位置規制を安定化することができる。
また、被締結部への締結後、使用などに伴ってストッパとハウジングとの間に隙間を目視した場合、螺子棒の回転操作によりハウジングをストッパに当接するまで螺進させて品質管理の完璧化を図ることができる。
また、ストッパについては、ストラップバンドの締付け過程で、一端部側が板辺部を常に覆った状態で摺動変位する寸法関係になっている。このため、ストラップバンドの締付け過程で、板辺部が直に被締結物に押し当たることがなくなり、被締結物に対する板辺部の食い込みを防ぐことができる。 According to the first aspect of the present invention, the stopper is provided to restrict the sliding displacement on the other end side of the strap band to a constant level, thereby enabling quality control to keep the tightening force of the strap band to the fastened portion constant. At this time, since the flat side portion of the housing is brought into contact with the contact side portion of the stopper in a surface contact state, the contact state with respect to the stopper of the housing has an even distribution, and the position control of the housing by the stopper is restricted. Can be stabilized.
In addition, when the gap between the stopper and the housing is visually observed during use after fastening to the fastened part, the housing is screwed until it comes into contact with the stopper by rotating the screw rod, and quality control is perfected. Can be achieved.
Further, the stopper has a dimensional relationship in which the one end portion side slides and displaces in a state where the side of the plate is always covered during the strap band tightening process. For this reason, in the process of tightening the strap band, the plate side portion is not directly pressed against the object to be fastened, and it is possible to prevent the plate side portion from biting into the object to be fastened.

（請求項２について）
請求項２が請求項１と異なるところは、ストッパのストラップバンドの摺動方向の左右側部には、他端部側の内側に重なる一端部側の左右側端部に当接しながら摺動可能で、一端部側を他端部側に揃わせるように位置規制する案内辺部を設けたことである。
これにより、他端部側が一端部側と上下に対応する状態で重なり合って揃うように位置規制され、螺子棒によるストラップバンドの締付け時などに他端部側が一端部側に対して左側や右側にはみ出ず、両者の間で位置ずれを生じることがない。 (About claim 2)
The second aspect differs from the first aspect in that the strap band of the stopper is slidable while being in contact with the left and right end portions on the one end side overlapping the inner side on the other end side on the left and right side portions in the sliding direction. Thus, there is provided a guide side portion for regulating the position so that the one end side is aligned with the other end side.
As a result, the other end side is positioned so that the other end side overlaps and aligns with the one end side, and the other end side is positioned on the left or right side of the one end side when the strap band is tightened with a screw rod. It does not protrude and no positional shift occurs between the two.

（請求項３について）
請求項３が請求項１と異なるところは、当接辺部が、ストラップバンドの他端部側の摺動方向に直交する左右側部から一体的に延出成形して他端部側に重なるように折り曲げることによりストッパを構成したことである。
このため、ストッパを別部材として加工や組付けをする必要がなくなり、とりわけ自動車などの部品として多量生産する場合にコスト的に有利である。 (Claim 3)
The third aspect differs from the first aspect in that the contact side portion is integrally formed by extending from the left and right side portions orthogonal to the sliding direction on the other end portion side of the strap band and overlaps the other end portion side. In this way, the stopper is configured by bending in such a manner.
For this reason, it is not necessary to process or assemble the stopper as a separate member, which is advantageous in terms of cost especially when mass-produced as parts such as automobiles.

（請求項４について）
請求項４が請求項１と異なるところは、他端部側に、スリット（梁辺部）と螺子棒の螺旋歯とが係合する領域に相当する大きさの制止穴部を形成するとともに、制止穴部の外周縁部に凸状に突出するリブ部を設けたことである。
螺子棒によるストラップバンドの締付け終了時に、螺旋歯がスリットと係合する部分だけ制止穴部に嵌合することで、制止穴部がハウジングに対するストッパとして一端部側に対する他端部側の摺動変位を規制する。 (About claim 4)
The difference between claim 4 and claim 1 is that, on the other end side, a stop hole portion having a size corresponding to a region where the slit (beam side portion) and the spiral tooth of the screw rod engage is formed. A rib portion protruding in a convex shape is provided on the outer peripheral edge portion of the stop hole portion.
At the end of tightening of the strap band by the screw rod, only the portion where the spiral teeth engage with the slit is fitted into the stop hole, so that the stop hole serves as a stopper for the housing and the sliding displacement on the other end side with respect to the one end side To regulate.

請求項４では、螺旋歯がスリットと係合する部分だけ制止穴部に嵌合することで、スリットに対する螺旋歯の係合が失われる。これにより、螺子棒が操作時に制止穴部で空回りして螺子棒の回転操作を無効化し、ハウジングに対するストッパとして一端部側に対する他端部側の摺動変位を規制する。このため、他端部側に制止穴部を形成するといった簡素な構造でストッパとしての機能を実現できてコスト的に有利である。
また、制止穴部の外周縁部に設けたリブ部により、制止穴部の外周縁部が補強されるため、螺旋歯が制止穴部に嵌合した際、制止穴部に対する螺旋歯の嵌合状態が強固になる。 According to the fourth aspect of the present invention, the engagement of the helical tooth with the slit is lost by fitting only the portion where the helical tooth engages with the slit into the stop hole. As a result, the screw rod idles in the stop hole portion during operation, invalidates the rotation operation of the screw rod, and restricts the sliding displacement on the other end side relative to the one end side as a stopper for the housing. For this reason, the function as a stopper can be realized with a simple structure in which a stop hole is formed on the other end side, which is advantageous in terms of cost.
In addition, since the outer peripheral edge of the stop hole is reinforced by the rib provided on the outer peripheral edge of the stop hole, when the helical tooth is fitted into the stop hole, the helical tooth is fitted to the stop hole. The state becomes solid.

（請求項５について）
ストラップバンドの締め付けに伴い、ストッパの当接辺部が支軸の先端のテーパに沿って摺接移動して先端と他端部側の表面との間に挟持される。このため、当接辺部、支軸の先端および他端部側とが強固に結合し、ハウジング、ストッパおよび他端部側が一体化して安定した堅牢な構造体となる。 (Claim 5)
As the strap band is tightened, the abutting side portion of the stopper is slidably moved along the taper at the tip of the support shaft and is sandwiched between the tip and the surface on the other end side. For this reason, the contact side portion, the tip end of the support shaft, and the other end portion side are firmly coupled, and the housing, the stopper, and the other end portion side are integrated to form a stable and robust structure.

（請求項６について）
ハウジングとしての有底枠体の枠部の左右には、ストラップバンドの幅方向に沿って形成され、ストラップバンドの一端部側を挿通させて底部の内面に当接させるための第１差込孔部および第２差込孔部が設けられ、底部を一端部側にかしめることにより固定している。 (About claim 6)
A first insertion hole formed along the width direction of the strap band on the left and right sides of the frame portion of the bottomed frame as a housing, for allowing one end portion side of the strap band to be inserted into contact with the inner surface of the bottom portion And a second insertion hole are fixed by caulking the bottom toward one end.

請求項６では、ストラップバンドをハウジングに組み付ける時、ストラップバンドの一端部側を第１差込孔部および第２差込孔部に挿通させるという簡単な操作で、かつ迅速にストラップバンドをハウジングに組み付けることができて組付性が改善し、ひいては生産性の向上に寄与する。 According to the sixth aspect of the present invention, when the strap band is assembled to the housing, the strap band can be quickly and easily inserted into the housing by inserting one end of the strap band into the first insertion hole and the second insertion hole. Assembling is improved and assemblability is improved, which contributes to productivity.

とりわけ、かしめにより有底枠体の底部をストラップバンドの一端部側に固定しているので、コスト的に有利であるとともに、溶接や締付けボルトなどを用いて固定する場合と異なり、ハウジングの迅速な組付けに資する。
この場合、一端部側を底部の内面に当接させているので、一端部側と底部との接触面積が大きくなり、一端部側に対する底部の固定状態が強固になる。 In particular, the bottom of the bottomed frame is fixed to one end of the strap band by caulking, which is advantageous in terms of cost, and unlike the case where it is fixed using welding, tightening bolts, etc. Contribute to assembly.
In this case, since the one end portion side is in contact with the inner surface of the bottom portion, the contact area between the one end portion side and the bottom portion is increased, and the fixed state of the bottom portion with respect to the one end portion side is strengthened.

（請求項７について）
ストラップバンドにおける一端部側で底部の内側に重なる部分は、径方向に沿って外側に膨出して底部を収容する張出部を形成し、底部の外側面がストラップバンドの内側面と面一となるようにしている。 (About claim 7)
The portion of the strap band that overlaps the inside of the bottom portion on one end side bulges outward along the radial direction to form a protruding portion that accommodates the bottom portion, and the outer surface of the bottom portion is flush with the inner surface of the strap band. It is trying to become.

請求項７では、一端部側で底部に対応する部分に張出部を形成しながらも、底部の外側面がストラップバンドの内側面と面一のため、被締結物に対するストラップバンドの締付け力が張出部で低下せず、一方側に偏ることなく被締結物の全面に均等に作用する利点がある。 According to the seventh aspect of the present invention, while the protruding portion is formed in the portion corresponding to the bottom portion at the one end portion side, the outer surface of the bottom portion is flush with the inner surface of the strap band, so that the strap band is tightened against the object to be fastened. There is an advantage that it does not decrease at the overhanging portion and acts evenly on the entire surface of the object to be fastened without being biased to one side.

（請求項８について）
螺子棒は、螺旋歯のねじ山が断面台形状のプロフィールを有する台形螺子である。
請求項８では、螺子棒の螺旋歯は歯厚が大きくて強度の高い歯底近傍で歯列部のスリットに噛み合う。 (About claim 8)
The screw rod is a trapezoidal screw in which the thread of the helical tooth has a trapezoidal profile.
According to an eighth aspect of the present invention, the helical teeth of the screw rod mesh with the slits of the dentition portion in the vicinity of the tooth root having a large tooth thickness and high strength.

すなわち、請求項８では、スリットに対して螺旋歯が大きな面積で噛み合い、スリットに対する螺旋歯の噛み合いが安定する。これと同時に、スリットに対する螺旋歯の噛合い箇所が増加し、螺子棒の回転操作時に、スリットに対する螺旋歯の摺接力が大きくなり、螺子棒の回転操作に伴い、ストラップバンドの他端部側に対する引張力を強化することができる。 That is, in claim 8, the helical teeth mesh with the slit in a large area, and the meshing of the helical teeth with the slit is stabilized. At the same time, the number of meshed portions of the spiral teeth with respect to the slit increases, and the sliding contact force of the spiral teeth with respect to the slit increases during the rotation of the screw rod. The tensile force can be strengthened.

（請求項９について）
ストラップバンドの幅方向に沿う横断面は、外方に向けて弓状に湾曲する形状で、中央の凸曲条部と左右端の跳ね部から成り、被締結物の締付け時、凸曲条部が被締結物に圧接するように構成されている。 (About claim 9)
The cross section along the width direction of the strap band has a shape that curves in an arch toward the outside, and consists of a central convex curve part and right and left end bounce parts.When tightening the object to be fastened, the convex curve part Is configured to be pressed against the object to be fastened.

請求項９では、中央部の凸曲条部が被締結物に圧接するので、ストラップバンドが被締結物に対して摺動変位し易い。このため、ストラップバンドが位置変位しないまま被締結物に持続的に締め付けられる構造と異なり、被締結物に対するストラップバンドの食い込みを軽減させることができる。 According to the ninth aspect of the present invention, since the convex ridge portion at the center is pressed against the object to be fastened, the strap band is easily slidably displaced with respect to the object to be fastened. For this reason, unlike the structure in which the strap band is continuously fastened to the fastened object without being displaced, the biting of the strap band with respect to the fastened object can be reduced.

本発明の接続用ストラップバンド装置では、ストッパを設け、被締結部に対するストラップバンドによる締付け力を一定に保つ品質管理を可能するとともに、絞り加工により加工硬化させた有底枠体をハウジングとして設け、剛性が高くなったハウジングが堅牢化して捩じれ変形への耐久性を向上させた点を技術的特徴とする。 In the strap band device for connection of the present invention, a stopper is provided, and quality control that keeps the tightening force of the strap band against the fastened portion constant is possible, and a bottomed frame body that is work-hardened by drawing is provided as a housing, The technical feature is that the housing with increased rigidity has been strengthened to improve durability against torsional deformation.

〔実施例１の構成〕
本発明の実施例１に係る接続用ストラップバンド装置１を図１ないし図６を参照しながら説明する。
図１における接続用ストラップバンド装置１は、被締結物としての接続ホース２に高耐久性が要求される近年の事情に鑑み、例えば接続ホース２のゴム硬度を高くし、かつ機械的強度を上げるため、補強糸を増やすなどしている。このため、接続ホース２に大きな面圧の巻締め力を締付け力として必要とする場合に好適であり、例えば、過給機付きエンジン（図示せず）であって、空気の充填率を高めるため、圧搾空気を冷却するインタークーラーと吸気管（いずれも図示せず）とを接続する場合に適用される。 [Configuration of Example 1]
A connecting strap band device 1 according to a first embodiment of the present invention will be described with reference to FIGS.
The connection strap band device 1 in FIG. 1 takes into account the recent circumstances in which high durability is required for the connection hose 2 as a fastening object, for example, increases the rubber hardness of the connection hose 2 and increases the mechanical strength. Therefore, the reinforcement thread is increased. For this reason, it is suitable for the case where a tightening force of a large surface pressure is required for the connection hose 2 as a tightening force, for example, an engine with a supercharger (not shown) for increasing the air filling rate. This is applied when an intercooler that cools compressed air and an intake pipe (both not shown) are connected.

接続用クランプ装置１は、全体的が有端環状を成すように曲成されたストラップバンド３を備え、後述するように接続ホース２に巻き締めるようにしている。ストラップバンド３は、例えばＳＵＳ３０４系のステンレス鋼板などの弾性材により、所望の幅寸法と長さ寸法とを有する帯状に形成されている。 The connecting clamp device 1 includes a strap band 3 which is bent so as to form an end-like ring as a whole, and is wound around the connecting hose 2 as described later. The strap band 3 is formed in a band shape having a desired width and length by an elastic material such as a SUS304 stainless steel plate.

ストラップバンド３の一端部側３Ａには、筒状のハウジング４が一端部側３Ａの接線方向に沿うように取付けられている。ハウジング４は、後述する図２および図３に示すように、一枚の金属シート４Ａ（ＳＵＳ３０４）を絞り加工により加工硬化して一体に形成した矩形の底部４ａと矩形の枠部４ｂとから成る浅底の有底枠体４ｃとして構成されている。底部４ａおよび枠部４ｂはそれぞれ平坦な辺面部を有するため、有底枠体４ｃは複数の平坦な辺面部を形成した上面開口型の浅底箱状を成す。有底枠体４ｃの厚み（ｔ）は、１．０ｍｍ〜２．０ｍｍの寸法範囲内で設定され、一例として１．５ｍｍの厚み（ｔ）を採用している。 A cylindrical housing 4 is attached to the one end side 3A of the strap band 3 so as to follow the tangential direction of the one end side 3A. As shown in FIGS. 2 and 3 to be described later, the housing 4 includes a rectangular bottom portion 4a and a rectangular frame portion 4b that are integrally formed by processing and hardening a single metal sheet 4A (SUS304) by drawing. It is configured as a shallow bottomed frame 4c. Since the bottom portion 4a and the frame portion 4b each have a flat side surface portion, the bottomed frame body 4c has a shallow box shape of an upper surface opening type in which a plurality of flat side surface portions are formed. The thickness (t) of the bottomed frame 4c is set within a dimension range of 1.0 mm to 2.0 mm, and a thickness (t) of 1.5 mm is adopted as an example.

有底枠体４ｃの製作にあたっては、図２（ａ）に示すように、矩形の開口部６ａおよび小円穴６ｅ付きの開口部６ｂを左右に有する金属シート４Ａを用意し、キャビティ４Ｂを備えた矩形の金型５に設置する。この状態で、金属スライダー７を打ち下ろして金属シート４Ａに絞り加工を行い、図２（ｂ）に示すように、成形された金属シート４Ａをキャビティ４Ｂから取り出し、図３（ａ）に示すように、上周辺部の耳だれ部６ｃを研削除去することにより有底枠体４ｃを形成している。 In manufacturing the bottomed frame 4c, as shown in FIG. 2A, a metal sheet 4A having a rectangular opening 6a and an opening 6b with a small circular hole 6e on the left and right is prepared, and a cavity 4B is provided. Installed in a rectangular mold 5. In this state, the metal slider 7 is lowered and the metal sheet 4A is drawn, and the formed metal sheet 4A is taken out from the cavity 4B as shown in FIG. 2 (b), as shown in FIG. 3 (a). In addition, the bottomed frame 4c is formed by grinding and removing the ear fringe portion 6c in the upper peripheral portion.

この絞り加工過程で、枠部４ｂの開口部６ａ、６ｂは、その切込み領域が拡開する塑性変形を受けて枠部４ｂの下部に形成され、ストラップバンド３の一端部側３Ａを挿通させる細長な第１差込孔部６Ａおよび第２差込孔部６Ｂを構成する。これに伴い、小円穴６ｅは、後述する螺子棒９の軸部９ｅを当接させる差込穴６Ｃを構成する。 In this drawing process, the openings 6a and 6b of the frame 4b are formed in the lower part of the frame 4b due to plastic deformation that expands the cut region, and are inserted into the strap band 3 at one end 3A. The first insertion hole 6A and the second insertion hole 6B are configured. Accordingly, the small circular hole 6e constitutes an insertion hole 6C that abuts a shaft portion 9e of a screw rod 9 described later.

すなわち、有底枠体４ｃの一辺部には、図３（ｂ）に示すように、第１差込孔部６Ａの上部に位置する支軸孔４ｄが設けられ、有底枠体４ｃの他辺部には、第２差込孔部６Ｂの上部に位置する差込穴６Ｃを設けている。
開口部６ａおよび小円穴６ｅ付きの開口部６ｂを左右に有する金属シート４Ａを用いたが、金属シート４Ａは無孔状にしておき、絞り加工後に、切削などの機械加工手段により第１差込孔部６Ａ、第２差込孔部６Ｂおよび差込穴６Ｃを形成してもよい。 That is, as shown in FIG. 3B, a supporting shaft hole 4d located at the upper part of the first insertion hole 6A is provided on one side of the bottomed frame 4c. The side portion is provided with an insertion hole 6C located above the second insertion hole portion 6B.
Although the metal sheet 4A having the opening 6a and the opening 6b with the small circular hole 6e on the left and right is used, the metal sheet 4A is made non-porous, and after drawing, the first difference is obtained by machining means such as cutting. The insertion hole 6A, the second insertion hole 6B, and the insertion hole 6C may be formed.

ストラップバンド３の一端部側３Ａは、図３（ｂ）の二点鎖線で示すように、枠部４ｂの第１差込孔部６Ａおよび第２差込孔部６Ｂを挿通し、この状態で、底部４ａを一端部側３Ａにかしめることにより強固に固定している（図１および図３（ｂ）の符号Ｇ参照）。ストラップバンド３の一端部側３Ａの外側には、これに重なるように弧状に曲げられた他端部側３Ｂが位置している。 The one end side 3A of the strap band 3 is inserted through the first insertion hole portion 6A and the second insertion hole portion 6B of the frame portion 4b as shown by a two-dot chain line in FIG. The bottom portion 4a is firmly fixed by caulking to the one end portion side 3A (see symbol G in FIGS. 1 and 3B). On the outer side of the one end side 3A of the strap band 3, the other end side 3B bent in an arc shape so as to overlap therewith is located.

ストラップバンド３の他端部側３Ｂには、図４（ａ）に示すように、ストラップバンド３を幅方向Ｗに横切り、周方向Ｒに対して所定角θだけ傾斜する状態で周方向Ｒに沿って等間隔に並列する多数のスリット８ａが設けられている。
ストラップバンド３の幅方向Ｗに沿う横断面は、図４（ｃ）に示すように、外方に向けて弓状に湾曲する形状で、中央の凸曲条部３ｐと左右端の跳ね部３ｑから成り、接続ホース２の締付け時、凸曲条部３ｐが接続ホース２に圧接するように構成されている。 As shown in FIG. 4A, the other end side 3B of the strap band 3 crosses the strap band 3 in the width direction W and is inclined in the circumferential direction R with a predetermined angle θ with respect to the circumferential direction R. A large number of slits 8a are arranged in parallel at equal intervals.
As shown in FIG. 4 (c), the cross-section along the width direction W of the strap band 3 has a shape that is curved in an arch shape toward the outside, and has a central convex curve portion 3p and right and left end bounce portions 3q. The projecting curved portion 3p is configured to be in pressure contact with the connection hose 2 when the connection hose 2 is tightened.

螺子棒９は、螺旋軸９ｓに所定のピッチ幅で形成された螺旋歯９ａを有するウォームギアの一種であり、螺旋歯９ａは、ねじ山が断面台形状のプロフィールを有する台形螺子を構成している。螺子棒９の一端部は支軸９ｂを有し、他端部は径大な鍔部９ｃおよび鍔部９ｃに隣接する角形頭部９ｄを形成している。 The screw rod 9 is a kind of worm gear having spiral teeth 9a formed at a predetermined pitch width on the spiral shaft 9s, and the spiral teeth 9a constitute a trapezoidal screw having a thread-shaped trapezoidal profile. . One end of the screw rod 9 has a support shaft 9b, and the other end forms a large flange 9c and a rectangular head 9d adjacent to the flange 9c.

螺子棒９は、差込穴６Ｃを介してハウジング４の内部に回転操作可能に配設されている。螺子棒９の支軸９ｂを枠部４ｂの辺面部４ｓに形成した支軸孔４ｄに差込み、他端部を差込穴６Ｃの開口上縁部６ｄに係止させるとともに、鍔部９ｃを枠部４ｂの外側面に当接させている（図４（ｂ）参照）。支軸９ｂは、支軸孔４ｄから突き出た先細りテーパ状の先端９ｈを有している。
螺子棒９をハウジング４の有底枠体４ｃ内に配設して、その底部４ａを一端部側３Ａにかしめることにより、螺子棒９の螺旋歯９ａがスリット８ａに噛合い係合する。この状態で、隣接するスリット８ａ間に螺旋歯９ａが噛み合う架橋状の梁辺部１０が並列して成る歯列部８Ａを形成する。 The screw rod 9 is disposed inside the housing 4 via the insertion hole 6C so as to be rotatable. The support shaft 9b of the screw rod 9 is inserted into a support shaft hole 4d formed in the side surface portion 4s of the frame portion 4b, the other end portion is locked to the opening upper edge portion 6d of the insertion hole 6C, and the flange portion 9c is fixed to the frame. It is made to contact | abut on the outer surface of the part 4b (refer FIG.4 (b)). The support shaft 9b has a tapered end 9h that protrudes from the support shaft hole 4d.
The screw rod 9 is disposed in the bottomed frame 4c of the housing 4 and the bottom portion 4a is caulked to the one end side 3A, whereby the spiral teeth 9a of the screw rod 9 are engaged with the slits 8a. In this state, a tooth row portion 8A is formed in which bridge-like beam side portions 10 in which the spiral teeth 9a mesh with each other between the adjacent slits 8a are arranged in parallel.

ストラップバンド３における一端部側３Ａで底部４ａの内側に重なる部分は、図４（ｂ）に示すように、径方向Ｓに沿って外側に膨出して底部４ａを収容する張出部３ｍを形成している。張出部３ｍの膨出量Ｅは、底部４ａの厚みＴに等し、底部４ａの外側面４ｗがストラップバンド３の内側面３ｕと面一となるように設定している。 The portion of the strap band 3 that overlaps the inside of the bottom portion 4a on the one end side 3A forms an overhang portion 3m that bulges outward along the radial direction S and accommodates the bottom portion 4a, as shown in FIG. doing. The bulging amount E of the overhanging portion 3m is set to be equal to the thickness T of the bottom portion 4a so that the outer side surface 4w of the bottom portion 4a is flush with the inner side surface 3u of the strap band 3.

ストラップバンド３の他端部側３Ｂには、ハウジング４における枠部４ｂの辺面部のうち一つの辺面部４ｓと対向するように位置するストッパ８が設けられている（図１参照）。ストッパ８は、金属製の矩形板９０を曲成したもので、中央の本体部９０ｄと本体部９０ｄの両端部に形成した折曲部９０ａ、９０ｂと本体部９０ｄの一側端面部に立設した突辺部９０ｃとを備えている。 A stopper 8 is provided on the other end portion side 3B of the strap band 3 so as to face one side surface portion 4s of the side surface portions of the frame portion 4b in the housing 4 (see FIG. 1). The stopper 8 is formed by bending a metal rectangular plate 90. The stopper 8 is erected on one end surface portion of the main body 90d and the bent portions 90a and 90b formed at both ends of the main body 90d. And the protruding side portion 90c.

矩形板９０をストッパ８として他端部側３Ｂに取付ける際、突辺部９０ｃをストラップバンド３の下方からスリット８ａを通して梁辺部１０に係合させながら折曲部９０ａ、９０ｂを当接辺部９０ｅとして他端部側３Ｂにかしめている。この場合、折曲部９０ａ、９０ｂは、かしめに加えて溶接により他端部側３Ｂに固定してもよい。 When the rectangular plate 90 is attached to the other end side 3B as the stopper 8, the bent portions 90a and 90b are brought into contact with the projecting side portion 90c while engaging the projecting side portion 90c with the beam side portion 10 from below the strap band 3 through the slit 8a. 90e is crimped to the other end 3B. In this case, the bent portions 90a and 90b may be fixed to the other end 3B by welding in addition to caulking.

ストラップバンド３の締付け工程で螺子棒９を回転操作する際、一例として図５に示すエアインパクト・ドライバー１００を締付け専用工具として用いる。
エアインパクト・ドライバー１００には、一定の締付けトルクが設定されており、ドライバー本体１００ａ内に圧搾空気を供給することにより、引き金１００ｃを介して羽根付き伝達軸（図示せず）を回転駆動し、螺子棒９の角形頭部９ｄが嵌め込まれたレンチヘッド１００ｂを一定の締付けトルクで回転操作する。 When the screw rod 9 is rotationally operated in the tightening process of the strap band 3, an air impact driver 100 shown in FIG. 5 is used as an exclusive tightening tool as an example.
A constant tightening torque is set for the air impact driver 100. By supplying compressed air into the driver main body 100a, a transmission shaft with blades (not shown) is rotationally driven via the trigger 100c. The wrench head 100b in which the square head 9d of the screw rod 9 is fitted is rotated with a constant tightening torque.

この操作に伴い、螺子棒９が螺旋歯９ａをスリット８ａに噛み合わせることで、梁辺部１０に摺接させることにより、ストラップバンド３の他端部側３Ｂが一端部側３Ａに対して巻締まり方向に沿って相対的に摺動し、ストラップバンド３が縮径方向に変形して接続ホース２に締め付ける。 As a result of this operation, the screw rod 9 meshes the spiral teeth 9a with the slits 8a, and is brought into sliding contact with the beam side portion 10, whereby the other end side 3B of the strap band 3 is wound around the one end side 3A. Relative sliding along the tightening direction causes the strap band 3 to deform in the reduced diameter direction and fasten to the connection hose 2.

螺子棒９によるストラップバンド３の締付け（終了）時に、図６に示すように、ハウジング４における枠体の辺面部のうち一つの辺面部４ｓをストッパ８の当接辺部９０ｅの先端に面接触状態で当接させて、一端部側３Ａに対する他端部側３Ｂの摺動変位（摺動量）を規制して螺子棒９の回転操作を阻止する。 When the strap band 3 is tightened (finished) by the screw rod 9, one side surface portion 4s of the side surface portions of the frame body in the housing 4 is brought into surface contact with the tip of the contact side portion 90e of the stopper 8 as shown in FIG. In this state, the sliding displacement (sliding amount) of the other end side 3B with respect to the one end side 3A is restricted to prevent the screw rod 9 from rotating.

この過程で、図４（ｂ）に二点鎖線で示すように、ストッパ８の当接辺部９０ｅが支軸９ｂの先端９ｈのテーパに沿って締付け方向に摺接移動し、その先端９ｈと他端部側３Ｂの表面との間に挟持される。これにより、当接辺部９０ｅ、先端９ｈおよび他端部側３Ｂとが強固に結合し、ハウジング４、ストッパ８および他端部側３Ｂの三者が一体化して安定した堅牢な構造体となる。なお、図４（ｂ）では、当接辺部９０ｅの挟持状態を示すため、ストッパ８および支軸９ｂの先端９ｈを誇張して描いている。 In this process, as shown by a two-dot chain line in FIG. 4 (b), the contact side 90e of the stopper 8 slides in the tightening direction along the taper of the tip 9h of the support shaft 9b, and the tip 9h It is clamped between the surfaces of the other end side 3B. Thereby, the contact side 90e, the tip 9h, and the other end 3B are firmly coupled, and the three of the housing 4, the stopper 8, and the other end 3B are integrated to form a stable and robust structure. . In FIG. 4B, the stopper 8 and the tip end 9h of the support shaft 9b are exaggerated to show the clamped state of the abutting side portion 90e.

また、ストッパ８は、当接辺部９０ｅに形成されて他端部側３Ｂの内面に位置する矩形板９０を板辺部として有している。ストラップバンド３の締付け過程で、一端部側３Ａが矩形板９０を常に覆った状態で摺動変位する寸法関係を有している。このため、図１および図６に示すように、ストラップバンド３の締付け開始から終了まで、矩形板９０が接続ホース２に直接押し当たることがなくなり、接続ホース２に対する矩形板９０の食い込みを防ぐことができる。 Moreover, the stopper 8 has the rectangular plate 90 formed in the contact side part 90e and located in the inner surface of the other end part side 3B as a plate side part. In the tightening process of the strap band 3, there is a dimensional relationship in which the one end side 3 </ b> A slides and displaces in a state where the rectangular plate 90 is always covered. For this reason, as shown in FIGS. 1 and 6, the rectangular plate 90 is not directly pressed against the connection hose 2 from the start to the end of tightening of the strap band 3, thereby preventing the rectangular plate 90 from biting into the connection hose 2. Can do.

摺動変位の規制により、螺子棒９の回転が阻止されるので、レンチヘッド１００ｂは、エアインパクト・ドライバー１００による駆動力を受けるものの、回転付勢したまま螺子棒９を一定の締付けトルクで締付ける。この締付け時点で、操作者は、レンチヘッド１００ｂをエアインパクト・ドライバー１００と一緒に角形頭部９ｄから抜き取って螺子棒９の締付け工程を終える。 Since the rotation of the screw rod 9 is prevented by the restriction of the sliding displacement, the wrench head 100b receives the driving force from the air impact driver 100, but tightens the screw rod 9 with a constant tightening torque while being urged to rotate. . At the time of tightening, the operator pulls out the wrench head 100b together with the air impact driver 100 from the square head 9d and finishes the tightening process of the screw rod 9.

〔実施例１の効果〕
実施例１では、ストッパ８を設けてストラップバンド３の他端部側３Ｂの摺動変位を一定に規制することにより、接続ホース２に対するストラップバンド３による締付け力を一定に保つ品質管理を可能にする。この際、ハウジング４における枠部４ｂの辺面部４ｓをストッパ８の当接辺部９０ｅに面接触状態で当接させているので、ハウジング４のストッパ８に対する当接状態が偏りのない均等分布となり、ストッパ８によるハウジング４の位置規制を安定化することができる。
また、接続ホース２への締結後、使用などに伴い、ストッパ８とハウジング４との間に生じた隙間を目視した場合、螺子棒９の回転操作により、ハウジング４をストッパ８に当接するまで螺進させて品質管理の完璧化を図ることができる。 [Effect of Example 1]
In the first embodiment, the stopper 8 is provided to restrict the sliding displacement of the other end side 3B of the strap band 3 to be constant, thereby enabling quality control to keep the tightening force by the strap band 3 against the connection hose 2 constant. To do. At this time, since the side surface portion 4s of the frame portion 4b in the housing 4 is brought into contact with the contact side portion 90e of the stopper 8 in a surface contact state, the contact state of the housing 4 with respect to the stopper 8 has an even distribution. The position restriction of the housing 4 by the stopper 8 can be stabilized.
In addition, when the gap formed between the stopper 8 and the housing 4 is visually observed after being fastened to the connection hose 2, the screw is rotated until the housing 4 comes into contact with the stopper 8 by rotating the screw rod 9. To improve quality control.

ハウジング４としての有底枠体４ｃの枠部４ｂの左右には、ストラップバンド４の幅方向Ｗに沿って形成され、ストラップバンド３の一端部側３Ａを挿通させて底部４ａの内面に当接させるための第１差込孔部６Ａおよび第２差込孔部６Ｂが設けられ、底部４ａを一端部側３Ａにかしめることにより固定している。 Formed along the width direction W of the strap band 4 on the left and right sides of the frame portion 4b of the bottomed frame 4c as the housing 4, and is in contact with the inner surface of the bottom portion 4a through the one end side 3A of the strap band 3. A first insertion hole portion 6A and a second insertion hole portion 6B are provided, and are fixed by caulking the bottom portion 4a to the one end portion side 3A.

これにより、ストラップバンド３をハウジング４に組み付ける時、ストラップバンド３の一端部側３Ａを第１差込孔部６Ａおよび第２差込孔部６Ｂに挿通させるという簡単な操作で、かつ迅速にストラップバンド３をハウジング４に組み付けることができて組付性が改善し、ひいては生産性の向上に寄与する。 As a result, when the strap band 3 is assembled to the housing 4, the strap band 3 can be quickly strapped by a simple operation of inserting one end side 3A of the strap band 3 into the first insertion hole 6A and the second insertion hole 6B. The band 3 can be assembled to the housing 4 and the assemblability is improved, thereby contributing to the improvement of productivity.

かしめにより有底枠体４ｃの底部４ａをストラップバンド３の一端部側３Ａに固定しているので、コスト的に有利であるとともに、溶接や締付けボルト（図示せず）などを用いて固定する場合と異なり、ハウジング４の迅速な組付けに資する。
この場合、一端部側３Ａを底部４ａの内面に当接させているので、一端部側３Ａと底部４ａとの接触面積が大きくなり、一端部側３Ａに対する底部４ａの固定状態が強固になる。 Since the bottom portion 4a of the bottomed frame 4c is fixed to the one end side 3A of the strap band 3 by caulking, it is advantageous in terms of cost and is fixed using welding, a fastening bolt (not shown), or the like. Unlike this, it contributes to quick assembly of the housing 4.
In this case, since the one end portion side 3A is in contact with the inner surface of the bottom portion 4a, the contact area between the one end portion side 3A and the bottom portion 4a is increased, and the fixed state of the bottom portion 4a with respect to the one end portion side 3A is strengthened.

ここで、通常の取付構造として、ハウジングの底部が左辺部と右辺部との二つの部分に分かれており、左辺部と右辺部とを一端部側３Ａに折り曲げてかしめて固定する構造に言及する。
この取付構造では、螺子棒９の回転操作時に、螺子棒９に許容トルク以上の締付けトルクを加えてしまった場合、ハウジングの捩じれ力Ｋが底部４ａに伝わり、底部４ａに大きな捩じれ力Ｋが作用するため、左辺部の先端縁と右辺部の先端縁との突合せ部が捩じれて左辺部と右辺部とが歪み、一端部側３Ａに対する底部４ａの固定状態が劣化する虞がある。 Here, as a normal mounting structure, the bottom part of the housing is divided into two parts, that is, a left side part and a right side part, and the left side part and the right side part are bent and fixed to one end side 3A and fixed. .
In this mounting structure, when a tightening torque greater than the allowable torque is applied to the screw rod 9 during the rotation operation of the screw rod 9, the torsional force K of the housing is transmitted to the bottom portion 4a, and a large torsional force K acts on the bottom portion 4a. Therefore, the abutting portion between the leading edge of the left side portion and the leading edge of the right side portion is twisted, the left side portion and the right side portion are distorted, and the fixed state of the bottom portion 4a to the one end side 3A may be deteriorated.

これに対して、実施例１では、一端部側３Ａに当接する底部４ａが加工硬化を受けて強度が向上した一体物で有るので、底部４ａに大きな捩じれ力Ｋが作用しても、底部４ａが左辺部と右辺部との突合せ部を有する取付構造と異なり、底部４ａが捩じれ変形せず、一端部側３Ａに対する底部４ａの固定状態を良好に保つことができる。 On the other hand, in the first embodiment, the bottom 4a that is in contact with the one end side 3A is an integrated body that has been hardened by work hardening, so that even if a large twisting force K acts on the bottom 4a, the bottom 4a. Unlike the mounting structure having the butted portion of the left side portion and the right side portion, the bottom portion 4a is not twisted and deformed, and the fixed state of the bottom portion 4a with respect to the one end portion side 3A can be kept good.

ストラップバンド３における一端部側３Ａで底部４ａの内側に重なる部分は、径方向Ｓに沿って外側に膨出して底部４ａを収容する張出部３ｍを形成し、底部４ａの外側面４ｗがストラップバンド３の内側面３ｕと面一となるように設定している。
このため、一端部側３Ａで底部４ａに対応する部分に張出部３ｍを形成しながらも、底部４ａの外側面４ｗがストラップバンド３の内側面３ｕと面一のため、接続ホース２に対するストラップバンド３の締付け力が張出部３ｍで低下せず、一方側に偏ることなく接続ホース２の全面に均等に作用する利点がある。 The portion of the strap band 3 that overlaps the inside of the bottom portion 4a on the one end side 3A forms an overhang portion 3m that bulges outward along the radial direction S and accommodates the bottom portion 4a, and the outer surface 4w of the bottom portion 4a is the strap. The inner surface 3u of the band 3 is set to be flush with the inner surface 3u.
For this reason, while forming the overhang | projection part 3m in the part corresponding to the bottom part 4a in the one end part side 3A, since the outer side surface 4w of the bottom part 4a is flush with the inner side surface 3u of the strap band 3, it is a strap for the connection hose 2. There is an advantage that the tightening force of the band 3 does not decrease at the overhang portion 3m and acts evenly on the entire surface of the connection hose 2 without being biased to one side.

螺子棒９は、螺旋歯９ａのねじ山が断面台形状のプロフィールを有する台形螺子であるので、螺子棒９の螺旋歯９ａは歯厚が大きくて強度の高い歯底近傍で歯列部８Ａの梁辺部１０（スリット８ａ）に噛み合う。
すなわち、梁辺部１０（スリット８ａ）に対して螺旋歯９ａが大きな面積で噛み合い、梁辺部１０（スリット８ａ）に対する螺旋歯９ａの噛み合いが安定する。これと同時に、梁辺部１０（スリット８ａ）に対する螺旋歯９ａの噛合い箇所が増加し、螺子棒９の回転操作時に、梁辺部１０（スリット８ａ）に対する螺旋歯９ａの摺接力が大きくなり、螺子棒９の回転操作に伴い、ストラップバンド３の他端部側３Ｂに対する引張力を強化することができる。 The screw rod 9 is a trapezoidal screw in which the thread of the spiral tooth 9a has a trapezoidal cross-sectional profile. Therefore, the spiral tooth 9a of the screw rod 9 has a large tooth thickness and a high strength near the root of the tooth row portion 8A. It meshes with the beam side portion 10 (slit 8a).
That is, the helical teeth 9a mesh with the beam side portion 10 (slit 8a) in a large area, and the meshing of the helical teeth 9a with the beam side portion 10 (slit 8a) is stabilized. At the same time, the number of meshed portions of the spiral teeth 9a with respect to the beam side portion 10 (slit 8a) increases, and the sliding contact force of the spiral teeth 9a with respect to the beam side portion 10 (slit 8a) increases when the screw rod 9 is rotated. As the screw rod 9 is rotated, the tensile force on the other end side 3B of the strap band 3 can be strengthened.

金属シート４Ａはステンレス鋼系の金属であり、ハウジング４としての有底枠体４ｃは厚み（ｔ）を１．０ｍｍ〜２．０ｍｍの寸法範囲内に設定しているため、ハウジング４としての有底枠体４ｃは、金属シート４Ａの絞り加工により加工硬化を受け、必要な強度を保持しながらも、厚み（ｔ）が小さくて軽量になり、管理が容易で取り扱い易くなる。 The metal sheet 4A is a stainless steel metal, and the bottomed frame 4c as the housing 4 has a thickness (t) set within a dimensional range of 1.0 mm to 2.0 mm. The bottom frame 4c is work-hardened by drawing the metal sheet 4A and maintains the required strength, but the thickness (t) is small and light, and is easy to manage and easy to handle.

中央部の凸曲条部３ｐが接続ホース２に圧接するので、ストラップバンド３が接続ホース２に対して摺動変位し易い。このため、ストラップバンド３が位置変位しないまま接続ホース２に持続的に締め付けられる構造と異なり、接続ホース２に対するストラップバンド３の食い込みを軽減させることができる。 Since the central curved protrusion 3p is in pressure contact with the connection hose 2, the strap band 3 is easily slidably displaced with respect to the connection hose 2. For this reason, unlike the structure in which the strap band 3 is continuously tightened to the connection hose 2 without being displaced, the biting of the strap band 3 with respect to the connection hose 2 can be reduced.

〔実施例２の構成〕
図７（ａ）は本発明の実施例２を示す。実施例２が実施例１と異なるところは、ハウジング４としての有底枠体４ｃを楕円環状の枠部４ｆと長円盤状の底部４ｇとから成る有底枠体４ｈにより構成したことである。
有底枠体４ｈとして実施例２のように構成しても実施例１と同様な効果が得られる。 [Configuration of Example 2]
FIG. 7A shows a second embodiment of the present invention. Example 2 differs from Example 1 in that a bottomed frame 4c as a housing 4 is configured by a bottomed frame 4h composed of an elliptical annular frame 4f and an oblong bottom 4g.

図８（ａ）、（ｂ）は本発明の実施例３を示す。実施例３が実施例１と異なるところは、矩形板９０をストッパ８として他端部側３Ｂに取付ける際、突辺部９０ｃを梁辺部１０にストラップバンド３の上方から係合させながら、折曲部９０ａ、９０ｂを筒状に湾曲させて他端部側３Ｂにかしめたことである。
この場合、折曲部９０ａ、９０ｂは、左右両側に上方に膨らむ筒状の膨出部９０ｈを形成し、膨出部９０ｈの先端を当接辺部９０ｅとしている。これにより、ハウジング４の辺部４ｓに対する当接辺部９０ｅの先端の当接面積を大きくし、ハウジング４に対するストッパ８としての阻止力を効果的に発揮させることができる。 [Configuration of Example 3]
8A and 8B show Example 3 of the present invention. Example 3 differs from Example 1 in that when the rectangular plate 90 is used as the stopper 8 and attached to the other end side 3B, the protruding side part 90c is engaged with the beam side part 10 from above the strap band 3 while folding. That is, the curved portions 90a and 90b are bent in a cylindrical shape and crimped to the other end side 3B.
In this case, the bent portions 90a and 90b form a cylindrical bulged portion 90h that bulges upward on both the left and right sides, and the tip of the bulged portion 90h serves as a contact side portion 90e. Thereby, the contact area of the front-end | tip of the contact side part 90e with respect to the side part 4s of the housing 4 can be enlarged, and the blocking force as the stopper 8 with respect to the housing 4 can be exhibited effectively.

〔実施例４の構成〕
図９（ａ）−（ｃ）は本発明の実施例４を示す。実施例４が実施例１と異なるところは、ストッパ８をストラップバンド３の他端部側３Ｂに一体的に形成したことである（図９（ａ）参照）。
この場合、ストッパ８を設けるにあたっては、ストラップバンド３の摺動方向に直交する左右側部から折曲部９０ａ、９０ｂを当接辺部９０ｅとして一体的に延出成形し、図９（ｂ）に矢印Ｆで示す方向に折り曲げ、他端部側３Ｂの上面に重なるように当接させる（図９（ｃ）の二点鎖線参照）。
実施例４では、ストッパを別部材として加工や組付けをする必要がなくなり、とりわけ自動車などの部品として大量生産する場合にコスト的に有利となる。 [Configuration of Example 4]
FIGS. 9A to 9C show Example 4 of the present invention. The difference between the fourth embodiment and the first embodiment is that the stopper 8 is formed integrally with the other end 3B of the strap band 3 (see FIG. 9A).
In this case, when the stopper 8 is provided, the bent portions 90a and 90b are integrally extended and formed from the left and right side portions orthogonal to the sliding direction of the strap band 3 as shown in FIG. Is bent in the direction indicated by the arrow F and is brought into contact with the upper surface of the other end 3B (see the two-dot chain line in FIG. 9C).
In the fourth embodiment, there is no need to process and assemble the stopper as a separate member, which is advantageous in terms of cost especially when mass-produced as a part such as an automobile.

〔実施例５の構成〕
図１０は本発明の実施例５を示す。実施例５が実施例１と異なるところは、ストッパ８としての矩形板９を他端部側３Ｂの上面に溶接（例えば、スポット溶接）により固定したことである。ストッパ８に案内辺部９０ｇを形成するにあたっては、矩形板９０のストラップバンド３の摺動方向の左右側部から下方に延出する延出辺９０ｆの下端部を案内辺部９０ｇとして全体で偏平な断面門型を成すようにする。すなわち、案内辺部９０ｇは、延出辺９０ｆを一端部側３Ａの厚みに相当する長さＭｓだけ一体的に延出することで形成されている。 [Configuration of Example 5]
FIG. 10 shows a fifth embodiment of the present invention. The fifth embodiment differs from the first embodiment in that a rectangular plate 9 as the stopper 8 is fixed to the upper surface of the other end 3B by welding (for example, spot welding). When the guide side portion 90g is formed on the stopper 8, the lower end portion of the extended side 90f extending downward from the left and right side portions in the sliding direction of the strap band 3 of the rectangular plate 90 is used as a guide side portion 90g so as to be flat as a whole. Make a cross-sectional gate shape. That is, the guide side part 90g is formed by extending the extension side 90f integrally by a length Ms corresponding to the thickness of the one end part side 3A.

実施例５では、案内辺部９０ｇを設けたので、他端部側３Ｂが一端部側３Ａと上下に対応する状態で重なり合って揃うように位置規制され、螺子棒９によるストラップバンド３の締付け時などに他端部側３Ｂが一端部側３Ａに対して左側や右側にはみ出さず、両者３Ｂ、３Ａの間で位置ずれが生じることがない。 In the fifth embodiment, since the guide side part 90g is provided, the position of the other end part 3B is regulated so as to overlap and align with the one end part side 3A in the vertical direction, and when the strap band 3 is tightened by the screw rod 9, In other words, the other end side 3B does not protrude to the left side or the right side with respect to the one end side 3A, and no positional deviation occurs between the both ends 3B, 3A.

〔実施例６の構成〕
図１１および図１２（ａ）、（ｂ）は本発明の実施例６を示す。実施例６が実施例１と異なるところは、他端部側３Ｂに、スリット８ａと螺子棒９の螺旋歯９ａとが係合する領域に相当する大きさの制止穴部３ｋを形成したことである（図１１参照）。螺子棒９によるストラップバンド３の締付け終了時に、螺旋歯９ａがスリット８ａと係合する部分だけ制止穴部３ｋに嵌合することで、制止穴部３ｋがハウジング４に対するストッパ８として一端部側３Ａに対する他端部側３Ｂの摺動変位を規制する（図１２（ａ）、（ｂ）参照）。 [Configuration of Example 6]
11 and 12 (a) and 12 (b) show a sixth embodiment of the present invention. Example 6 differs from Example 1 in that the other end side 3B is formed with a stop hole 3k having a size corresponding to a region where the slit 8a and the helical tooth 9a of the screw rod 9 are engaged. Yes (see FIG. 11). At the end of the tightening of the strap band 3 by the screw rod 9, only the portion where the spiral tooth 9a engages with the slit 8a is fitted into the stop hole portion 3k, so that the stop hole portion 3k serves as the stopper 8 for the housing 4 on the one end side 3A. The sliding displacement of the other end portion side 3B with respect to is regulated (see FIGS. 12A and 12B).

実施例６では、螺旋歯９ａがスリット８ａと係合する部分だけ制止穴部３ｋに嵌合することで、スリット８ａに対する螺旋歯９ａの係合が失われる。これにより、螺子棒９が操作時に制止穴部３ｋで空回りして螺子棒９の回転操作を無効化し、ハウジング４に対するストッパ８として一端部側３Ａに対する他端部側３Ｂの摺動変位を規制する。
このため、他端部側３Ｂに制止穴部３ｋを形成するといった簡素な構造でストッパとしての機能を実現できてコスト的に有利である。 In Example 6, the engagement of the spiral teeth 9a with the slits 8a is lost by fitting only the portions where the spiral teeth 9a engage with the slits 8a into the stop holes 3k. As a result, the screw rod 9 rotates idle in the stop hole portion 3k during operation, invalidates the rotation operation of the screw rod 9, and restricts the sliding displacement of the other end portion side 3B relative to the one end portion side 3A as the stopper 8 for the housing 4. .
For this reason, the function as a stopper can be realized with a simple structure in which the stop hole portion 3k is formed on the other end side 3B, which is advantageous in terms of cost.

実施例６の変形例として、図１３（ａ）、（ｂ）に示すように、制止穴部３ｋの外周縁部１０ｍに凸状に突出するリブ部１０ｎを設けてもよい。この場合、制止穴部３ｋの外周縁部１０ｍに設けたリブ部１０ｎにより、制止穴部３ｋの外周縁部１０ｍが補強されるため、螺旋歯９ａが制止穴部３ｋに嵌合した際、制止穴部３ｋに対する螺旋歯９ａの嵌合状態が強固になる。 As a modification of the sixth embodiment, as shown in FIGS. 13A and 13B, a rib portion 10n protruding in a convex shape may be provided on the outer peripheral edge portion 10m of the stop hole portion 3k. In this case, since the outer peripheral edge portion 10m of the stop hole portion 3k is reinforced by the rib portion 10n provided on the outer peripheral edge portion 10m of the stop hole portion 3k, when the helical tooth 9a is fitted into the stop hole portion 3k, the stop portion is stopped. The fitting state of the helical tooth 9a with respect to the hole 3k is strengthened.

〔変形例〕
（ａ）上記実施例１〜６において、ハウジング４をストラップバンド３の一端部側３Ａの接線方向に沿うように取付けたが、幾何学的な正確さは必要でなく、接線方向に対する多少のずれは許容範囲であり、実用上の観点から接線方向であればよい。
（ｂ）ハウジング４の底部４ａへのかしめに代わって、各種の溶接（抵抗溶接、プロジェクション溶接、アーク溶接、ＴＩＧ溶接、プラズマ溶接）などの取付手段を用いてハウジング４の底部４ａをストラップバンド３の一端部側３Ａに固定してもよい。
（ｃ）螺子棒９については、螺旋状の軸長部を鼓状に形成し、この軸長部をストラップバンド３の周方向に沿い易くして、梁辺部１０に対して螺旋歯９ａが噛み合う歯数を増やしてもよい。 [Modification]
