Description

本発明は、自動車などの車両に用いられるスタビライザ装置に関する。 The present invention relates to a stabilizer device used in a vehicle such as an automobile.

スタビライザ装置は、自動車のフロントサスペンションなどに用いられ、旋回時等において車体がロールすることを防止するようにしている。このスタビライザ装置の一例として、特許文献１に示す装置がある。
特許文献１のスタビライザ装置は、車体側に取付けられた軸部及び該軸部の両側を折曲げて左右の車輪側に取付けられた腕部からなるスタビライザを有し、該スタビライザを前記軸部において２分割して、左、右側スタビライザとし、左、右側スタビライザをクラッチ機構を介して接続し、クラッチ機構の作動により、前記左、右側スタビライザの相対回転の許容及び固定を行えるようにしている。
クラッチ機構は、右側スタビライザに連結された外筒と左側スタビライザに連結される軸状の端部側部分と、を備えている。外筒の内周部及び左側スタビライザの端部側部分の外周部には、それぞれ断面円形内壁部及びスタビライザの軸方向に見て正六角形をなす断面六角形外壁部が形成されている。 The stabilizer device is used for a front suspension of an automobile and prevents the vehicle body from rolling when turning. As an example of this stabilizer device, there is a device shown in Patent Document 1.
The stabilizer device of Patent Document 1 has a stabilizer including a shaft portion attached to the vehicle body side and arm portions attached to the left and right wheels by bending both sides of the shaft portion, and the stabilizer is attached to the shaft portion. The left and right stabilizers are divided into two, and the left and right stabilizers are connected through a clutch mechanism, and the relative rotation of the left and right stabilizers can be allowed and fixed by the operation of the clutch mechanism.
The clutch mechanism includes an outer cylinder connected to the right stabilizer and an axial end portion connected to the left stabilizer. A cross-sectional circular inner wall portion and a hexagonal cross-sectional outer wall portion forming a regular hexagon when viewed in the axial direction of the stabilizer are formed on the inner peripheral portion of the outer cylinder and the outer peripheral portion of the end side portion of the left stabilizer.

左側スタビライザの断面六角形外壁部の各平面部（軸部側平面部）と右側スタビライザの断面円形内壁との間には各１個の鋼球が介在され、アクチュエータの作動により鋼球をスタビライザの軸方向へ移動させることにより、左側スタビライザの軸部側平面部及び右側スタビライザの断面円形内壁に対する鋼球の噛合い及びその解除、ひいては左、右側スタビライザのロック（一体的結合）及び該ロックの解除を行えるようになっている。
そして、例えば車両の旋回時には、鋼球を軸部側平面部及び断面円形内壁に噛合わせて左、右側スタビライザをロックし、一体的に結合された左、右側スタビライザがねじりトルクを発生することにより、車両の旋回に伴うロール運動を抑制するようにしている。
特開２００５−１６１８８０号公報 One steel ball is interposed between each plane portion (shaft side plane portion) of the hexagonal outer cross section of the left stabilizer and the cross section circular inner wall of the right stabilizer, and the actuator operates to move the steel ball to the stabilizer. By moving in the axial direction, the steel ball engages and releases the shaft portion side plane portion of the left stabilizer and the cross-section circular inner wall of the right stabilizer, and the left and right stabilizer locks (integral connection) and the lock release. Can be done.
For example, when the vehicle turns, the left and right stabilizers are locked by engaging the steel balls with the shaft side flat portion and the circular inner wall of the cross section, and the integrally connected left and right stabilizers generate torsional torque. The roll motion accompanying the turning of the vehicle is suppressed.
JP 2005-161880 A

ところで、上述した従来技術では、断面円形内壁と軸部側平面部のそれぞれとの間には鋼球が各１個、介在されているのみである。一方、車両の右旋回に伴い車体が左側へ傾くようにロール（便宜上、左側方向ロールという。）し、また、左旋回に伴い車体が右側へ傾くようにロール（便宜上、右側方向ロールという。）する。そして、上記各ロールを抑制する上で、スタビライザは、ロール運動の方向に対応して捩じれ方向が、一方向及びこれと反対の逆方向に変化し、各ロールに対応する方向のねじりトルクを発生する。この際、これに対応して、鋼球は、軸部側平面部において、周方向に位置を変えることになる。 By the way, in the above-described conventional technology, only one steel ball is interposed between the circular inner wall of the cross section and each of the shaft side flat portions. On the other hand, it rolls so that the vehicle body tilts to the left as the vehicle turns to the left (referred to as a leftward roll for convenience), and rolls so as to tilt to the right as the vehicle turns to the left (referred to as a rightward roll for convenience). ) Then, in suppressing each roll, the stabilizer changes the twisting direction in one direction and the opposite direction corresponding to the direction of the roll motion, and generates a torsional torque in the direction corresponding to each roll. To do. At this time, the position of the steel ball is changed in the circumferential direction in the flat portion on the shaft portion side.

このため、車両がスラローム走行や左右のカーブが連続する山道での走行を行う場合などにおいて、その切り返しの際に左、右側スタビライザのロック状態が一且解除された後、逆方向でロック状態となるまでは、左、右側スタビライザはロックされないフリー状態になる。この結果、旋回方向が切り替わった際、新たな旋回に対するねじりトルクを発生するまでに、時間遅れを生じ（応答時問の遅れが生じ）、これにより制御に違和感が生じ、その分、乗り心地が低下するという問題があった。また、左、右側スタビライザのロック及びその解除を行うために鋼球を軸方向へ移動させる必要があることから、クラッチ機構（アクチュエータ）に、ある程度の軸方向長さが必要であり、車両への搭載性を悪化させるという問題もあった。 For this reason, when the vehicle is running on a slalom road or on a mountain road where left and right curves are continuous, the left and right stabilizers are unlocked and then locked in the opposite direction. Until left, the left and right stabilizers are in a free state that is not locked. As a result, when the turning direction is switched, a time delay occurs until a torsional torque for a new turn is generated (a delay occurs in response time), which causes a sense of incongruity in the control, and the ride comfort is increased accordingly. There was a problem of lowering. Further, since it is necessary to move the steel balls in the axial direction in order to lock and release the left and right stabilizers, the clutch mechanism (actuator) needs to have a certain axial length, There was also a problem of worsening the mountability.

本発明は、上記事情に鑑みてなされたものであり、左右旋回が連続的に行われる走行時においてもロール運動を応答性よく、抑制できるスタビライザ装置を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a stabilizer device that can suppress roll motion with high responsiveness even during traveling in which left and right turn is continuously performed.

上述したようにころ１８（第１、第２ころ１８ａ，１８ｂ）がリテーナ１４（大径、小径リテーナ１４ａ，１４ｂ）に配置されていることにより、大径リテーナ１４ａを回転した場合、大径リテーナ１４ａの回転に連動して小窓１７ｂに配置された第１ころ１８ａは移動する。この際、大径リテーナ１４ａの大窓１７ａに配置された第２ころ１８ｂは、小径リテーナ１４ｂの小窓１７ｂに配置されていることから、小径リテーナ１４ｂが停止状態にあれば、大径リテーナ１４ａが回転しても同位置に維持される。このため、上記大径リテーナ１４ａの回転に伴い同一平面部１２Ｈ上の第１、第２ころ１８ａ，１８ｂは相対的に近づくことになる。また、小径リテーナ１４ｂを停止状態で、上記と反対方向に大径リテーナ１４ａを回転させると第１、第２ころ１８ａ，１８ｂは相対的に離間することになる。
また、大径リテーナ１４ａを停止状態とし、小径リテーナ１４ｂを回転させる場合にも、上述したのと同様に、第１、第２ころ１８ａ，１８ｂは、相対的に近づいたり、離間したりする。
なお、小径リテーナ１４ｂ又は大径リテーナ１４ａを停止状態でなく、相手リテーナ１４と反対方向に回転させることにより、第１、第２ころ１８ａ，１８ｂは、より迅速に相対的に近づいたり、離間したりすることになる。 As described above, the rollers 18 (first and second rollers 18a, 18b) are arranged on the retainer 14 (large diameter, small diameter retainers 14a, 14b), so that when the large diameter retainer 14a is rotated, the large diameter retainer is rotated. The first roller 18a disposed in the small window 17b moves in conjunction with the rotation of 14a. At this time, the second roller 18b disposed in the large window 17a of the large diameter retainer 14a is disposed in the small window 17b of the small diameter retainer 14b. Therefore, if the small diameter retainer 14b is in a stopped state, the large diameter retainer 14a is disposed. Is maintained in the same position even when the is rotated. For this reason, the first and second rollers 18a and 18b on the same plane portion 12H come relatively closer with the rotation of the large-diameter retainer 14a. Further, when the large-diameter retainer 14a is rotated in the opposite direction with the small-diameter retainer 14b stopped, the first and second rollers 18a and 18b are relatively separated from each other.
Further, when the large-diameter retainer 14a is stopped and the small-diameter retainer 14b is rotated, the first and second rollers 18a and 18b are relatively close to each other and separated from each other as described above.
In addition, by rotating the small diameter retainer 14b or the large diameter retainer 14a not in the stopped state but in the opposite direction to the counterpart retainer 14, the first and second rollers 18a and 18b are relatively quickly approached or separated from each other. Will be.

前記第１、第２ころ１８ａ，１８ｂは、図２紙面手前から見て六角形外壁部１２のある一つの平面部１２Ｈ上で、反時計方向の角部Ｋ１から時計方向の角部Ｋ１に向けて、この順で配置されている。ころ１８（第１、第２ころ１８ａ，１８ｂ）の直径寸法は、六角形外壁部１２の角部Ｋ１から円形環状部１１までの寸法より大きい値に設定されている。 The first and second rollers 18a and 18b are directed from a counterclockwise corner K1 to a clockwise corner K1 on one flat surface 12H having the hexagonal outer wall 12 as viewed from the front of FIG. Are arranged in this order. The diameter dimension of the roller 18 (first and second rollers 18a, 18b) is set to a value larger than the dimension from the corner K1 of the hexagonal outer wall portion 12 to the circular annular portion 11.

ころ１８（第１、第２ころ１８ａ，１８ｂ）は、上述したようにリテーナ１４（大径、小径リテーナ１４ａ，１４ｂ）の回転に連動して、六角形外壁部１２の各平面部１２Ｈ上で内側軸部材１０の周方向に移動する。該ころ１８（第１、第２ころ１８ａ，１８ｂ）の移動により、該ころ１８（第１、第２ころ１８ａ，１８ｂ）が配置された位置における六角形外壁部１２の平面部１２Ｈの部分から円形環状部１１までの距離に応じて、六角形外壁部１２及び円形環状部１１に対するころ１８（第１、第２ころ１８ａ，１８ｂ）の噛合い及びその解除が行われ、ひいては、左、右側スタビライザ７ａ，７ｂがロック及びフリー状態とされ得るようになっている。 As described above, the rollers 18 (first and second rollers 18a and 18b) are linked to the rotation of the retainer 14 (large diameter and small diameter retainers 14a and 14b) on each flat surface portion 12H of the hexagonal outer wall portion 12. It moves in the circumferential direction of the inner shaft member 10. Due to the movement of the rollers 18 (first and second rollers 18a and 18b), the plane portion 12H of the hexagonal outer wall portion 12 at the position where the rollers 18 (first and second rollers 18a and 18b) are disposed. According to the distance to the circular annular part 11, the engagement of the rollers 18 (first and second rollers 18a, 18b) with the hexagonal outer wall part 12 and the circular annular part 11 and the release thereof are performed. The stabilizers 7a and 7b can be locked and free.

本実施の形態では、ソレノイド（第１、第２ソレノイド１５ａ、１５ｂ）が作動（励磁）されていない状態（図２に示す状態。初期状態）では、第１、第２ころ１８ａ，１８ｂは、六角形外壁部１２の平面部１２Ｈにおける内側軸部材１０の周方向の中央部分に配置されて相対距離が縮まった状態にあり、六角形外壁部１２及び円形環状部１１に対してころ１８（第１、第２ころ１８ａ，１８ｂ）は噛合っていないようになっている。そして、第１、第２ころ１８ａ，１８ｂが相対的に離間する方向に所定長さ（所定回転角度）、移動することにより、噛合うようになり、左、右側スタビライザ７ａ，７ｂがロックされる。
また、上述した初期状態の第１、第２ころ１８ａ，１８ｂの位置（相対距離が縮まった状態の第１、第２ころ１８ａ，１８ｂの位置）から六角形外壁部１２及び円形環状部１１に対して第１、第２ころ１８ａ，１８ｂが噛合ってねじりトルクを発生する状態になる位置までに相当する自由回転角（リミット角）は、大きい値に設定されている。 In the present embodiment, in a state where the solenoids (first and second solenoids 15a, 15b) are not activated (excited) (the state shown in FIG. 2; initial state), the first and second rollers 18a, 18b are The hexagonal outer wall portion 12 is disposed at the center portion in the circumferential direction of the inner shaft member 10 in the flat surface portion 12H, and the relative distance is reduced. The first and second rollers 18a and 18b) are not engaged with each other. Then, the first and second rollers 18a and 18b move by a predetermined length (predetermined rotation angle) in a direction in which they are relatively separated from each other, so that the left and right stabilizers 7a and 7b are locked. .
Further, the hexagonal outer wall portion 12 and the circular annular portion 11 are moved from the positions of the first and second rollers 18a and 18b in the initial state (the positions of the first and second rollers 18a and 18b in a state where the relative distance is reduced). On the other hand, the free rotation angle (limit angle) corresponding to the position where the first and second rollers 18a and 18b are engaged to generate a torsion torque is set to a large value.

ソレノイド（第１、第２ソレノイド１５ａ、１５ｂ）が作動（励磁）されていない状態（図２に示す状態。初期状態）での円形環状部１１における六角形外壁部１２の角部Ｋ１が対面する部分には、凸部２０が設けられている。凸部２０を設けることにより、六角形外壁部１２の平面部１２Ｈ及び円形環状部１１に対する第１、第２ころ１８ａ，１８ｂの噛込み度合を小さくさせるようにしている。
本実施の形態では、第１、第２ソレノイド１５ａ，１５ｂ、大径、小径リテーナ１４ａ，１４ｂが移動手段を構成している。 The corners K1 of the hexagonal outer wall portion 12 in the circular annular portion 11 face each other when the solenoids (first and second solenoids 15a and 15b) are not activated (excited) (state shown in FIG. 2; initial state). The convex part 20 is provided in the part. By providing the convex portion 20, the engagement degree of the first and second rollers 18a and 18b with respect to the flat surface portion 12H and the circular annular portion 11 of the hexagonal outer wall portion 12 is reduced.
In the present embodiment, the first and second solenoids 15a and 15b and the large and small diameter retainers 14a and 14b constitute moving means.

第１、第２ソレノイド１５ａ，１５ｂにはコントローラ２１が接続されている。コントローラ２１には、車両２のロール運動を含む車両２の挙動状態を検出する挙動状態検出手段２２が接続されている。挙動状態検出手段２２としては、操舵角センサ及び車速センサの組合せ、横加速度センサ、及び車高センサなどが用いられる。コントローラ２１は、挙動状態検出手段２２の検出内容に応じて、第１、第２ソレノイド１５ａ，１５ｂを制御する。そして、例えば挙動状態検出手段２２の検出内容が、車両２がロール運動を示す内容である場合、ロールの方向に応じて第１ソレノイド１５ａ又は第２ソレノイド１５ｂを作動させ、第１ころ１８又は第２ころ１８ｂを移動させて噛込み作動を行わせ、ロールの抑制を図るようにしている。 A controller 21 is connected to the first and second solenoids 15a and 15b. The controller 21 is connected to behavior state detection means 22 for detecting the behavior state of the vehicle 2 including the roll motion of the vehicle 2. As the behavior state detection means 22, a combination of a steering angle sensor and a vehicle speed sensor, a lateral acceleration sensor, a vehicle height sensor, and the like are used. The controller 21 controls the first and second solenoids 15 a and 15 b according to the detection contents of the behavior state detection means 22. For example, when the detection content of the behavior state detection means 22 is content indicating that the vehicle 2 performs a roll motion, the first solenoid 15a or the second solenoid 15b is operated according to the direction of the roll, and the first roller 18 or the first roller 18 The two rollers 18b are moved to perform the biting operation to suppress the roll.

上記構成のスタビライザ装置の作用を以下に説明する。
車両２が直進走行している場合にはクラッチ機構８による左、右側スタビライザ７ａ，７ｂの接続（一体的結合）は行わず（左、右側スタビライザ７ａ，７ｂのこの状態を、適宜、非接続状態という。）、左、右側スタビライザ７ａ，７ｂを分離した状態（左、右側スタビライザ７ａ，７ｂによるねじりトルクが発生しない状態。以下、適宜、フリー状態という。）にする。車両２が旋回する場合には左、右側スタビライザ７ａ，７ｂを接続し、ねじりトルクを発生させ、車両２のロール運動の抑制を図るようにしている。 The operation of the stabilizer device having the above configuration will be described below.
When the vehicle 2 is traveling straight, the left and right stabilizers 7a and 7b are not connected (integrated coupling) by the clutch mechanism 8 (this state of the left and right stabilizers 7a and 7b is appropriately disconnected) The left and right stabilizers 7a and 7b are separated (a state where no torsional torque is generated by the left and right stabilizers 7a and 7b, hereinafter referred to as a free state). When the vehicle 2 turns, the left and right stabilizers 7a and 7b are connected to generate a torsion torque so as to suppress the roll motion of the vehicle 2.

まず、直進時の作動について説明する。
コントローラ２１が、車両２が直進走行している状態にあると判断すると、第１、第２ソレノイド１５ａ，１５ｂを制御し、大径、小径リテーナ１４ａ，１４ｂを回転させ、六角形外壁部１２の各平面部１２Ｈ上にある第１、第２ころ１８ａ，１８ｂを、両者の相対距離が縮む方向ヘ移動させて、六角形外壁部１２の各平面部１２Ｈの周方向の中央部分に移動し（初期状態とし）、六角形外壁部１２及び円形環状部１１に噛み込まない状態にし、左、右側スタビライザ７ａ，７ｂを非接続状態にする。 First, the operation during straight travel will be described.
When the controller 21 determines that the vehicle 2 is running straight, the first and second solenoids 15a and 15b are controlled to rotate the large-diameter and small-diameter retainers 14a and 14b. The first and second rollers 18a and 18b on each flat surface portion 12H are moved to the direction in which the relative distance between them is reduced, and moved to the central portion in the circumferential direction of each flat surface portion 12H of the hexagonal outer wall portion 12 ( In an initial state), the hexagonal outer wall portion 12 and the circular annular portion 11 are not engaged, and the left and right stabilizers 7a and 7b are disconnected.

直進走行時に、左右輪に位相差をもつ入力があった場合、左側スタビライザ７ａに接合されている六角形外壁部１２と右側スタビライザ７ｂに接合されている外筒９とに相対回転角が生じるが、上述したように噛合い位置までの自由回転角が大きいことにより左、右側スタビライザ７ａ，７ｂは接続されず、ねじりトルクを発生することはない。これにより直進時の乗り心地悪化を防止できる。 When there is an input having a phase difference between the left and right wheels during straight traveling, a relative rotation angle is generated between the hexagonal outer wall portion 12 joined to the left stabilizer 7a and the outer cylinder 9 joined to the right stabilizer 7b. As described above, the left and right stabilizers 7a and 7b are not connected because the free rotation angle to the meshing position is large, and no torsional torque is generated. Thereby, it is possible to prevent the ride comfort from deteriorating.

次に、車両２が旋回する場合における作用を説明する。
まず、車両２が右旋回する場合、車体は左側へ傾く。このとき、六角形外壁部１２は図２（図２において紙面手前側が車両２の左側である。）で反時計回りに回転し、外筒９は時計回りに回転する。この際、コントローラ２１は第１ソレノイド１５ａを制御して大径リテーナ１４ａを時計回りに回転させて第１ころ１８を図２時計方向に移動させる。これにより第１ころ１８が六角形外壁部１２及び円形環状部１１に噛合うようになる。このため、左、右側スタビライザ７ａ，７ｂが接続状態となり、ねじりトルクが発生し、車両２のロール運動（車体が左側へ傾くロール運動）が抑制される。 Next, the operation when the vehicle 2 turns will be described.
First, when the vehicle 2 turns right, the vehicle body tilts to the left. At this time, the hexagonal outer wall portion 12 rotates counterclockwise in FIG. 2 (the front side in FIG. 2 is the left side of the vehicle 2), and the outer cylinder 9 rotates clockwise. At this time, the controller 21 controls the first solenoid 15a to rotate the large diameter retainer 14a clockwise to move the first roller 18 clockwise in FIG. As a result, the first roller 18 meshes with the hexagonal outer wall portion 12 and the circular annular portion 11. For this reason, the left and right stabilizers 7a and 7b are in a connected state, torsional torque is generated, and the roll motion of the vehicle 2 (roll motion in which the vehicle body tilts to the left) is suppressed.

また、車両２が左旋回する場合、車体は右側へ傾く。このとき、六角形外壁部１２は図２で時計回りの回転力を受け、外筒９は反時計回りの回転力を受ける。この際、コントローラ２１は、第２ソレノイド１５ｂを制御して小径リテーナ１４ｂを反時計回りに回転させて第２ころ１８ｂを図２反時計方向に移動させる。これにより第２ころ１８ｂが六角形外壁部１２及び円形環状部１１に噛合うようになる。このため、左、右側スタビライザ７ａ，７ｂが接続状態となり、ねじりトルクが発生し、車両２のロール運動（車体が右側へ傾くロール運動）が抑制される。 When the vehicle 2 turns left, the vehicle body tilts to the right. At this time, the hexagonal outer wall portion 12 receives a clockwise rotational force in FIG. 2, and the outer cylinder 9 receives a counterclockwise rotational force. At this time, the controller 21 controls the second solenoid 15b to rotate the small-diameter retainer 14b counterclockwise to move the second roller 18b counterclockwise in FIG. As a result, the second roller 18 b comes into mesh with the hexagonal outer wall portion 12 and the circular annular portion 11. For this reason, the left and right stabilizers 7a and 7b are in a connected state, torsional torque is generated, and the roll motion of the vehicle 2 (roll motion in which the vehicle body tilts to the right) is suppressed.

次に、スラローム走行のような左右の旋回が連続する場合の作動について、右旋回の後に左旋回が行われる場合を例にして説明する。
車両２が右旋回する場合には、上述したように第１ころ１８を図２時計方向に移動して、六角形外壁部１２及び円形環状部１１に噛合うようにし、左、右側スタビライザ７ａ，７ｂを接続して、ねじりトルクを発生させて、車両２のロール運動（車体が左側へ傾くロール運動）を抑制する。 Next, the operation when the left and right turns such as the slalom running are continued will be described by taking the case where the left turn is performed after the right turn as an example.
When the vehicle 2 turns to the right, the first roller 18 is moved in the clockwise direction in FIG. 2 to engage with the hexagonal outer wall portion 12 and the circular annular portion 11 as described above, and the left and right stabilizers 7a. , 7b are connected to generate torsional torque to suppress the roll motion of the vehicle 2 (roll motion in which the vehicle body tilts to the left).

このように車両２が右旋回した状態から、車両２が左旋回するようになった場合、車体が右側へ傾くことによる内側軸部材１０（六角形外壁部１２）の図２時計方向の回転、外筒９の反時計方向の回転に伴い、六角形外壁部１２及び円形環状部１１に対する第１ころ１８ａの噛合いは解除される。この第１ころ１８ａの噛合い解除と同時に、第２ソレノイド１５ｂが制御されて小径リテーナ１４ｂ、ひいては第２ころ１８ｂが図２反時計方向に回転される。
この結果、図２時計方向の回転力を受けた六角形外壁部１２、及び図２反時計方向の回転力を受けた外筒９（円形環状部１１）に第２ころ１８ｂが噛合うことにより、上述した左旋回の場合と同様に、左、右側スタビライザ７ａ，７ｂを接続して、ねじりトルクを発生させて、車両２のロール運動（車体が右側へ傾くロール運動）を抑制する。 When the vehicle 2 turns left from the state where the vehicle 2 turns right as described above, the inner shaft member 10 (hexagonal outer wall portion 12) rotates clockwise in FIG. 2 when the vehicle body tilts to the right. As the outer cylinder 9 rotates counterclockwise, the engagement of the first roller 18a with the hexagonal outer wall portion 12 and the circular annular portion 11 is released. Simultaneously with the disengagement of the first roller 18a, the second solenoid 15b is controlled to rotate the small-diameter retainer 14b and thus the second roller 18b counterclockwise in FIG.
As a result, the second roller 18b meshes with the hexagonal outer wall portion 12 receiving the clockwise rotational force in FIG. 2 and the outer cylinder 9 (circular annular portion 11) receiving the counterclockwise rotational force in FIG. As in the case of the left turn described above, the left and right stabilizers 7a and 7b are connected to generate torsional torque to suppress the roll motion of the vehicle 2 (roll motion in which the vehicle body tilts to the right).

上述したように六角形外壁部１２に第１、第２ころ１８ａ，１８ｂを設けることにより、それぞれが左右旋回時の一方の噛合いを担い、六角形外壁部１２及び円形環状部１１に対する噛合いを第１、第２ころ１８ａ，１８ｂが交互に受持つことになる。このため、車両２の左右旋回が連続的に行われる場合にも左、右側スタビライザ７ａ，７ｂの接続ひいてはねじりトルクの発生を応答性よく果たすことができ、良好な乗り心地を確保できる。 As described above, the first and second rollers 18 a and 18 b are provided on the hexagonal outer wall portion 12, so that each of them bears one meshing when turning left and right, and meshes with the hexagonal outer wall portion 12 and the circular annular portion 11. The first and second rollers 18a and 18b alternately take charge of the above. For this reason, even when the vehicle 2 is turned left and right continuously, the left and right stabilizers 7a and 7b can be connected and the torsional torque can be generated with good responsiveness, and a good riding comfort can be ensured.

また、上述した六角形外壁部１２及び円形環状部１１に対する第１、第２ころ１８ａ，１８ｂの噛込みに際し、初期状態（図２に示す状態）での円形環状部１１における六角形外壁部１２の角部Ｋ１が対面する部分には、凸部２０が設けられていることから、第１、第２ころ１８ａ，１８ｂの移動が凸部２０により抑えられる。このため、六角形外壁部１２の平面部１２Ｈ及び円形環状部１１に対する第１、第２ころ１８ａ，１８ｂの噛込み度合が小さくなり、第１、第２ころ１８ａ，１８ｂの噛込みが過剰に行われることを防止でき、第１、第２ころ１８ａ，１８ｂの噛込みに伴う制御の遅れ、ひいては乗り心地の悪化を回避できる。
また、凸部２０を設けていない場合には、左、右側スタビライザ７ａ，７ｂのロック状態からロック解除状態（フリー状態）へ移行する際にアクチュエータ（第１、第２ソレノイド１５ａ，１５ｂ）に大きな力を発生することが必要とされる。これに対して、本実施の形態では、上述したように凸部２０を設けたことにより、アクチュエータ（第１、第２ソレノイド１５ａ，１５ｂ）に必要とされる力を小さくすることができ、その分、消費動力を小さくできる。 Further, when the first and second rollers 18a and 18b are engaged with the hexagonal outer wall portion 12 and the circular annular portion 11 described above, the hexagonal outer wall portion 12 in the circular annular portion 11 in the initial state (the state shown in FIG. 2). Since the convex part 20 is provided in the part which the corner | angular part K1 faces, the movement of the 1st, 2nd roller 18a, 18b is suppressed by the convex part 20. FIG. For this reason, the engagement degree of the first and second rollers 18a and 18b with respect to the flat surface portion 12H and the circular annular portion 11 of the hexagonal outer wall portion 12 is reduced, and the engagement of the first and second rollers 18a and 18b is excessive. This can be prevented, and delays in control associated with the engagement of the first and second rollers 18a and 18b, and hence deterioration in ride comfort can be avoided.
Further, when the convex portion 20 is not provided, the actuators (first and second solenoids 15a and 15b) are large when the left and right stabilizers 7a and 7b shift from the locked state to the unlocked state (free state). It is required to generate power. In contrast, in the present embodiment, by providing the convex portion 20 as described above, the force required for the actuators (first and second solenoids 15a and 15b) can be reduced. Minutes, power consumption can be reduced.

なお、上記第１実施の形態において、大径、小径リテーナ１４ａ，１４ｂはソレノイド（第１、第２ソレノイド１５ａ，１５ｂ）で移動（回転作動）される場合を例にしたが、ソレノイド（第１、第２ソレノイド１５ａ，１５ｂ）に代えて、モータなど他のアクチュエータを用いてもよい。
また、上記第１実施の形態では、凸部２０を設ける場合を例にしたが、凸部２０を廃止して構成してもよい。
また、上記第１実施の形態では、内側部材が内側軸部材１０である場合を例にしたが、これに代えて内側部材を筒部材（内筒）としてもよい。
また、上記第１実施の形態では、多角形壁部が六角形外壁部１２である場合を例にしたが、これに代えて、三角形、四角形、五角形、 … など他の形状の多角形壁部であってもよい。 In the first embodiment, the case where the large and small diameter retainers 14a and 14b are moved (rotated) by solenoids (first and second solenoids 15a and 15b) is taken as an example. In place of the second solenoids 15a and 15b), another actuator such as a motor may be used.
Moreover, in the said 1st Embodiment, although the case where the convex part 20 was provided was taken as an example, you may abolish and comprise the convex part 20. FIG.
Moreover, in the said 1st Embodiment, although the case where the inner member was the inner shaft member 10 was taken as an example, it may replace with this and an inner member may be a cylinder member (inner cylinder).
Moreover, in the said 1st Embodiment, although the case where a polygon wall part is the hexagonal outer wall part 12 was taken as an example, it replaces with this and a polygon wall part of other shapes, such as a triangle, a square, a pentagon, ... It may be.

また、上記第１実施の形態では、内側軸部材１０（内側部材）の外周部が六角形外壁部１２（多角形壁部）とされ、外筒９（外側部材）の内周部が円形環状部１１（円形壁部）とされている場合を例にしたが、これに代えて、内側部材の外周部が円形外壁部（円形壁部）とされ、外筒９（外側部材）の内周部が多角形内壁部とされてもよい。
また、上記第１実施の形態では、外筒９（外側部材）の内周部が円形環状部１１（円形壁部）とされている場合を例にしたが、これに代えて、外筒９（外側部材）の内周部が多角形内壁部とされてもよい。 In the first embodiment, the outer peripheral portion of the inner shaft member 10 (inner member) is a hexagonal outer wall portion 12 (polygonal wall portion), and the inner peripheral portion of the outer cylinder 9 (outer member) is a circular ring shape. However, instead of this, the outer peripheral portion of the inner member is a circular outer wall portion (circular wall portion), and the inner periphery of the outer cylinder 9 (outer member) is taken as an example. The part may be a polygonal inner wall part.
Moreover, in the said 1st Embodiment, although the case where the inner peripheral part of the outer cylinder 9 (outer member) was made into the circular annular part 11 (circular wall part), it replaced with this and the outer cylinder 9 was replaced with this. The inner peripheral part of the (outer member) may be a polygonal inner wall part.

次に、本発明の第２実施の形態に係るスタビライザ装置を図５及び図６に基づいて説明する。
この第２実施の形態のスタビライザ装置１Ａは、第１実施の形態のスタビライザ装置１に比して、内側軸部材１０（内側部材）に代えて内筒２５（内側部材）を設けたこと、第１、第２ソレノイド１５ａ，１５ｂ、大径、小径リテーナ１４ａ，１４ｂから構成される移動手段に代えて、後述するピストン２６及びくさび２７等からなる移動手段を設けたこと、及び外筒９（外側部材）の内周部を円形環状部１１（円形壁部）としたのに代えて、外筒９（外側部材）の内周部を、軸方向に見て正六角形でこの正六角形の辺部からから軸方向に延びる６つの平面部２８Ｈを有する六角形内壁部２８（外側部材側多角形環状部）としたことが主に異なっている。第１実施の形態と同等部材には同等の符号を付し、その説明は、適宜、省略する。なお、内筒２５（内側部材）の外周部は、第１実施の形態と同様に、平面部１２Ｈを有する六角形外壁部１２（内側部材側多角形外壁部）とされている。 Next, the stabilizer apparatus which concerns on 2nd Embodiment of this invention is demonstrated based on FIG.5 and FIG.6.
The stabilizer device 1A of the second embodiment is provided with an inner cylinder 25 (inner member) instead of the inner shaft member 10 (inner member), compared to the stabilizer device 1 of the first embodiment. 1. In place of the moving means composed of the second solenoids 15a, 15b, the large diameter and small diameter retainers 14a, 14b, a moving means composed of a piston 26 and a wedge 27 described later is provided, and the outer cylinder 9 (outside Instead of the inner peripheral portion of the member) being the circular annular portion 11 (circular wall portion), the inner peripheral portion of the outer cylinder 9 (outer member) is a regular hexagon when viewed in the axial direction, and the sides of the regular hexagon. The main difference is that the hexagonal inner wall portion 28 (the outer member-side polygonal annular portion) has six planar portions 28H extending in the axial direction from the outer side. The same members as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted as appropriate. In addition, the outer peripheral part of the inner cylinder 25 (inner member) is made into the hexagon outer wall part 12 (inner member side polygon outer wall part) which has the plane part 12H similarly to 1st Embodiment.

図５及び図６において、内筒２５内には円錐台形状（先細り形状）のピストン２６がスタビライザ７の軸方向（図６左右方向）に移動可能に設けられている。ピストン２６は、内筒２５の底部（図６左側）側に配置されたソレノイド１５Ａに駆動され前記軸方向に移動する。
内筒２５の外周壁（符号省略）には、各平面部１２Ｈ（以下、適宜、内筒外周壁平面部１２Ｈという。）における周方向の中央部分（内筒外周壁平面部中央部分１２Ｈ０）にそれぞれ孔２９が形成されている。各孔２９には、円錐台形状のくさび２７がそれぞれ挿通されている。くさび２７は、下端面がピストン２６に当接しており、ピストン２６の前記軸方向の移動に伴い、ピストン２６の外周部のテーパ面に摺動して、各平面部２８Ｈと直交する方向に移動するようになっている。第１、第２ころ１８ａ，１８ｂは各くさび２７を間にして各平面部２８Ｈ上に配置されている。くさび２７を間にして配置される第１、第２ころ１８ａ，１８ｂには、ばね要素３０が設けられており、互いの距離が近づく方向のばね力が作用するようになっている。 5 and 6, a truncated cone-shaped (tapered) piston 26 is provided in the inner cylinder 25 so as to be movable in the axial direction of the stabilizer 7 (left-right direction in FIG. 6). The piston 26 is driven by a solenoid 15A arranged on the bottom (left side in FIG. 6) side of the inner cylinder 25 and moves in the axial direction.
An outer peripheral wall (reference numeral omitted) of the inner cylinder 25 is provided at a central portion (inner cylinder outer peripheral wall plane portion central portion 12H0) in the circumferential direction of each plane portion 12H (hereinafter, appropriately referred to as inner cylinder outer peripheral wall plane portion 12H). Each hole 29 is formed. A frustoconical wedge 27 is inserted into each hole 29. The wedge 27 is in contact with the piston 26 at the lower end surface, and slides on the taper surface of the outer peripheral portion of the piston 26 as the piston 26 moves in the axial direction, and moves in a direction perpendicular to each flat portion 28H. It is supposed to be. The first and second rollers 18a and 18b are disposed on the flat portions 28H with the wedges 27 therebetween. The first and second rollers 18a and 18b arranged with the wedge 27 in between are provided with spring elements 30 so that a spring force in a direction in which the distance between them approaches is applied.

ソレノイド１５Ａに通電されていない状態（初期状態。図５に示す状態）では、外筒９の六角形内壁部２８の平面部２８Ｈ〔以下、適宜、六角形内壁部平面部２８Ｈという。〕の周方向中央部分〔以下、六角形内壁部平面部中央部分２８Ｈ０という。〕に、内筒２５の六角形外壁部１２の角部Ｋ１（隣接する内筒外周壁平面部１２Ｈの接合部分）が対面するように配置されている。内筒２５の六角形外壁部１２の角部Ｋ１から六角形内壁部平面部２８Ｈまでの距離寸法は、ころ１８（第１、第２ころ１８ａ，１８ｂ）の直径より小さくなっている。 In a state where the solenoid 15A is not energized (initial state, the state shown in FIG. 5), the flat portion 28H of the hexagonal inner wall portion 28 of the outer cylinder 9 [hereinafter referred to as the hexagonal inner wall portion flat portion 28H as appropriate. ] In the circumferential direction [hereinafter referred to as a hexagonal inner wall plane portion 28H0. ], The corner portion K1 of the hexagonal outer wall portion 12 of the inner cylinder 25 (the joined portion of the adjacent inner cylinder outer peripheral wall plane portion 12H) is disposed so as to face each other. The distance from the corner portion K1 of the hexagonal outer wall portion 12 of the inner cylinder 25 to the hexagonal inner wall plane portion 28H is smaller than the diameter of the rollers 18 (first and second rollers 18a, 18b).

第１、第２ころ１８ａ，１８ｂは、初期状態では、各内筒外周壁平面部中央部分１２Ｈ０に配置されており、六角形内壁部２８に当接していない。また、第１、第２ころ１８ａ，１８ｂは、各内筒外周壁平面部１２Ｈの角部Ｋ１側に移動することにより、六角形内壁部２８に当接することになる。第１、第２ころ１８ａ，１８ｂの各内筒外周壁平面部１２Ｈの角部Ｋ１側への移動は、ピストン２６が図６右方向に移動することに伴い、くさび２７が内筒２５の径方向外方に移動することにより行われる。ピストン２６の図６右方向への移動は、ソレノイド１５Ａに対するコントローラ２１の励磁制御により行われる。図６の中心線３１より上側部分に、ソレノイド１５Ａが励磁されておらず移動していない状態のピストン２６（初期位置のピストン２６）を示し、図６の中心線３１より下側部分に、ソレノイド１５Ａの励磁により移動した状態のピストン２６を示す。
本第２実施の形態では、ソレノイド１５Ａ、ピストン２６及びくさび２７が移動手段を構成している。 In the initial state, the first and second rollers 18a and 18b are disposed in the central portion 12H0 of each inner cylinder outer peripheral wall plane portion, and do not contact the hexagonal inner wall portion 28. Further, the first and second rollers 18a and 18b come into contact with the hexagonal inner wall portion 28 by moving to the corner K1 side of each inner cylinder outer peripheral wall plane portion 12H. The movement of the first and second rollers 18a and 18b toward the corner K1 side of the inner cylinder outer peripheral wall plane part 12H is caused by the movement of the piston 26 in the right direction in FIG. This is done by moving out of the direction. The movement of the piston 26 in the right direction in FIG. 6 is performed by excitation control of the controller 21 with respect to the solenoid 15A. The piston 26 (the piston 26 at the initial position) in a state where the solenoid 15A is not excited and does not move is shown above the center line 31 in FIG. 6, and the solenoid below the center line 31 in FIG. The piston 26 in a state of being moved by the excitation of 15A is shown.
In the second embodiment, the solenoid 15A, the piston 26, and the wedge 27 constitute moving means.

上記構成のスタビライザ装置１Ａの作用を以下に説明する。
車両２が直進走行している場合には、ソレノイド１５Ａは励磁されておらず、ピストン２６は初期位置にあり、第１、第２ころ１８ａ，１８ｂはばね要素３０のばね力により、相対距離が短くなっている。そして、この状態（初期状態）では、第１、第２ころ１８ａ，１８ｂは、外筒９の六角形内壁部２８に当接しておらず、六角形内壁部２８及び内筒２５の六角形外壁部１２に対する第１、第２ころ１８ａ，１８ｂの噛合いは生じていない。また、六角形内壁部２８及び六角形外壁部１２が、ある位置（この場合、初期状態における位置）から第１、第２ころ１８ａ，１８ｂと噛合う位置になるまでに外筒９（六角形内壁部２８）及び内筒２５（六角形外壁部１２）に許容される回転動作角度（動作角）は、前記初期状態では、第１、第２ころ１８ａ，１８ｂが内筒外周壁平面部中央部分１２Ｈ０に配置されていることから、大きくとることができる。換言すれば、直進走行時には、第１、第２ころ１８ａ，１８ｂが内筒外周壁平面部中央部分１２Ｈ０に配置されて左、右側スタビライザ７ａ，７ｂの回転自由角が大きくとれることにより、乗り心地の悪化を防止できる。 The operation of the stabilizer device 1A having the above configuration will be described below.
When the vehicle 2 is traveling straight, the solenoid 15A is not excited, the piston 26 is in the initial position, and the first and second rollers 18a and 18b have a relative distance due to the spring force of the spring element 30. It is getting shorter. In this state (initial state), the first and second rollers 18 a and 18 b are not in contact with the hexagonal inner wall portion 28 of the outer cylinder 9, but the hexagonal inner wall portion 28 and the hexagonal outer wall of the inner tube 25. The engagement of the first and second rollers 18a and 18b with the portion 12 does not occur. Further, the outer cylinder 9 (hexagonal shape) is formed until the hexagonal inner wall portion 28 and the hexagonal outer wall portion 12 are engaged with the first and second rollers 18a and 18b from a certain position (in this case, a position in the initial state). In the initial state, the rotation operation angle (operation angle) allowed for the inner wall portion 28) and the inner cylinder 25 (hexagon outer wall portion 12) is such that the first and second rollers 18a and 18b are in the center of the inner cylinder outer peripheral wall plane portion. Since it is arranged in the portion 12H0, it can be made large. In other words, when traveling straight ahead, the first and second rollers 18a and 18b are disposed in the central portion 12H0 of the inner cylinder outer peripheral wall and the free angle of rotation of the left and right stabilizers 7a and 7b can be increased. Can be prevented.

一方、車両２が旋回しているときには、ソレノイド１５Ａへ通電しピストン２６を図６右方向へ押す。すると、くさび２７が内筒２５の径方向外方に移動する。そして、くさび２７の上記移動により、それぞれのくさび２７の両側に配置されている第１、第２ころ１８ａ，１８ｂの相対距離が長くなる。
このとき、内筒２５及び外筒９の動作角が小さくなり、ころ１８による噛合いで内筒２５及び外筒９が一体的に結合され一体に動くことができる。そして、内筒２５に接合された左側スタビライザ７ａと、外筒９に接合された右側スタビライザ７ｂが接続（一体的に結合）されることで、第１実施の形態と同様に、スタビライザ７のねじりトルクが発生し、旋回時のロールを抑制することができる。 On the other hand, when the vehicle 2 is turning, the solenoid 15A is energized to push the piston 26 rightward in FIG. Then, the wedge 27 moves outward in the radial direction of the inner cylinder 25. And by the said movement of the wedge 27, the relative distance of the 1st, 2nd roller 18a, 18b arrange | positioned at the both sides of each wedge 27 becomes long.
At this time, the operating angles of the inner cylinder 25 and the outer cylinder 9 are reduced, and the inner cylinder 25 and the outer cylinder 9 can be integrally coupled and moved integrally by the engagement of the rollers 18. Then, the left stabilizer 7a joined to the inner cylinder 25 and the right stabilizer 7b joined to the outer cylinder 9 are connected (integratedly coupled), so that the twist of the stabilizer 7 is the same as in the first embodiment. Torque is generated and rolls during turning can be suppressed.

上記第２実施の形態において、前記初期状態での六角形内壁部２８における六角形外壁部１２の角部Ｋ１が対面する部分（六角形内壁部平面部中央部分２８Ｈ０）に、六角形内壁部２８、六角形外壁部１２に対する第１、第２ころ１８ａ，１８ｂの噛込み度合を抑制する凸部（図示省略）を設けるようにしてもよい。
このように凸部（図示省略）を設けることにより、六角形外壁部１２及び六角形内壁部２８に対する第１、第２ころ１８ａ，１８ｂの噛込みに際し、第１、第２ころ１８ａ，１８ｂの移動が凸部により抑えられる。これにより、六角形外壁部１２及び六角形内壁部２８に対する第１、第２ころ１８ａ，１８ｂの噛込み度合が小さくなり、すなわち第１、第２ころ１８ａ，１８ｂの噛込みが過剰に行われることが防止される。このため、第１、第２ころ１８ａ，１８ｂの噛込みに伴う制御の遅れ、ひいては乗り心地の悪化を招く事態を回避できる。 In the second embodiment, the hexagonal inner wall portion 28 is formed on the hexagonal inner wall portion 28 in the initial state at the portion (the hexagonal inner wall portion plane portion central portion 28H0) where the corner portion K1 of the hexagonal outer wall portion 12 faces. A convex portion (not shown) that suppresses the degree of engagement of the first and second rollers 18a and 18b with respect to the hexagonal outer wall portion 12 may be provided.
By providing the convex portions (not shown) in this way, when the first and second rollers 18a and 18b are engaged with the hexagonal outer wall portion 12 and the hexagonal inner wall portion 28, the first and second rollers 18a and 18b The movement is suppressed by the convex part. Accordingly, the degree of engagement of the first and second rollers 18a and 18b with respect to the hexagonal outer wall portion 12 and the hexagonal inner wall portion 28 is reduced, that is, the first and second rollers 18a and 18b are excessively engaged. It is prevented. For this reason, it is possible to avoid a delay in control associated with the engagement of the first and second rollers 18a and 18b, and consequently a situation in which the ride comfort is deteriorated.

次に、本発明の第３実施の形態に係るスタビライザ装置を図７及び図８に基づいて説明する。第３実施の形態に係るスタビライザ装置１Ｂは第２実施の形態に係るスタビライザ装置１Ａに比して、ピストン２６に代えて断面略六角形のカム３５を設けたこと、ピストン２６を軸方向に移動させるソレノイド１５Ａに代えてカム３５を回転駆動するロータリソレノイド１５Ｂを設けたこと、ロータリソレノイド１５Ｂによりカム３５が回転し、カム３５の回転により、くさび２７が内筒２５の径方向に移動することが主に異なっている。
このスタビライザ装置１Ｂでは、初期状態（図７に示す状態）では、カム３５の平面部３５Ｈがくさび２７の底面部に当接する（カム３５の平面部３５Ｈが内筒２５の内筒外周壁平面部１２Ｈと平行になる。）ように配置されている。
本第３実施の形態では、ロータリソレノイド１５Ｂ、カム３５及びくさび２７が移動手段を構成している。 Next, the stabilizer apparatus which concerns on 3rd Embodiment of this invention is demonstrated based on FIG.7 and FIG.8. Compared to the stabilizer device 1A according to the second embodiment, the stabilizer device 1B according to the third embodiment is provided with a cam 35 having a substantially hexagonal cross section instead of the piston 26, and moves the piston 26 in the axial direction. The rotary solenoid 15B is provided in place of the solenoid 15A for rotating the cam 35, the cam 35 is rotated by the rotary solenoid 15B, and the wedge 27 is moved in the radial direction of the inner cylinder 25 by the rotation of the cam 35. Mainly different.
In this stabilizer device 1B, in the initial state (the state shown in FIG. 7), the flat portion 35H of the cam 35 abuts against the bottom surface portion of the wedge 27 (the flat portion 35H of the cam 35 is the flat portion of the inner cylinder outer peripheral wall of the inner cylinder 25). 12H in parallel).
In the third embodiment, the rotary solenoid 15B, the cam 35, and the wedge 27 constitute moving means.

そして、車両２が直進している場合には、くさび２７はばね要素３０のばね力を受けて初期位置に保持されることで、内筒２５の内筒外周壁平面部１２Ｈ上にある第１、第２ころ１８ａ，１８ｂの相対距離は短く保たれる。これにより内筒２５及び外筒９の回転自由角を大きくとることができ、乗り心地の悪化を防ぐことができる。
一方、車両２が旋回しているときにはロータリソレノイド１５Ｂが励磁されカム３５が回転する。カム３５の回転に伴いカム３５の外周部の角部Ｋ１がくさび２７の底面部に近づくことにより、くさび２７が内筒２５の径方向外方に移動する。このくさび２７の移動により、それぞれのくさび２７に両側に配置されている第１、第２ころ１８ａ，１８ｂの相対距離が大きくなり、六角形外壁部１２及び六角形内壁部２８に対して第１、第２ころ１８ａ，１８ｂが噛合って左、右側スタビライザ７ａ，７ｂが接続される。左、右側スタビライザ７ａ，７ｂが接続されることにより、スタビライザ７のねじりトルクが発生し旋回時のロール運動を抑制することができる。 When the vehicle 2 is traveling straight, the wedge 27 receives the spring force of the spring element 30 and is held at the initial position, so that the first on the inner cylinder outer peripheral wall plane portion 12 </ b> H of the inner cylinder 25. The relative distance between the second rollers 18a and 18b is kept short. Thereby, the rotation free angle of the inner cylinder 25 and the outer cylinder 9 can be taken large, and deterioration of riding comfort can be prevented.
On the other hand, when the vehicle 2 is turning, the rotary solenoid 15B is excited and the cam 35 rotates. As the cam 35 rotates, the corner K1 of the outer periphery of the cam 35 approaches the bottom surface of the wedge 27, so that the wedge 27 moves outward in the radial direction of the inner cylinder 25. By the movement of the wedge 27, the relative distance between the first and second rollers 18a and 18b arranged on both sides of each wedge 27 is increased, and the first relative to the hexagonal outer wall portion 12 and the hexagonal inner wall portion 28 is the first. The second rollers 18a and 18b mesh with each other, and the left and right stabilizers 7a and 7b are connected. By connecting the left and right stabilizers 7a and 7b, torsional torque of the stabilizer 7 is generated, and the roll motion at the time of turning can be suppressed.

次に、本発明の第４実施の形態に係るスタビライザ装置を図９及び図１０に基づいて説明する。
このスタビライザ装置１Ｃは、第１実施の形態に係るスタビライザ装置１に比して、ころ１８（第１、第２ころ１８ａ，１８ｂ）に代えて剛球４０（第１、第２剛球４０ａ、４０ｂ）を備えたことが主に異なっている。
このスタビライザ装置１Ｃでは、車両２の直進進行時及び旋回時に、第１実施の形態のスタビライザ装置１と同様の作用、効果を奏する。
また、ころ１８（第１、第２ころ１８ａ，１８ｂ）に代えて剛球４０（第１、第２剛球４０ａ、４０ｂ）を備えていることから、クラッチ機構８の軸方向の長さを短くして小型化を図ることができ、車両２への搭載性を向上できる。また、軽量化を図ることができ、消費動力の低減を図ることができる。
また、ころ１８（第１、第２ころ１８ａ，１８ｂ）に代えて剛球４０を用いることにより、リテーナ１４の軸方向の長さを短縮することが可能となり、これによりアクチュエータとリテーナ１４との接続部の負担が小さくなり、耐久性が向上する。 Next, the stabilizer apparatus which concerns on 4th Embodiment of this invention is demonstrated based on FIG.9 and FIG.10.
This stabilizer device 1C is different from the stabilizer device 1 according to the first embodiment in that a rigid ball 40 (first and second rigid balls 40a, 40b) is used instead of the roller 18 (first and second rollers 18a, 18b). The main difference is that
The stabilizer device 1 </ b> C has the same operations and effects as the stabilizer device 1 of the first embodiment when the vehicle 2 travels straight ahead and turns.
Further, since the hard ball 40 (first and second hard balls 40a and 40b) is provided instead of the roller 18 (first and second rollers 18a and 18b), the axial length of the clutch mechanism 8 is shortened. Thus, the size can be reduced, and the mounting property on the vehicle 2 can be improved. Further, the weight can be reduced and the power consumption can be reduced.
Further, by using the hard sphere 40 in place of the roller 18 (first and second rollers 18a and 18b), the axial length of the retainer 14 can be shortened, whereby the connection between the actuator and the retainer 14 can be achieved. The burden on the part is reduced and the durability is improved.

第４実施の形態では、第１実施の形態に係るスタビライザ装置１におけるころ１８（第１、第２ころ１８ａ，１８ｂ）に代えて剛球４０（第１、第２剛球４０ａ、４０ｂ）を備え場合を例にしたが、本発明は、これに限らず、前記第２，３実施の形態に係るスタビライザ装置１Ａ，１Ｂにおけるころ１８（第１、第２ころ１８ａ，１８ｂ）に代えて剛球４０（第１、第２剛球４０ａ、４０ｂ）を設けるように構成してもよい。 In 4th Embodiment, it replaces with the roller 18 (1st, 2nd roller 18a, 18b) in the stabilizer apparatus 1 which concerns on 1st Embodiment, and comprises the hard ball 40 (1st, 2nd hard ball 40a, 40b). However, the present invention is not limited to this, and instead of the rollers 18 (first and second rollers 18a and 18b) in the stabilizer devices 1A and 1B according to the second and third embodiments, a rigid ball 40 ( The first and second hard spheres 40a and 40b) may be provided.
