As the plastic used for molding these parts, for example, polyacetal (polyoxymethylene (POM)) excellent in wear resistance and mechanical strength is preferable.

２．ヘッドバンド
図２、図３において、ヘッドバンド１０は、ともに帯状で側面視が弧状の第１のバンド部材１０１と第２のバンド部材１０２とを組み合わせて構成される。第１のバンド部材１０１及び第２のバンド部材１０２は、それぞれ長さ方向に延びる摺動孔１０３，１０４が形成される。 2. Headband In FIGS. 2 and 3, the headband 10 is configured by combining a first band member 101 and a second band member 102 that are both band-shaped and arc-shaped in side view. The first band member 101 and the second band member 102 are formed with sliding holes 103 and 104 extending in the length direction, respectively.

第１のバンド部材１０１の一端に第１係合子１０５を設け、第２のバンド部材１０２の一端に第２係合子１０６が設けられている。第１及び第２のバンド部材１０１，１０２の端部付近に設けられた抜止めの第１及び第２係合子１０５，１０６は、第１係合子１０５が第１のバンド部材１０１の外側表面に突出して形成され、また、第２係合子１０６が第２のバンド部材１０２の内側表面に突出して形成されている（図２，図３）。第１及び第２係合子１０５，１０６は、摺動孔１０３，１０４の幅よりも幅が広く形成されているため、第１及び第２係合子１０５，１０６が相手方バンド部材の摺動孔１０３，１０４に摺動自在でかつ組立て後は脱出不可に結合される。 A first engagement element 105 is provided at one end of the first band member 101, and a second engagement element 106 is provided at one end of the second band member 102. The first and second engaging members 105, 106 that are provided in the vicinity of the end portions of the first and second band members 101, 102 have the first engaging member 105 on the outer surface of the first band member 101. The second engaging element 106 is formed so as to protrude from the inner surface of the second band member 102 (FIGS. 2 and 3). Since the first and second engaging elements 105 and 106 are formed wider than the sliding holes 103 and 104, the first and second engaging elements 105 and 106 are formed in the sliding hole 103 of the counterpart band member. , 104 are slidable and are assembled so as not to escape after assembly.

ヘッドバンド１０は、第１のバンド部材１０１を第２のバンド部材１０２の内側表面（裏面）に当接し、第１係合子１０５を第２のバンド部材１０２の摺動孔１０４に下方から挿入し、また、第２係合子１０６は、第１のバンド部材１０１の摺動孔１０３に上方から挿入して両者を長さ方向に摺動自在に結合している。なお、第１及び第２のバンド部材１０１，１０２は、第１及び第２係合子１０５，１０６が相手方の摺動孔１０３，１０４内を摺動する範囲で全体の長さ調整が可能となる。そのため、耳当て装置１によれば、使用しない際にはヘッドバンド１０を縮めてコンパクトにすることができる。コンパクトに縮めた耳当て装置１は、持ち運びや収納に有利である。 In the headband 10, the first band member 101 is brought into contact with the inner surface (back surface) of the second band member 102, and the first engagement element 105 is inserted into the sliding hole 104 of the second band member 102 from below. Further, the second engaging element 106 is inserted into the sliding hole 103 of the first band member 101 from above and is slidably coupled in the longitudinal direction. The first and second band members 101 and 102 can be adjusted in overall length within a range in which the first and second engaging members 105 and 106 slide in the mating sliding holes 103 and 104. . Therefore, according to the ear pad 1, the headband 10 can be shortened to be compact when not in use. The ear pad 1 that has been compacted is advantageous for carrying and storage.

第１及び第２係合子１０５，１０６が摺動孔１０３，１０４から外れないようにするために、第１及び第２係合子１０５，１０６は、断面形状が矩形の軸部と、軸部の上端にバンド部材の長手方向に直交する方向に摺動孔１０３，１０４より長い幅を有する抜止め頭部と、を有する。 In order to prevent the first and second engaging elements 105 and 106 from being detached from the sliding holes 103 and 104, the first and second engaging elements 105 and 106 have a shaft portion having a rectangular cross-sectional shape and a shaft portion. And a retaining head having a width longer than the sliding holes 103 and 104 in a direction perpendicular to the longitudinal direction of the band member at the upper end.

第１及び第２のバンド部材１０１，１０２を組み立てるには、まず、第２のバンド部材１０２の内側表面に第１のバンド部材１０１を直交する方向に向けて当接し、第１のバンド部材１０１が有する第１係合子１０５を第２のバンド部材１０２の摺動孔１０４に挿入する。次いで、２つのバンド部材１０１，１０２を９０度回動してバンド部材を平行方向に向けると、摺動孔１０４から突出している第１係合子１０５の抜止め頭部が第２のバン
ド部材１０２の外側表面に係合状態で装着される。そして、摺動孔１０３を弾性変形させて広げて第２係合子１０６の抜け止め頭部をその間に押し込めば、組み立てできる。第２係合子１０６の抜け止め頭部の幅は摺動孔１０３の幅よりも広いので、組み立てた後は容易にはずれることは無い。 To assemble the first and second band members 101, 102, first, the first band member 101 is brought into contact with the inner surface of the second band member 102 in the direction orthogonal to the first band member 101. Is inserted into the sliding hole 104 of the second band member 102. Next, when the two band members 101 and 102 are rotated 90 degrees and the band members are oriented in the parallel direction, the retaining head portion of the first engagement element 105 protruding from the sliding hole 104 becomes the second band member 102.

軸受部４２は、Ｊ字型の曲線部の内側面であり、縦断面が円弧状の曲面で形成される。軸受部４２の曲面は、後述する第１連結片３０の回転軸部３２（図５）の外径と同じかがたつきが大きくならない程度にわずかに大きい。第２連結片４０は、軸受部４２から第２連結片４０の外側面に貫通する第１挿通孔４４を有する。 The bearing portion 42 is an inner surface of a J-shaped curved portion, and a longitudinal section is formed by an arcuate curved surface. The curved surface of the bearing portion 42 is slightly large so that the same shading as the outer diameter of the rotating shaft portion 32 (FIG. 5) of the first connecting piece 30 described later does not increase. The second connecting piece 40 has a first insertion hole 44 that penetrates from the bearing portion 42 to the outer surface of the second connecting piece 40.

第１挿通孔４４は、後述する第１連結片３０の本体３１を受け入れ可能で、かつ、第１連結片３０の回転軸部３２の長さよりも短い幅を有する。第１挿通孔４４は、軸受部４２（Ｊ字型の曲線部）に沿って内側から外側に長く形成され、第１連結片３０の本体３１が回転軸部３２を中心に回転することを許容する。第１挿通孔４４は、内側の端面に内停止面４４ａと、外側の端面に外停止面４４ｂと、を有する。内停止面４４ａは本体３１が内側に回転した際に当接し、外停止面４４ｂは本体３１が外側に回転した際に当接して、それ以上の回転を規制する。 The first insertion hole 44 can receive a main body 31 of the first connection piece 30 described later and has a width shorter than the length of the rotary shaft portion 32 of the first connection piece 30. The first insertion hole 44 is elongated from the inside to the outside along the bearing portion 42 (J-shaped curved portion), and allows the main body 31 of the first connecting piece 30 to rotate around the rotation shaft portion 32. To do. The first insertion hole 44 has an inner stop surface 44a on the inner end surface and an outer stop surface 44b on the outer end surface. The inner stop surface 44a abuts when the main body 31 rotates inward, and the outer stop surface 44b abuts when the main body 31 rotates outward to restrict further rotation.

３−２．第１連結片
図７，８，１０に示すように、第１連結片３０は、正面または背面から見て略Ｔ字状であり、帯状の本体３１と、本体３１の幅よりも長い回転軸部３２と、を有する。 3-2. First Connection Piece As shown in FIGS. 7, 8, and 10, the first connection piece 30 is substantially T-shaped when viewed from the front or the back, and has a strip-shaped main body 31 and a rotation shaft longer than the width of the main body 31. Part 32.

図９，１０に示すように第１連結片３０の本体３１は、一端が耳カップ２０に接続され、また図５〜８に示すように他端に一体形成された回転軸部３２が第２連結片４０に回転自在に保持される。 As shown in FIGS. 9 and 10, the main body 31 of the first connecting piece 30 has one end connected to the ear cup 20, and as shown in FIGS. The connecting piece 40 is rotatably held.

図５，６に示すように、本体３１は、帯状であって、内側に屈曲する。本体３１は、本体３１の他方の端部にあって幅の狭い帯状の挿入部３４と、挿入部３４から外側に突出する抜け止め部３６と、を有する。回転軸部３２は、略円柱状であり、長手方向の中央付近で本体３１の一端と接続する。 As shown in FIGS. 5 and 6, the main body 31 has a belt shape and bends inward.

The rotating shaft portion 32 has a substantially cylindrical shape and is connected to one end of the main body 31 in the vicinity of the center in the longitudinal direction.

３−３．耳カップ
図１，９，１０に示すように、耳カップ２０は、円板を緩やかに外側に湾曲させたカップ状であり、多数の貫通孔である透孔２２と、第１連結片３０が挿入される挿入孔２４と、カップ状の内側に突出するバンド係合口２５と、バンド保持ガイド２６と、を有する。 3-3. Ear Cup As shown in FIGS. 1, 9, and 10, the ear cup 20 has a cup shape in which a disk is gently curved outward, and a plurality of through holes 22 that are through holes and a first connecting piece 30 are provided. It has an insertion hole 24 to be inserted, a band engaging port 25 projecting inwardly in a cup shape, and a band holding guide 26.

透孔２２は、耳当て装置１を装着した時に音を通過させることができ、人が耳あて装置１を装着したときに外部からの音を聞き取り易くするものである。 The through-hole 22 allows sound to pass when the ear rest device 1 is worn, and makes it easy to hear sound from the outside when a person wears the earpiece device 1.

耳カップ２０の挿入孔２４、バンド係合口２５、及びバンド保持ガイド２６は、耳カップ２０の側面から一直線上に配置される。挿入孔２４の大きさは第１連結片３０の本体３１の外形とほぼ同じであり、バンド係合口２５とバンド保持ガイド２６の幅は挿入部３４の幅とほぼ同じである。 The insertion hole 24, the band engagement port 25, and the band holding guide 26 of the ear cup 20 are arranged in a straight line from the side surface of the ear cup 20. The size of the insertion hole 24 is substantially the same as the outer shape of the main body 31 of the first connection piece 30, and the widths of the band engagement port 25 and the band holding guide 26 are substantially the same as the width of the insertion portion 34.

図９に示すように、挿入孔２４は、耳カップ２０の縦断面の中心よりも開口縁側に形成される。挿入孔２４が開口縁側に形成されることにより、使用者が耳当て装置１を頭部に装着した際に、耳カップ２０によって適度なホールド感を得ることができる。例えば、挿入孔２４が開口縁よりも離れた位置（図９の右寄り）に形成されると、ホールド感が弱くなり、使用者に外れそうな感覚を与える。 As shown in FIG. 9, the insertion hole 24 is formed on the opening edge side of the center of the longitudinal section of the ear cup 20. By forming the insertion hole 24 on the opening edge side, when the user wears the ear rest device 1 on the head, an appropriate hold feeling can be obtained by the ear cup 20. For example, if the insertion hole 24 is formed at a position away from the opening edge (to the right in FIG. 9), the hold feeling is weakened, giving the user a feeling that it is likely to come off.

また、保温カバー２は、保温効果が高い布地で形成されるものであり、一端が開口された袋状に縫製しておき、耳カップ２０を被覆する。 The heat insulation cover 2 is formed of a fabric having a high heat insulation effect, and is sewn into a bag shape having one end opened to cover the ear cup 20.

３−４．連結工程
第１及び第２のバンド部材１０１，１０２、第１連結片３０、第２連結片４０、及び耳カップ２０は、それぞれ別々に成形され、これらを組み立てることで耳当て装置１を製造することができる。 3-4. Connecting Step The first and second band members 101 and 102, the first connecting piece 30, the second connecting piece 40, and the ear cup 20 are formed separately, and the ear rest device 1 is manufactured by assembling them. be able to.

まず、図５に示すように、第１連結片３０の本体３１を第１挿通孔４４に通す。回転軸部３２が軸受部４２上に軸受される。 First, as shown in FIG. 5, the main body 31 of the first connecting piece 30 is passed through the first insertion hole 44. The rotating shaft portion 32 is supported on the bearing portion 42.

次に、第１のバンド部材１０１の第１支持部１０７を第２挿通孔４６に通す。このとき、第２連結片４０はＪ字型であるため、内側から外側へ第１支持部１０７を真っ直ぐに第２挿通孔４６に通すことができる。頭部１０７ａは、スリット１０７ｃによって変形しながら第２挿通孔４６を通り、第２挿通孔４６を通過したところでスリット１０７ｃが開いて第２連結片４０の外表面と係合し、抜け止めとなる。第１突部１０８は、第２連結片４０の歯部４８と噛み合って回転を制限する。また、第１のバンド部材１０１の押え面１１１は、軸受部４２に保持された回転軸部３２の上端に接し、回転軸部３２の上方への移動を制限しつつ回転軸部３２を中心とした回転を許容する。 Next, the first support portion 107 of the first band member 101 is passed through the second insertion hole 46. At this time, since the second connecting piece 40 is J-shaped, the first support portion 107 can be passed straight through the second insertion hole 46 from the inside to the outside. The head 107a passes through the second insertion hole 46 while being deformed by the slit 107c. When the head 107a passes through the second insertion hole 46, the slit 107c opens and engages with the outer surface of the second connecting piece 40, thereby preventing the head 107a. . The first protrusion 108 meshes with the tooth portion 48 of the second connecting piece 40 and restricts rotation. Further, the pressing surface 111 of the first band member 101 is in contact with the upper end of the rotating shaft portion 32 held by the bearing portion 42, and restricts the upward movement of the rotating shaft portion 32 while centering on the rotating shaft portion 32. Allow rotation.

さらに、図９，１０に示すように、第１連結片３０の本体３１の挿入部３４を耳カップ２０の挿入孔２４及びバンド係合口２５に挿通させ、抜け止め部３６をバンド保持ガイド２６に係合させる。第１連結片３０は、本体３１と挿入部３４との幅の違いによる段差が本体３１の挿入孔２４内への移動を制限し、抜け止め部３６とバンド保持ガイド２６との係合が本体３１の抜け方向への移動を制限する。なお、図９，１０では第１連結片３０及び第２連結片４０を省略して示している。 Further, as shown in FIGS. 9 and 10, the insertion portion 34 of the main body 31 of the first connection piece 30 is inserted into the insertion hole 24 and the band engagement port 25 of the ear cup 20, and the retaining portion 36 is attached to the band holding guide 26. Engage. In the first connecting piece 30, the step due to the difference in width between the main body 31 and the insertion portion 34 restricts the movement of the main body 31 into the insertion hole 24, and the engagement between the retaining portion 36 and the band holding guide 26 is the main body. The movement of 31 in the pulling direction is limited. 9 and 10, the first connecting piece 30 and the second connecting piece 40 are omitted.

この様にして組み立てられた耳当て装置１は、図６に示すように、本体３１が回転軸部３２を中心に内停止面４４ａと外停止面４４ｂとの間で第１連結片３０が回転可能となり、その結果、耳カップ２０を内側に折り畳むことができる。 In the ear pad 1 assembled in this way, as shown in FIG. 6, the first connecting piece 30 rotates between the inner stop surface 44 a and the outer stop surface 44 b with the main body 31 around the rotation shaft portion 32. As a result, the ear cup 20 can be folded inward.

また、図７，８に示すように、第１支持部１０７は第２挿通孔４６内で回転自在であるため、第１バンド部材１０１と耳カップ２０とは第１支持部１０７を中心に第２連結片４０及び第１連結片３０を介して図に矢印で示す範囲で相対的に回転可能である。そして、第１のバンド部材１０１は、第１連結片３０に対して、歯部４８と第１突部１０８とが噛み合う複数の位置で停止可能である。したがって、耳当て装置１によれば、ヘッドバンド１０と耳カップ２０とを所定角度に設定することができる。 As shown in FIGS. 7 and 8, since the first support portion 107 is rotatable within the second insertion hole 46, the first band member 101 and the ear cup 20 are arranged around the first support portion 107. It can be relatively rotated through the two connecting pieces 40 and the first connecting piece 30 within a range indicated by arrows in the drawing. The first band member 101 can be stopped at a plurality of positions where the tooth portion 48 and the first protrusion 108 mesh with the first connecting piece 30. Therefore, according to the ear pad 1, the headband 10 and the ear cup 20 can be set at a predetermined angle.

押え面１１１は、第１支持部１０７を中心に第１連結片３０の本体３１（耳カップ２０）を回転させたとき、回転軸部３２が軸受部４２から離れる方向への移動を制限することができる。押え面１１１は、第１支持部１０７を中心とした円弧上にあるため、回転軸部３２の上面を常に接触（わずかに離間してもよい）することができるからである。このように、耳当て装置１によれば、第１バンド部材１０１と耳カップ２０とを第１支持部１０７を中心に相対的に回転させても押え面１１１によって回転軸部３２を軸受部４２に保持することができる。 The pressing surface 111 restricts the movement of the rotary shaft portion 32 in the direction away from the bearing portion 42 when the main body 31 (ear cup 20) of the first connecting piece 30 is rotated around the first support portion 107. Can do. This is because the pressing surface 111 is on an arc centered on the first support portion 107, and thus the upper surface of the rotating shaft portion 32 can always be in contact (may be slightly separated). As described above, according to the ear rest device 1, even if the first band member 101 and the ear cup 20 are rotated relative to each other about the first support portion 107, the rotary shaft portion 32 is supported by the holding surface 111 on the bearing portion 42. Can be held in.

最後に、耳当て装置１の骨組を形成した後、ヘッドバンド１０と耳カップ２０を保温カバー２で被覆する。なお、ヘッドバンド１０を第２連結片４０と連結する前に、ヘッドバンド部分の保温カバーを被覆しておいてもよい。 Finally, after forming the framework of the ear pad 1, the headband 10 and the ear cup 20 are covered with the heat insulating cover 2. In addition, before connecting the headband 10 with the 2nd connection piece 40, you may coat | cover the heat retention cover of a headband part.

耳カップ２０に対するヘッドバンド１０の角度は、歯部４８の歯数と歯が形成される範囲に依存するが、本実施の形態における歯数や範囲に限定されるものでは無く、適宜増減することができる。例えば、歯部４８の歯先円直径を大きくしたり、隣接する歯の間隔を短くしたりすれば歯数を増やすことができる。 The angle of the headband 10 with respect to the ear cup 20 depends on the number of teeth of the tooth portion 48 and the range in which the teeth are formed, but is not limited to the number or range of teeth in the present embodiment, and may be increased or decreased as appropriate. Can do. For example, the number of teeth can be increased by increasing the diameter of the tip circle of the tooth portion 48 or shortening the interval between adjacent teeth.

図１２は、説明のため、耳当て装置１の保温カバー２を外した状態で示している。ヘッドバンド１０を縮め、ヘッドバンド１０に対して第２連結片４０を９０度回転し、第２連結片４０に対して回転軸部３２を中心に耳カップ２０（第１連結片３０）を内側に回転することで、耳カップ２０の内側面同士が向き合うようにコンパクトに折りたたむことができる。 FIG. 12 shows the ear pad 1 with the heat insulating cover 2 removed for the sake of explanation. The headband 10 is shrunk, the second connecting piece 40 is rotated 90 degrees with respect to the headband 10, and the ear cup 20 (first connecting piece 30) is placed inside the second connecting piece 40 around the rotation shaft 32. The inner cup 20 can be folded compactly so that the inner surfaces of the ear cups 20 face each other.

FIG. 13 is a perspective view of the second coupling piece 40 of the ear rest device according to the modification. FIGS. 14 to 15 are side views of partial vertical cross sections for explaining a connection structure of the headband 10, the first connection piece 30, and the second connection piece 40 according to the modification. 17 and 18 are front views of a connecting portion for explaining the rotating structure of the headband 10 with respect to the second connecting piece 40 according to the modification, FIG. 17 corresponds to FIG. 15, and FIG. 18 corresponds to FIG. To do.

変形例に係る耳当て装置は、回転軸部３２の形状と、略Ｊ字状の第２連結片４０の一方の端部が上方に長く延びる形状とが上記実施形態に係る耳当て装置１と異なる。したがって、それ以外の部分についての説明は重複することになるためここでは省略する。 The ear pad device according to the modification includes the ear pad device 1 according to the above embodiment in which the shape of the rotation shaft portion 32 and the shape in which one end portion of the substantially J-shaped second connecting piece 40 extends upward are provided. Different. Therefore, the description of the other parts will be duplicated and will be omitted here.

図１３に示すように、第２連結片４０の一端が第１挿通孔４４の高さまで延在する。このように第２連結片４０の一端が上方まで延在することで、図１４に示すように組み立てる際に、第２連結片４０の第１挿通孔４４へ第１連結片３０を導き易い。また、第１支持部１０７を第２挿通孔４６へ通す際には第２連結片４０を押し開くように弾性変形させて配置し、上方まで延びた部分で第１のバンド部材１０１の裏側を押すことで第１支持部１０７を第２挿通孔４６へ挿通する。 As shown in FIG. 13, one end of the second connecting piece 40 extends to the height of the first insertion hole 44. Since one end of the second connection piece 40 extends upward as described above, the first connection piece 30 can be easily guided to the first insertion hole 44 of the second connection piece 40 when assembling as illustrated in FIG. 14. Further, when the first support 107 is passed through the second insertion hole 46, the second connecting piece 40 is elastically deformed so as to push open, and the back side of the first band member 101 is extended by the portion extending upward. By pushing, the first support portion 107 is inserted into the second insertion hole 46.

図１４に示すように、回転軸部３２は略円柱状であるが、回転軸部３２に本体３１が接続する部分の反対側に回転停止部３３が突出して設けられる。回転停止部３３が設けられることにより、回転軸部３２は側面視で半円状の部分と略三角形の部分とが組み合わされた水滴のような外形を有する。 As shown in FIG. 14, the rotation shaft portion 32 has a substantially columnar shape, but a rotation stop portion 33 protrudes on the opposite side of the portion where the main body 31 is connected to the rotation shaft portion 32. By providing the rotation stop portion 33, the rotation shaft portion 32 has an outer shape like a water drop in which a semicircular portion and a substantially triangular portion are combined in a side view.

したがって、図１５に示すように、第１連結片３０と第２連結片４０とが組み立てられた状態で、回転軸部３２の半円状の部分は軸受部４２の曲面上に沿って回転可能である。そして、第１のバンド部材１０１（第２のバンド部材１０２も同様の構成となる）の押え面１１１と回転軸部３２の表面とは十分な間隔を有しており、互いに接触しない。第１連結片３０がこのような状態にあるときは、上記実施形態で説明したように、耳カップを内側に折り畳んだ状態である。 Therefore, as shown in FIG. 15, the semicircular portion of the rotating shaft portion 32 can rotate along the curved surface of the bearing portion 42 in a state where the first connecting piece 30 and the second connecting piece 40 are assembled. It is. The pressing surface 111 of the first band member 101 (the second band member 102 has the same configuration) and the surface of the rotary shaft portion 32 are sufficiently spaced apart from each other. When the 1st connection piece 30 exists in such a state, as demonstrated in the said embodiment, it is the state which folded the ear cup inside.

図１５に示す矢印の方向へ第１連結片３０を回転させると、図１６に示す耳カップを広げた状態になる。図１６の状態が使用者が頭部に装着する位置関係を示す。 When the 1st connection piece 30 is rotated in the direction of the arrow shown in FIG. 15, it will be in the state which extended the ear cup shown in FIG. The state of FIG. 16 shows the positional relationship that the user wears on the head.

図１６に示すように、第１連結片３０の回転停止部３３が押え面１１１にわずかな押し代を有して接触している。したがって、使用者は、図１５の状態から図１６の状態へ耳カップ（第１連結片３０）を広げる際に、そのわずかな押し代分の抵抗によって耳カップが所定の位置（使用状態の位置）になったことを理解する。そして、その押し代分は回転停止部３３及び押え面１１１の弾性変形等により吸収されて、耳カップ（第１連結片３０）を広げた位置で維持することができる。 As shown in FIG. 16, the rotation stop portion 33 of the first connecting piece 30 is in contact with the pressing surface 111 with a slight pressing allowance. Therefore, when the user spreads the ear cup (first connecting piece 30) from the state of FIG. 15 to the state of FIG. 16, the ear cup is in a predetermined position (position in the use state) by the resistance of the slight pushing allowance. ). And the pushing allowance is absorbed by the elastic deformation etc. of the rotation stop part 33 and the pressing surface 111, and it can maintain in the position which extended the ear cup (1st connection piece 30).

また、使用者が耳当て装置を折り畳もうとする場合（図１６の矢印）、耳カップ（第１連結片３０）を内側へわずかに倒すだけで回転停止部３３と押え面１１１との接触が解除されるため、押し代に起因する弾性変形の復元により勢いよく耳カップ（第１連結片３０）が図１５の状態へ自動的に戻る。これによって、使用者は容易に耳当て装置をワンタッチで容易に折り畳むことができる。 Further, when the user tries to fold the ear pad device (arrow in FIG. 16), the rotation stop portion 33 and the pressing surface 111 can be contacted by slightly tilting the ear cup (first connecting piece 30) inward. Therefore, the ear cup (first connection piece 30) automatically returns to the state shown in FIG. 15 by restoring the elastic deformation caused by the pushing allowance. Thus, the user can easily fold the ear pad device with one touch.

図１６の状態における押え面１１１と回転停止部３３との接触による抵抗は、第１突部１０８と歯部４８との間の抵抗に比べればわずかなものであるので第１のバンド部材１０１の第１支持部１０７を中心とした前後方向の回転における抵抗としてはなくてもよい。 The resistance due to the contact between the pressing surface 111 and the rotation stop portion 33 in the state of FIG. 16 is very small compared to the resistance between the first protrusion 108 and the tooth portion 48, so that the first band member 101 The resistance in rotation in the front-rear direction around the first support portion 107 may not be used.
