Description

本発明は、摩擦緩衝装置に関するものであり、特に、摩擦部材の誤組み付けを抑制する摩擦緩衝装置の構造に係るものである。   The present invention relates to a friction shock absorber, and particularly relates to a structure of a friction shock absorber that suppresses erroneous assembly of a friction member.

従来、摩擦緩衝装置は、一例として車両等に適用される。この場合には、摩擦緩衝装置は車両の動力伝達系における入力となるエンジンと出力となるトランスミッションとの間に設けられる。この様な摩擦緩衝装置は、回転中心回りに回転する第一の回転部材および第二の回転部材と、摩擦面を有して第一の回転部材と第二の回転部材との間に挟まれ、動力伝達系の入出力間で入力側に所定トルク以上が作用し相対回転が生じる場合に摩擦面で摩擦力を発生する摩擦部材とを備え、第一の回転部材と摩擦部材にそれぞれ設けられ、第一の回転部材に対して摩擦部材の設けられる位置の移動を規制する位置決め部とを備えている(例えば、特許文献1)。   Conventionally, the friction damping device is applied to a vehicle or the like as an example. In this case, the friction damping device is provided between the engine serving as an input and the transmission serving as an output in the power transmission system of the vehicle.

A friction member that generates a frictional force on the friction surface when a predetermined torque or more acts on the input side between the input and output of the power transmission system to cause relative rotation, and is provided on each of the first rotating member and the friction member. And a positioning portion for restricting movement of the position where the friction member is provided with respect to the first rotating member (for example, Patent Document 1).

特開2010−230162号公報JP 2010-230162 A

上記した装置では、第一の回転部材と第二の回転部材との間に摩擦部材を組み付ける場合、例えば、摩擦部材が第一の回転部材または第二の回転部材に対して正しい姿勢で、正規の位置に正しく組み付けられないと、正しく組み付けが行えなかったり、組み付けに時間を要するという不具合が起こり得る。このため、これを防止するよう、摩擦部材の表裏を誤って組み付けたりすることのない対策が必要となる。   In the above-described apparatus, when the friction member is assembled between the first rotation member and the second rotation member, for example, the friction member is properly positioned with respect to the first rotation member or the second rotation member. If it is not correctly assembled at the position, there may be a problem that the assembly cannot be performed correctly or that it takes time. For this reason, in order to prevent this, it is necessary to take measures to prevent the friction member from being assembled by mistake.

上記した課題を解決するために講じた手段は、回転中心回りに回転可能な第一の回転部材と、上記第一の回転部材と上記回転中心の軸方向に重なり合う重合部を有し、上記第一の回転部材に対して上記回転中心回りに回転可能な第二の回転部材と、上記第一の回転部材と上記第二の回転部材の一方に位置決めされて、上記第一の回転部材と上記重合部との間に挟まれて他方との間の摩擦面で摩擦力を発生する摩擦部材と、を備え、上記第一の回転部材に設けられ、軸方向視で上記回転中心を通るいずれの仮想直線に対しても非対称で配置された複数の第一の位置決め部と、上記摩擦部材に設けられ、上記軸方向の視線で上記第一の位置決め部のそれぞれと重なる位置に設けられ、それぞれが上記第一の位置決め部と位置合わせされ、軸方向視で上記回転中心を通るいずれの仮想直線に対しても非対称となる上記第一の位置決め部の位置に対応して配置された複数の第二の位置決め部と、を備える構成とした。上記した構成によって、複数の第一の位置決め部および複数の第二の位置決め部の配置の非対称性により、例えば、表裏の二面で摩擦係数が互いに異なる摩擦部材を組み付け時に正しい位置(姿勢)以外では、摩擦部材を第一の回転部材に組み付けることができない。   Means taken in order to solve the above-described problem includes a first rotating member that can rotate around a rotation center, and an overlapping portion that overlaps in the axial direction of the first rotating member and the rotation center. Positioned on one of the second rotating member, the first rotating member, and the second rotating member that can rotate about the rotation center with respect to the one rotating member, the first rotating member, and the first rotating member A friction member that is sandwiched between the overlapping portions and generates a frictional force on the friction surface between the other portion, provided on the first rotating member, and passes through the center of rotation when viewed in the axial direction. A plurality of first positioning portions arranged asymmetrically with respect to the virtual straight line, and provided in the friction member, provided in positions overlapping with each of the first positioning portions in the axial direction of view, Aligned with the first positioning part and viewed in the axial direction And a configuration and a plurality of second positioning portions arranged corresponding to the position of the first positioning portion is asymmetric with respect to any virtual straight line passing through the center of rotation. Due to the above configuration, due to the asymmetry of the arrangement of the plurality of first positioning portions and the plurality of second positioning portions, for example, other than the correct position (posture) when assembling friction members having different friction coefficients on the front and back surfaces Then, the friction member cannot be assembled to the first rotating member.

上記した構成において、上記摩擦部材は、円環状に構成され、上記第二の位置決め部は、円環状の内部または周縁部のいずれかに設けられる。この構成によって、摩擦部材での第二の位置決め部の位置を円環状の中で自由に設定でき、上記第一の位置決め部の非対称性により、円環状かつ板状に構成された摩擦部材の誤組み付けが抑制される。   In the configuration described above, the friction member is configured in an annular shape, and the second positioning portion is provided in either the annular interior or the peripheral portion. With this configuration, the position of the second positioning portion on the friction member can be freely set in the annular shape. Due to the asymmetry of the first positioning portion, the error of the friction member configured in an annular shape and a plate shape can be achieved. Assembly is suppressed.

また、上記摩擦緩衝装置では、例えば、上記第二の位置決め部は、周縁部には第一の位置決め部の一部が収容される切欠が設けられる。この構成によって、切欠を用いて摩擦部材を所定位置で効率良く位置決めすることができる。この場合、円環状の内部で摩擦部材を位置決めする構成と比べて、円環状の径方向での幅を薄くすることができる。   In the friction buffer device, for example, the second positioning portion is provided with a notch in which a part of the first positioning portion is accommodated in the peripheral portion. With this configuration, the friction member can be efficiently positioned at a predetermined position using the notch. In this case, the width in the radial direction of the annular shape can be reduced as compared with the configuration in which the friction member is positioned inside the annular shape.

また、上記第二の位置決め部は、同じ方向に傾斜した長穴として構成されている。この構成によって、誤組み付けした場合には長穴の傾斜方向が変わり摩擦部材の誤組み付けが抑制される。   The second positioning portion is configured as a long hole inclined in the same direction. With this configuration, when the wrong assembly is performed, the inclination direction of the long hole is changed, and the erroneous assembly of the friction member is suppressed.

また、上記摩擦部材は、分割円環状に構成され、複数の上記摩擦部材が周方向に並べて配置される。よって、分割円環状に摩擦部材を構成することにより、摩擦部材を分割にすることで小型化が可能となり、上記第一の位置決め部の非対称性により、複数の摩擦部材が周方向に並べられた構成での摩擦部材の誤組み付けが抑制される。   Moreover, the said friction member is comprised by the division | segmentation annular | circular shape, and the said some friction member is arrange | positioned along with the circumferential direction. Therefore, by configuring the friction member in a split annular shape, it is possible to reduce the size by dividing the friction member, and a plurality of friction members are arranged in the circumferential direction due to the asymmetry of the first positioning portion. Incorrect assembly of the friction member in the configuration is suppressed.

また、上記摩擦緩衝装置では、例えば、上記第一の回転部材には、少なくとも、周方向の間隔が互いに異なる三つの上記第一の位置決め部が設けられ、上記第二の回転部材には、それぞれが上記第一の位置決め部に対応する上記第二の位置決め部が設けられる。よって、第一の位置決め部の周方向の間隔の差によって、第一の位置決め部と第二の位置決め部との位置合わせが、より精度良くあるいはより容易に行われやすい。   In the friction buffer device, for example, the first rotating member is provided with at least three first positioning portions having different circumferential intervals, and the second rotating member includes The second positioning portion corresponding to the first positioning portion is provided. Therefore, the alignment between the first positioning portion and the second positioning portion is more easily or more easily performed due to the difference in the circumferential interval between the first positioning portions.

また、上記摩擦緩衝装置では、例えば、上記第一の回転部材には、少なくとも、互いに形状が異なる二つの上記第一の位置決め部が設けられ、上記第二の回転部材には、それぞれが上記第一の位置決め部に対応する上記第二の位置決め部が設けられる。よって、第一の位置決め部の形状差によって、第一の位置決め部と第二の位置決め部との位置合わせが、より精度良くあるいはより容易に行われやすい。   In the friction shock absorber, for example, the first rotating member is provided with at least two first positioning portions having different shapes, and each of the second rotating members has the first rotating member. The second positioning part corresponding to one positioning part is provided. Therefore, the first positioning portion and the second positioning portion are more easily or more easily aligned due to the shape difference of the first positioning portion.

また、上記摩擦緩衝装置では、例えば、上記第一の位置決め部および上記第二の位置決め部のうち一方には、上記第一の位置決め部および上記第二の位置決め部のうち他方側に突出した突出部が設けられ、上記他方には、上記一方側に向けて開口され上記突出部が入る第一の開口部と、上記第一の開口部とは反対側に位置され当該第一の開口部とは反対側に向けて開口され上記突出部を収容不能な第二の開口部と、が設けられる。よって、第一の開口部と第二の開口部との形状差によって、第一の位置決め部と第二の位置決め部との位置合わせが、より精度良くあるいはより容易に行われやすい。   In the friction shock absorber, for example, one of the first positioning portion and the second positioning portion has a protrusion protruding to the other side of the first positioning portion and the second positioning portion. A first opening that opens toward the one side and into which the protruding portion enters, and the first opening that is located on the opposite side of the first opening. And a second opening that is open toward the opposite side and cannot accommodate the protrusion. Therefore, the positioning of the first positioning portion and the second positioning portion is more easily or more easily performed due to the shape difference between the first opening and the second opening.

また、上記摩擦緩衝装置では、例えば、上記第一の位置決め部および上記第二の位置決め部のうち一方には、上記第一の位置決め部および上記第二の位置決め部のうち他方側に突出した突出部が設けられ、上記他方には、上記軸方向の視線で上記第一の回転部材または上記摩擦部材の周縁部に位置され上記突出部の少なくとも一部が収容される切欠が設けられると良い。よって、突出部の配置の非対称性により、周縁部に切欠が設けられた構成での誤組み付けが抑制される。   In the friction shock absorber, for example, one of the first positioning portion and the second positioning portion has a protrusion protruding to the other side of the first positioning portion and the second positioning portion. A portion is provided, and the other is preferably provided with a notch that is located at the peripheral edge of the first rotating member or the friction member with a line of sight in the axial direction and that accommodates at least a part of the protruding portion. Therefore, the asymmetry of the arrangement of the protrusions suppresses erroneous assembly in the configuration in which the peripheral edge is provided with a notch.

また、上記摩擦緩衝装置では、例えば、上記第一の位置決め部および上記第二の位置決め部は、上記軸方向の視線で上記回転中心を通る仮想直線に対して非対称に構成されると良い。よって、第一の位置決め部および第二の位置決め部の構成の非対称性により、正しい位置(姿勢)以外では、摩擦部材を第一の回転部材に組み付けることができない。   In the friction shock absorber, for example, the first positioning portion and the second positioning portion may be configured asymmetrically with respect to an imaginary straight line passing through the rotation center with the line of sight in the axial direction. Therefore, the friction member cannot be assembled to the first rotating member except for the correct position (posture) due to the asymmetry of the configuration of the first positioning portion and the second positioning portion.

また、実施形態の摩擦緩衝装置は、例えば、回転中心回りに回転可能な第一の回転部材と、上記第一の回転部材と上記回転中心の軸方向に重なり合った第一の部分と、上記軸方向の視線で上記回転中心を通るいずれの仮想直線に対しても非対称である第一の位置決め構造と、を有し、上記回転中心回りに回転可能に設けられた第二の回転部材と、上記第二の回転部材に固定され、上記第一の位置決め構造と位置合わせされ、軸方向視で上記回転中心を通るいずれの仮想直線に対しても非対称である第二の位置決め構造を有し、上記第一の回転部材と上記第一の部分との間に挟まれた摩擦部材と、を備える。よって、第一の位置決め構造の非対称性により、正しい位置(姿勢)以外では、摩擦部材を第一の回転部材に組み付けることができない。   Further, the friction shock absorber according to the embodiment includes, for example, a first rotating member that can rotate around a rotation center, a first portion that overlaps the first rotating member and the axial direction of the rotation center, and the shaft. A first positioning structure that is asymmetric with respect to any imaginary straight line passing through the rotation center with a line of sight in a direction, and a second rotation member provided rotatably around the rotation center; A second positioning structure fixed to the second rotating member, aligned with the first positioning structure, and asymmetric with respect to any imaginary straight line passing through the rotation center as viewed in the axial direction; And a friction member sandwiched between the first rotating member and the first portion. Therefore, due to the asymmetry of the first positioning structure, the friction member cannot be assembled to the first rotating member except for the correct position (posture).

また、実施形態の摩擦緩衝装置は、例えば、回転中心回りに回転可能な第一の回転部材と、上記第一の回転部材と上記回転中心の軸方向に重なり合った第一の部分を有し、上記回転中心回りに回転可能な第二の回転部材と、上記第一の回転部材に固定され、上記第一の回転部材と上記第一の部分との間に挟まれた摩擦部材と、上記第一の回転部材に設けられた第一の位置決め部と、上記摩擦部材の、上記軸方向の視線で上記第一の位置決め部と重なる位置に設けられ、上記第一の位置決め部と位置合わせされる第二の位置決め部と、を備え、上記第一の位置決め部および上記第二の位置決め部のうち一方には、上記第一の位置決め部および上記第二の位置決め部のうち他方側に突出した突出部が設けられ、上記他方には、上記一方側に向けて開口され上記突出部が入る第一の開口部と、上記第一の開口部とは反対側に位置され当該第一の開口部とは反対側に向けて開口され上記突出部を収容不能な第二の開口部と、が設けられる。よって、第一の開口部と第二の開口部との形状差によって、正しい位置(姿勢)以外では、摩擦部材を第一の回転部材に組み付けることができない。   In addition, the friction shock absorber according to the embodiment includes, for example, a first rotating member that can rotate around the rotation center, and a first portion that overlaps the first rotating member and the axial direction of the rotation center, A second rotating member rotatable around the rotation center, a friction member fixed to the first rotating member and sandwiched between the first rotating member and the first portion, A first positioning portion provided on one rotating member and a position of the friction member that overlaps the first positioning portion in the axial line of sight and are aligned with the first positioning portion. A first positioning part and a second positioning part, one of the first positioning part and the second positioning part protruding to the other side of the first positioning part and the second positioning part Part is provided, and the other side is directed toward the one side. A first opening into which the protrusion is inserted, and a first opening that is located on the opposite side of the first opening and that faces away from the first opening and cannot accommodate the protrusion. Two openings. Therefore, the friction member cannot be assembled to the first rotating member except for the correct position (posture) due to the difference in shape between the first opening and the second opening.

<第1実施形態>
本実施形態について、摩擦緩衝装置を車両のダンパ装置100に適用した場合を、一例にとって説明する。この場合、駆動力を発生するエンジン(動力装置、図示されず)とエンジンからの出力が伝達されるトランスミッション(変速装置、図示されず)との間の動力伝達系にダンパ装置100は位置されるものとする。ダンパ装置100は、エンジンからの駆動力に伴う回転変動を、以下に示す内部機構を用いて緩和することができる。なお、ダンパ装置100は、エンジンとトランスミッションとの間に位置されるものに限らず、ハイブリッド車両等では他の二つの回転要素間(例えば、エンジンと回転電機(モータジェネレータ)との間)に設けることも可能である。また、種々の車両(例えば、ハイブリッド自動車)や、回転要素を有した機械等に設けることが可能である。なお、以下に示す説明では、特に言及しない限り、図1に示す如く、軸方向は回転中心Ax(回転軸、軸心、図1参照)の軸方向、径方向は回転中心Axの径方向、周方向は回転中心Axの周方向を示すものとして定義する。
<First Embodiment>
In this embodiment, a case where the friction damping device is applied to a vehicle damper device 100 will be described as an example. In this case, the damper device 100 is positioned in a power transmission system between an engine (power device, not shown) that generates driving force and a transmission (transmission device, not shown) to which output from the engine is transmitted. Shall. The damper device 100 can mitigate rotational fluctuations accompanying the driving force from the engine using an internal mechanism shown below. The damper device 100 is not limited to being positioned between the engine and the transmission, and is provided between the other two rotating elements (for example, between the engine and the rotating electrical machine (motor generator)) in a hybrid vehicle or the like. It is also possible. Further, it can be provided in various vehicles (for example, hybrid vehicles), machines having rotating elements, and the like. In the following description, unless otherwise specified, as shown in FIG. 1, the axial direction is the axial direction of the rotation center Ax (rotation axis, axial center, see FIG. 1), the radial direction is the radial direction of the rotation center Ax, The circumferential direction is defined as indicating the circumferential direction of the rotation center Ax.

ダンパ装置100は、軸方向に薄い扁平な円盤状にて構成され、大別すると内部に、ダンパ部101と、摩擦緩衝装置となるリミッタ部102と、を有し、ダンパ部101は、リミッタ部102の径方向の内側に構成される。ダンパ部101は、コイルスプリングに代表される第一の弾性部材31の弾性的な伸縮によって、ダンパ装置100に対して入力となるエンジンで発生したトルク変動を出力側で緩和する。一方、リミッタ部102は、動力伝達系の入出力間に配置された後述する摩擦部材71、72がエンジンからの過大なトルクを受けると、摩擦部材71、72が摺動することによって相対回転が生じ、トランスミッション側への過大なトルクの伝達を遮断する。   The damper device 100 is configured in a flat disk shape that is thin in the axial direction, and roughly includes a damper portion 101 and a limiter portion 102 that serves as a friction damping device. The damper portion 101 is a limiter portion. It is comprised inside 102 of the radial direction. The damper 101 relieves torque fluctuations generated in the engine that is input to the damper device 100 on the output side by elastic expansion and contraction of the first elastic member 31 typified by a coil spring. On the other hand, when the friction members 71 and 72, which will be described later, disposed between the input and output of the power transmission system receive excessive torque from the engine, the limiter unit 102 causes relative rotation by sliding of the friction members 71 and 72. Occurs, blocking the transmission of excessive torque to the transmission side.

ダンパ部101は、サイドプレートに代表される外側部材10と、インナープレートに代表される内側部材20と、形状および材質が同一である第一の弾性部材31と、第二の弾性部材32と、同じく形状および材質が同一である第一の摺動部材41と、第二の摺動部材42と、を有する。外側部材10および内側部材20のうち一方、例えば、外側部材10が入力側のエンジンに接続され、他方である内側部材20が出力側のトランスミッションに接続される。外側部材10および内側部材20は、それぞれ、回転中心Axに対して径方向に広がった円環状かつ板状に構成され、互いに軸方向に離間した鍔状の部位を有している。外側部材10と内側部材20との回転中心Axを中心とした相対的な回動に伴って周方向において弾性的に第一の弾性部材31が伸縮する。これにより、入力側からのトルク変動があっても、出力側へはトルク変動が緩和される。また、第一の摺動部材41および第二の摺動部材42が、外側部材10と内側部材20との間で摺動することにより、摩擦抵抗が与えられる。   The damper portion 101 includes an outer member 10 represented by a side plate, an inner member 20 represented by an inner plate, a first elastic member 31 having the same shape and material, a second elastic member 32, Similarly, a first sliding member 41 and a second sliding member 42 having the same shape and material are included. One of the outer member 10 and the inner member 20, for example, the outer member 10 is connected to the input side engine, and the other inner member 20 is connected to the output side transmission. The outer member 10 and the inner member 20 are each configured in an annular and plate shape that expands in the radial direction with respect to the rotation center Ax, and have hook-shaped portions that are separated from each other in the axial direction. The first elastic member 31 elastically expands and contracts in the circumferential direction with relative rotation about the rotation center Ax between the outer member 10 and the inner member 20. Thereby, even if there is a torque fluctuation from the input side, the torque fluctuation is reduced to the output side. Further, the first sliding member 41 and the second sliding member 42 slide between the outer member 10 and the inner member 20, so that frictional resistance is given.

外側部材10は、鍔状の二つの壁部11,12(離間プレート部を形成)を有する。壁部11,12は、それぞれ、回転中心Axに対して径方向および軸方向に広がった円環状かつ板状に構成され、軸方向に広がり互いに離間している。本実施形態では、例えば、壁部11は、壁部12の軸方向の一方側(図1の左側)に位置され、壁部12は、壁部11の軸方向の他方側(図1の右側)に位置している。壁部11,12には、それぞれ、周方向に間隔をあけて複数の開口部11a,12aが設けられている。開口部11a,12aは、図1に示されるように、回転中心Axから径方向の距離が等しい位置に設けられている。壁部11および壁部12は、互いに平行となった径方向の外側にて、リベットやねじ等の結合具13で結合されている。これによって、壁部11の径方向の外側と壁部12の径方向の外側とが、径方向で互いに重なり合った状態で一体的に結合され、壁部11の少なくとも径方向の内側の領域と壁部12の少なくとも径方向の内側の領域とが軸方向に互いに離間した状態となっている。外側部材10の壁部11,12は、例えば、鉄板等の金属材料で構成される。   The outer member 10 has two bowl-shaped wall portions 11 and 12 (forming a separation plate portion). Each of the wall portions 11 and 12 is formed in an annular and plate shape that expands in the radial direction and the axial direction with respect to the rotation center Ax, and extends in the axial direction and is separated from each other. In the present embodiment, for example, the wall 11 is positioned on one side of the wall 12 in the axial direction (left side in FIG. 1), and the wall 12 is on the other side in the axial direction of the wall 11 (right side in FIG. 1). ). The walls 11 and 12 are provided with a plurality of openings 11a and 12a at intervals in the circumferential direction, respectively. As shown in FIG. 1, the openings 11 a and 12 a are provided at positions where the radial distance from the rotation center Ax is equal. The wall portion 11 and the wall portion 12 are coupled to each other by a coupling tool 13 such as a rivet or a screw on the radially outer side which is parallel to each other. As a result, the radially outer side of the wall portion 11 and the radially outer side of the wall portion 12 are integrally coupled in a state where they overlap each other in the radial direction, and at least the radially inner region of the wall portion 11 and the wall At least the radially inner region of the portion 12 is in a state of being separated from each other in the axial direction. The walls 11 and 12 of the outer member 10 are made of a metal material such as an iron plate, for example.

内側部材20は、回転中心Axを中心に回動しハブと称される筒状部21と、筒状部21の軸方向の中央部から径方向外側へと延びるプレート部を形成する壁部22と、を有する。壁部22には、周方向に間隔をあけて貫通した複数の開口部22aが設けられ、内側部材20は、例えば、鉄等の金属材料で構成される。   The inner member 20 rotates about the rotation center Ax and is a cylindrical portion 21 called a hub, and a wall portion 22 that forms a plate portion extending radially outward from the axial central portion of the cylindrical portion 21.

第一の弾性部材31は、周方向に設けられ、外側部材10と内側部材20との間に端部が挟まれており、回転中心Ax回りの相対的な回動に伴って周方向に弾性的に伸縮する。具体的に、第一の弾性部材31は、例えば、鉄等の金属材料で構成されるコイルスプリングであり、図1に示されるように、開口部11a,12a,22a内に収容されている。このような構成で、外側部材10の開口部11a,12aの周方向の一方側の縁部と内側部材20の開口部22aの周方向の他方側の縁部とが互いに近付く方向に相対的に回動すると、圧縮されて第一の弾性部材31が弾性的に縮む。逆に、開口部11a,12a,22a内で弾性的に縮んだ状態で、外側部材10の開口部11a,12aの周方向の一方側の縁部と内側部材20の開口部22aの周方向の他方側の端部とが互いに遠ざかる方向に相対的に回動すると、圧縮された状態から第一の弾性部材31は弾性的に伸びる。第一の弾性部材31は、弾性的に縮むことによりダンパ装置100に入力されるトルクを圧縮力として蓄え、一方、弾性的に伸びることにより圧縮力をトルクとして放出する。第一の弾性部材31は、このように、外側部材10と内側部材20との間に位置され、外側部材10と内側部材20とに周方向に沿って挟まれて、周方向に沿って弾性的に伸縮する。この様にして、ダンパ部101は、第一の弾性部材31の伸縮によって、動力伝達系における入力側で生じるトルク変動を吸収し、出力側で緩和することができる。   The first elastic member 31 is provided in the circumferential direction, and an end is sandwiched between the outer member 10 and the inner member 20, and is elastic in the circumferential direction with relative rotation around the rotation center Ax.

When it rotates, it is compressed and the first elastic member 31 is elastically contracted. Conversely, in a state where the openings 11a, 12a, and 22a are elastically contracted, one edge of the outer member 10 in the circumferential direction of the openings 11a and 12a and the circumferential direction of the opening 22a of the inner member 20 are provided. When the end portion on the other side is relatively rotated away from each other, the first elastic member 31 is elastically extended from the compressed state. The first elastic member 31 stores the torque input to the damper device 100 as a compression force by being elastically contracted, and releases the compression force as a torque by being elastically extended. Thus, the 1st elastic member 31 is located between the outer member 10 and the inner member 20, is pinched | interposed into the outer member 10 and the inner member 20 along the circumferential direction, and is elastic along the circumferential direction. Stretch and contract.

Further, in the axial direction, it is sandwiched between the wall portion 11 and the wall portion 22 extending in the radial direction. Similarly, the second sliding member 42 is sandwiched between the radially inner end portion of the wall portion 12 and the outer peripheral surface of the tubular portion 21 in the radial direction. In the axial direction, the wall portion 12 and the wall portion 22 extending in the radial direction from the tubular portion 21 are sandwiched. The first sliding member 41 and the second sliding member 42 have sliding surfaces 41 a and 42 a that function as friction surfaces on the side of the wall portion 22 extending in the radial direction.

第二の弾性部材32は、壁部12と第二の摺動部材42との間に位置され、壁部11および第二の摺動部材42に対して、互いに離間する方向に弾性力を与えている。また、第二の弾性部材32は、摺動面41a,42aと径方向で同じ長さとなり、軸方向に壁部22を介して重なっている。すなわち、第二の弾性部材32は、径方向に延びる壁部22と第一の摺動部材41とを間に挟んだ状態で第二の摺動部材42を壁部11に押し付けている。このように、第二の弾性部材32は、摺動面41a,42aのそれぞれに、摺動抵抗(摩擦抵抗)を与えることができる。第二の弾性部材31は、例えば、金属材料で構成された円環状の板バネであり、皿バネ、コーンスプリングを用いても良い。   The second elastic member 32 is positioned between the wall portion 12 and the second sliding member 42, and applies an elastic force to the wall portion 11 and the second sliding member 42 in a direction away from each other. ing. The second elastic member 32 has the same length as the sliding surfaces 41 a and 42 a in the radial direction and overlaps with the wall portion 22 in the axial direction. That is, the second elastic member 32 presses the second sliding member 42 against the wall portion 11 with the wall portion 22 extending in the radial direction and the first sliding member 41 sandwiched therebetween. Thus, the second elastic member 32 can give sliding resistance (friction resistance) to each of the sliding surfaces 41a and 42a.

Here, although not shown in the figure, in a configuration in which the plurality of protrusions 52 (openings 71a) are simply arranged at equal intervals along the circumferential direction, the first friction member 71 is displaced in the circumferential direction ( The protrusion 52 and the opening 71a are aligned even in the rotation orientation and the reverse (inverted) orientation. In this regard, in the arrangement of the plurality of projecting portions 52 and 52d (opening portions 71a and 71ad) of the present embodiment described above, all the opening portions 71a and 71ad and all the projecting portions are disposed in the posture reversed from the intended posture. 52 and 52d cannot be aligned. Therefore, according to the present embodiment, assembly in a posture other than the predetermined posture, that is, erroneous assembly due to turning over is suppressed.

上述したように、図2では回転中心Axを通る仮想直線Pの角度間隔が一定の角度間隔S1の突出部および開口部を七つ設けた構成で説明したが、これに限定されるものではない。例えば、回転中心Axを通り隣り合う突出部(開口部)の中心を通る2つの仮想直線Pの成す角度を所定角度θ1にしたり、摩擦部材を位置決めする位置決め部の径の大きさ等に代表される何等かの規則性を持って摩擦部材が所期の位置で設けられるように、上記した突出部(開口部)を設けることもできる。この場合、周方向で見た場合に隣り合う突出部(開口部)同士の距離や回転中心Axに対する角度が等しく規則性を持って設けられた複数の突出部52(開口部71a)は、所望の正規位置に設けられることから言葉上、
正規位置決め部と定義することができる。
As described above, although FIG. 2 has been described with the configuration in which the seven protrusions and the openings having the angular interval S1 with the constant angular interval P1 passing through the rotation center Ax are provided, the present invention is not limited to this. . For example, the angle formed by two virtual straight lines P passing through the center of rotation Ax and passing through the centers of adjacent protrusions (openings) is set to a predetermined angle θ1, or the diameter of the positioning portion for positioning the friction member is typified. It is also possible to provide the above-described protrusion (opening) so that the friction member is provided at an intended position with some regularity. In this case, when viewed in the circumferential direction, the distance between adjacent protrusions (openings) and the angle with respect to the rotation center Ax are equal and the plurality of protrusions 52 (openings 71a) provided with regularity are desired. From the fact that it is provided in the regular position of,
It can be defined as a regular positioning part.

一方、突出部52d(開口部71ad)に代表されるように、周方向で見た場合に隣り合う規則性を何ら持たない位置に設けられた少なくとも一つの突出部(開口部)は、正規位置決め部とは異なる特異位置決め部と言葉上、定義することができる。   On the other hand, as represented by the protrusion 52d (opening 71ad), at least one protrusion (opening) provided at a position having no regularity when viewed in the circumferential direction is properly positioned. It can be defined in terms of a unique positioning part different from the part.

この様に摩擦部材71に対し、周方向において見た場合、所望の位置に正規位置決め部および特異位置決め部を設けることにより、例えば、第一の摩擦部材71を第一の回転部材50に対して組み付ける場合、所期の姿勢(正常な組み付け)では正規位置決め部および特異位置決め部の位置が合致して組み付けが行えるが、所期の姿勢から摩擦部材71が裏返された姿勢(誤組み付け)で組み付けを行った場合には、正規位置決め部の位置は合致するが、特異位置決め部の位置が裏返しにより所期位置からずれた位置となるために組み付けが行えなくなる。このことから、摩擦部材71の誤組み付けを正規位置決め部に対して位置が異なる特異位置決め部を設けるという簡単な構成で、誤組み付けが抑制される。   In this way, when the friction member 71 is viewed in the circumferential direction, by providing the normal positioning portion and the specific positioning portion at a desired position, for example, the first friction member 71 is attached to the first rotating member 50. When assembling, the position of the normal positioning part and the specific positioning part can be assembled in the intended posture (normal assembly), but the friction member 71 can be assembled with the flipped position of the desired position (incorrect assembly). In this case, the position of the normal positioning portion matches, but the position of the specific positioning portion is shifted from the intended position due to turning over, so that the assembly cannot be performed. From this, erroneous assembly of the friction member 71 is suppressed with a simple configuration in which a unique positioning portion having a position different from that of the normal positioning portion is provided.

なお、本実施形態では、第三の回転部材80に設けられる突出部83ならびに第二の摩擦部材72の開口部72aも、突出部52および開口部71aと上述した構成と同様に、軸方向の視線で回転中心Axを通るいずれの仮想直線Pに対しても非対称(非線対称)であるように配置されている。また、本実施形態では、第一の位置決め部30と第二の位置決め部40との位置合わせによって、第一の摩擦部材71と第一の回転部材50とが凹凸嵌合若しくは係合により一体化され、第二の摩擦部材72と第三の回転部材80とが同じように凹凸嵌合若しくは係合により一体化されている。すなわち、第一の摩擦部材71および第二の摩擦部材72は、第一の回転部材50および第三の回転部材80と回転中心Ax回りに一体的に回転する。第一の摩擦部材71および第二の摩擦部材72は、例えば、ガラス繊維材料や合成ゴム等を含有した合成樹脂材料等で構成される。   In the present embodiment, the protrusion 83 provided on the third rotating member 80 and the opening 72a of the second friction member 72 are also axially arranged in the same manner as the protrusion 52 and the opening 71a. It arrange | positions so that it may be asymmetrical (non-linear symmetry) with respect to any virtual straight line P which passes along the rotation center Ax by a visual line. In the present embodiment, the first friction member 71 and the first rotating member 50 are integrated by uneven fitting or engagement by aligning the first positioning portion 30 and the second positioning portion 40. In addition, the second friction member 72 and the third rotation member 80 are similarly integrated by uneven fitting or engagement. That is, the first friction member 71 and the second friction member 72 rotate integrally with the first rotation member 50 and the third rotation member 80 around the rotation center Ax. The first friction member 71 and the second friction member 72 are made of, for example, a synthetic resin material containing glass fiber material or synthetic rubber.

また、図1に示されるように、第四プレート、サポートプレートと称される第四の回転部材90は、筒状部91と、筒状部91の両側にそれぞれ壁部92,93と、を有する。筒状部91は、回転中心Axを中心とする円筒状に構成され、第三の回転部材80の引掛部82より径方向の外側に位置されている。壁部92(第一の壁部)は、筒状部91の他方端から径方向の外側に向けて突出し、回転中心Axに対して径方向に広がった円環状かつ板状に構成されている。壁部92は、筒状部91の他方端に設けられ、第一の回転部材50の壁部51と軸方向に重なっている。また、壁部92には、周方向に間隔をあけて穴による複数の開口部92aが設けられている。開口部92aは、壁部51aの開口部51bと軸方向に重なり合っている。第一の回転部材50と第四の回転部材90とは、開口部51bおよび開口部92aに通されたボルトやねじ等の結合具によって、例えば、エンジン側に設けられるフライホイール等と結合される。すなわち、第四の回転部材90は、結合具(図示されず)によって、第一の回転部材50と回転中心Ax回りに一体的に回転する。壁部93(第二の壁部)は、筒状部91の一方端から径方向の内側に向けて張り出し(突出し)、回転中心Axに対して直交して径方向に広がった円環状かつ板状に構成されている。壁部93は、筒状部91の軸方向の一方側(図1では左側)の端部に設けられ、第三の回転部材80の壁部81の軸方向の一方側で当該壁部81と軸方向に離間した状態で重なっている。第四の回転部材90もまた、例えば、鉄等の金属材料で構成される。   As shown in FIG. 1, a fourth rotating member 90 called a fourth plate or a support plate includes a cylindrical portion 91 and walls 92 and 93 on both sides of the cylindrical portion 91, respectively. Have. The cylindrical portion 91 is configured in a cylindrical shape centered on the rotation center Ax, and is positioned on the outer side in the radial direction from the hook portion 82 of the third rotating member 80. The wall portion 92 (first wall portion) is configured to have an annular shape and a plate shape that protrudes outward in the radial direction from the other end of the cylindrical portion 91 and expands in the radial direction with respect to the rotation center Ax. . The wall portion 92 is provided at the other end of the cylindrical portion 91 and overlaps the wall portion 51 of the first rotating member 50 in the axial direction. The wall portion 92 is provided with a plurality of openings 92a formed by holes at intervals in the circumferential direction. The opening 92a overlaps the opening 51b of the wall 51a in the axial direction. The first rotating member 50 and the fourth rotating member 90 are coupled to, for example, a flywheel or the like provided on the engine side by a coupling tool such as a bolt or a screw passed through the opening 51b and the opening 92a. . In other words, the fourth rotating member 90 rotates integrally around the first rotating member 50 and the rotation center Ax by a coupler (not shown). The wall portion 93 (second wall portion) projects (projects) radially inward from one end of the cylindrical portion 91, and is an annular plate extending in the radial direction perpendicular to the rotation center Ax. Configured. The wall portion 93 is provided at an end portion on one axial side (left side in FIG. 1) of the cylindrical portion 91, and on one side in the axial direction of the wall portion 81 of the third rotating member 80, Overlapping in the axially separated state. The fourth rotating member 90 is also made of a metal material such as iron, for example.

第三の弾性部材33は、第四の回転部材90の壁部93と、第三の回転部材80の壁部81との間に位置され、壁部93および壁部81に対して、互いに離間する方向の弾性力を与えている。また、第三の弾性部材33は、摺動面となる第一の面71b,72bと軸方向に重なっている。第三の弾性部材33は、第二の摩擦部材72、第二の回転部材60の壁部61、および第一の摩擦部材71を間に挟んだ状態で第三の回転部材80の壁部81を第一の回転部材50の壁部51に押し付けている。すなわち、第三の弾性部材33の付勢力による荷重によって、第二の摩擦部材72と第二の回転部材60との間で摩擦力が生じ、第二の回転部材60と第一の摩擦部材71との間で摩擦力が生じる。本実施形態では、第一の摩擦部材71と第二の摩擦部材72との間で最大静止摩擦力を超えるトルク差となるまで、第一の回転部材50、第三の回転部材80、ならびに第四の回転部材90と第二の回転部材60とはすべらない。第三の弾性部材33は、例えば、金属材料で構成された円環状(円筒状)の板バネであり、皿バネ、コーンスプリングであっても良い。   The third elastic member 33 is positioned between the wall portion 93 of the fourth rotating member 90 and the wall portion 81 of the third rotating member 80, and is separated from the wall portion 93 and the wall portion 81. The elastic force is given in the direction. The third elastic member 33 overlaps the first surfaces 71b and 72b serving as sliding surfaces in the axial direction. The third elastic member 33 includes the second friction member 72, the wall portion 61 of the second rotation member 60, and the wall portion 81 of the third rotation member 80 with the first friction member 71 interposed therebetween. Is pressed against the wall 51 of the first rotating member 50. That is, a frictional force is generated between the second friction member 72 and the second rotating member 60 by the load due to the urging force of the third elastic member 33, and the second rotating member 60 and the first friction member 71. A frictional force is generated between In the present embodiment, the first rotating member 50, the third rotating member 80, and the first rotating member 50 until the torque difference that exceeds the maximum static frictional force between the first friction member 71 and the second friction member 72 is reached. The four rotating members 90 and the second rotating member 60 do not slide. The third elastic member 33 is, for example, an annular (cylindrical) plate spring made of a metal material, and may be a disc spring or a cone spring.

以上の構成によって正しい組み付けが行われたリミッタ部102では、ダンパ装置100の入出力間のトルク差が、許容される設定範囲内の閾値より小さい状態では、第三の弾性部材33の付勢力によってリミッタ部102では滑りが生じず、ダンパ部101とリミッタ部102とを含むダンパ装置100が一体的に回転する。一方、ダンパ装置100の入出力間のトルク差が閾値より大きい状態では、リミッタ部102で第三の弾性部材33の付勢力による摩擦力、即ち、最大静止摩擦力を超えた状態になると第一の面71b、72bと摩擦発生部としての第一の部分61aとの間で滑りが生じ、ダンパ装置100の入出力間の間で滑りが生じる。リミッタ部102は、このように必要以上のトルクがダンパ装置100の入出力間に作用した場合にトルクリミッタとして機能し、入力側で過大なトルク変動が生じても、出力側への過大なトルクの伝達が抑制される。   In the limiter unit 102 that has been correctly assembled by the above configuration, when the torque difference between the input and output of the damper device 100 is smaller than the threshold value within the allowable setting range, the biasing force of the third elastic member 33 is used. The limiter unit 102 does not slip, and the damper device 100 including the damper unit 101 and the limiter unit 102 rotates integrally. On the other hand, when the torque difference between the input and output of the damper device 100 is larger than the threshold value, the frictional force generated by the urging force of the third elastic member 33 in the limiter unit 102, that is, the maximum static frictional force is exceeded. Slip occurs between the surfaces 71b and 72b of the first portion 61a and the first portion 61a as the friction generating portion, and slip occurs between the input and output of the damper device 100. The limiter unit 102 functions as a torque limiter when an excessive torque acts between the input and output of the damper device 100 in this way, and an excessive torque to the output side is generated even if an excessive torque fluctuation occurs on the input side. Transmission is suppressed.

以上のように、本実施形態では、例えば、第一の回転部材50の複数の第一の位置決め部30ならびに第一の摩擦部材71の複数の第二の位置決め部40が、それぞれ、軸方向視で回転中心Axを通るいずれの仮想直線Pに対しても非対称(非線対称)であるように配置されている。よって、本実施形態によれば、例えば、複数の第一の位置決め部30の非対称性ならびに複数の第二の位置決め部40の非対称性により、正しい組み付け位置(姿勢)以外では、第一の摩擦部材71を第一の回転部材50に組み付けることができない。よって、本実施形態によれば、例えば、正しい所定の姿勢以外の姿勢での組み付け、すなわち、第一の摩擦部材71および第二の摩擦部材72の誤組み付けが、コストアップせず簡単な構成で、確実に抑制される。   As described above, in the present embodiment, for example, the plurality of first positioning portions 30 of the first rotating member 50 and the plurality of second positioning portions 40 of the first friction member 71 are respectively viewed in the axial direction. Are arranged so as to be asymmetric (non-linearly symmetric) with respect to any virtual straight line P passing through the rotation center Ax. Therefore, according to this embodiment, for example, the first friction member other than the correct assembly position (posture) due to the asymmetry of the plurality of first positioning portions 30 and the asymmetry of the plurality of second positioning portions 40. 71 cannot be assembled to the first rotating member 50. Therefore, according to the present embodiment, for example, assembly in a posture other than the correct predetermined posture, that is, erroneous assembly of the first friction member 71 and the second friction member 72 with a simple configuration without increasing the cost. , Surely suppressed.

また、本実施形態では、例えば、第一の摩擦部材71が、円環状かつ板状に構成されている。よって、本実施形態によれば、例えば、複数の第一の位置決め部30の配置の非対称性により、円環状かつ板状に構成された第一の摩擦部材71の誤組み付けが抑制される。   Moreover, in this embodiment, the 1st friction member 71 is comprised by the annular | circular shape and plate shape, for example. Therefore, according to the present embodiment, for example, due to the asymmetry of the arrangement of the plurality of first positioning portions 30, erroneous assembly of the first friction member 71 configured in an annular shape and a plate shape is suppressed.

また、本実施形態では、例えば、第一の回転部材50および第一の摩擦部材71には、周方向の間隔が互いに異なる少なくとも三つの第一の位置決め部30および第一の位置決め部30に対応する位置に第二の位置決め部40が設けられている。よって、本実施形態によれば、例えば、第一の位置決め部30の中心の周方向の間隔の差によって、第一の位置決め部30と第二の位置決め部40との位置合わせが、より精度良くあるいはより容易に行われやすい。   In the present embodiment, for example, the first rotating member 50 and the first friction member 71 correspond to at least three first positioning portions 30 and first positioning portions 30 having different circumferential intervals. A second positioning portion 40 is provided at the position to be operated. Therefore, according to the present embodiment, for example, the alignment between the first positioning unit 30 and the second positioning unit 40 is more accurately performed due to the difference in the circumferential interval at the center of the first positioning unit 30. Or it is easy to be performed more easily.

なお、本実施形態では、例えば、第一の回転部材50や第三の回転部材80に突出部52,83(第一の位置決め部30)が一体で設けられた場合を例示したが、例えば、第二の回転部材60に突出部52,83(第一の位置決め部30)が一体で設けられ、第二の回転部材60と第一の摩擦部材71および第二の摩擦部材72とが回転中心Ax回りに一体的に回転する構成であってもよい。この場合、第一の摩擦部材71と第一の回転部材50との間が摺動すると共に、第二の摩擦部材72と第三の回転部材80との間が同時に摺動する。   In the present embodiment, for example, the case where the projecting portions 52 and 83 (first positioning portion 30) are integrally provided on the first rotating member 50 or the third rotating member 80 is exemplified. The protrusions 52 and 83 (first positioning portion 30) are integrally provided on the second rotating member 60, and the second rotating member 60, the first friction member 71, and the second friction member 72 are the rotation center. It may be configured to rotate integrally around Ax. In this case, the first friction member 71 and the first rotating member 50 slide and the second friction member 72 and the third rotating member 80 slide simultaneously.

また、本実施形態では、例えば、リミッタ部102を構成する第一の回転部材50(第三の回転部材80)および第一の摩擦部材71(第二の摩擦部材72)に第一の位置決め部30および第二の位置決め部40がそれぞれ設けられた場合を例示したが、例えば、ダンパ部101のサイドプレートと称される外側部材10、第一の摺動部材41(第二の摺動部材42)に第一の位置決め部30および第二の位置決め部40がそれぞれ設けられる構成であってもよい。   In the present embodiment, for example, the first positioning member is connected to the first rotating member 50 (third rotating member 80) and the first friction member 71 (second friction member 72) constituting the limiter unit 102. 30 and the second positioning part 40 are exemplified, for example, the outer member 10 called the side plate of the damper part 101, the first sliding member 41 (second sliding member 42), for example. ) May be provided with the first positioning part 30 and the second positioning part 40, respectively.

<第2実施形態>
図3に示される本実施形態にかかるリミッタ部102は、上記した第1実施形態のリミッタ部102と同様の構成を備え、第1実施形態における第一の位置決め部と第二の位置決め部の位置、形状が異なる。それ故に、本実施形態によっても、第1実施形態で説明した構成に基づき、同様の効果が得られる。
Second Embodiment
The limiter unit 102 according to the present embodiment shown in FIG. 3 has the same configuration as the limiter unit 102 of the first embodiment described above, and the positions of the first positioning unit and the second positioning unit in the first embodiment. The shape is different. Therefore, according to this embodiment, the same effect can be obtained based on the configuration described in the first embodiment.

即ち、本実施形態では、図3に示す構成とすることができ、ここでは、第一の摩擦部材71Cを例にとって説明する。図3に示すように、第一の摩擦部材71Cには、第一の回転部材50の突出部52の設けられる位置に対応して、複数の開口部71nが設けられている。開口部71nは、例えば、第一の摩擦部材71Cの外径の周縁部(外周縁部)に半円状の切欠が設けられている。半円状の開口部71nは、円環状となった第一の摩擦部材71Cの外周部71xに対して周方向に設けられ、内径に向けて半円状に凹んでいる。開口部71nには、突出部52の少なくとも一部、例えば、内径側の半分の領域が収容される。開口部71n(突出部52も同様)の設けられる位置は回転中心Axに対して周方向で7つ(45°間隔)で規則的に設けられていると共に、開口部71nd(突出部52d)は隣り合う開口部71nとは45°以外の角度位置に設けられる。この場合、円柱状となった突出部52の中心がそれぞれ外周延長線上の位置となる様にしている。本実施形態では、外周に切欠が設けられた複数の開口部71nによって、複数の第二の位置決め部40Cが構成されている。   That is, in this embodiment, it can be set as the structure shown in FIG. 3, and it demonstrates here taking the 1st friction member 71C as an example. As shown in FIG. 3, the first friction member 71 </ b> C is provided with a plurality of openings 71 n corresponding to the positions where the protrusions 52 of the first rotating member 50 are provided. In the opening 71n, for example, a semicircular cutout is provided in the outer peripheral edge (outer peripheral edge) of the first friction member 71C. The semicircular opening 71n is provided in the circumferential direction with respect to the outer peripheral portion 71x of the first friction member 71C having an annular shape, and is recessed in a semicircular shape toward the inner diameter. The opening 71n accommodates at least a part of the protrusion 52, for example, a half region on the inner diameter side. The positions where the openings 71n (similar to the protrusions 52) are provided are regularly provided at seven (45 ° intervals) in the circumferential direction with respect to the rotation center Ax, and the openings 71nd (projections 52d) are The adjacent opening 71n is provided at an angular position other than 45 °. In this case, the center of the columnar protrusion 52 is positioned on the outer peripheral extension line. In the present embodiment, a plurality of second positioning portions 40C are configured by a plurality of openings 71n having notches on the outer periphery.

突出部52,52dに代表される第一の位置決め部30および開口部71n,71ndに代表される第二の位置決め部40Cの設けられる位置は、第一の摩擦部材71C(第二の摩擦部材)の径方向の中央ではなく、円環状となった外周に設けられている点が第1実施形態とは異なっている。従って、本実施形態によれば、例えば、開口部71n,71ndが第一の摩擦部材71Cの外周部71xに設けられた切欠として構成されているため、第一の摩擦部材71Cの円環状となった径方向の幅で第二の回転部材60との間で摩擦力を確保することができ、その幅を第1実施形態と比べて薄くすることができる。なお、本実施形態では、図1で説明した第二の摩擦部材にあっても、第一の摩擦部材71Cと同様に構成されうる。また、本実施形態では、第一の摩擦部材71Cに開口部71n,71ndが設けられ、第一の回転部材50に突出部52,52dが設けられた場合を例示したが、第一の摩擦部材71Cに一体で回転中心Axの軸方向に突出部52,52dが設けられ、第一の回転部材50に切欠となった開口部71n,71ndが直接設けられる構成であってもよい。   The positions of the first positioning portion 30 typified by the protrusions 52 and 52d and the second positioning portion 40C typified by the openings 71n and 71nd are provided at the first friction member 71C (second friction member). This is different from the first embodiment in that it is provided not on the radial center but on the outer periphery in the shape of a ring. Therefore, according to the present embodiment, for example, since the openings 71n and 71nd are configured as notches provided in the outer peripheral portion 71x of the first friction member 71C, the first friction member 71C has an annular shape. A frictional force can be ensured with the second rotating member 60 with the width in the radial direction, and the width can be reduced as compared with the first embodiment. In the present embodiment, the second friction member described with reference to FIG. 1 can be configured similarly to the first friction member 71C. Moreover, in this embodiment, although the opening parts 71n and 71nd were provided in the 1st friction member 71C and the protrusion parts 52 and 52d were provided in the 1st rotation member 50, the 1st friction member was illustrated. The protrusions 52 and 52d may be provided integrally with the 71C in the axial direction of the rotation center Ax, and the openings 71n and 71nd that are notched in the first rotation member 50 may be directly provided.

<第3実施形態>
図4に示される実施形態にかかるリミッタ部102は、上記した第1実施形態のリミッタ部102と同様の構成を備え、第2実施形態の変形例を示しており、第2実施形態における第一の位置決め部と第二の位置決め部の位置が主として異なる。従って、本実施形態においても、第1実施形態および第2実施形態と同様の効果が得られる。
<Third Embodiment>
The limiter unit 102 according to the embodiment shown in FIG. 4 has the same configuration as the limiter unit 102 of the first embodiment described above, and shows a modification of the second embodiment. The positions of the positioning part and the second positioning part are mainly different. Therefore, also in this embodiment, the same effect as the first embodiment and the second embodiment can be obtained.

即ち、本実施形態では、例えば、図4に示されるように、第一の摩擦部材71Dを例にとって説明する。第一の摩擦部材71Dには、第一の回転部材50に設けられた複数の突出部52,52dの位置に対応して、複数の開口部71o,71odが設けられている。開口部71o,71odは、例えば、第一の摩擦部材71Dの周縁部(内周縁部)に設けられた半円状の切欠として構成されている。開口部71o,71odは、第一の摩擦部材71Dの円環状となった内径の周縁部(内周縁部)に設けられ、径方向の外側に向けて半円状に凹んでいる。開口部71o,71odには、突出部52の少なくとも一部、例えば、半分の領域が収容される。開口部71o(突出部52も同様)の設けられる位置は回転中心Axに対して周方向で7つ(45°間隔)で規則的に設けられていると共に、開口部71od(突出部52d)は隣り合う開口部71oとは45°以外の角度位置に設けられ、第一の摩擦部材71Dを裏返して第一の回転部材50に組付けた場合に誤組み付けができないようにしている。この場合、円柱状となった突出部52の中心がそれぞれ外周延長線上の位置となる様にしている。本実施形態では、複数の開口部71o,71odによって、複数の第二の位置決め部40Dが構成されている。   That is, in the present embodiment, for example, as shown in FIG. 4, the first friction member 71D will be described as an example. The first friction member 71D is provided with a plurality of openings 71o and 71od corresponding to the positions of the plurality of protrusions 52 and 52d provided on the first rotating member 50. The openings 71o and 71od are configured, for example, as semicircular cutouts provided at the peripheral edge (inner peripheral edge) of the first friction member 71D. The openings 71o and 71od are provided on the inner peripheral edge (inner peripheral edge) of the first friction member 71D in an annular shape, and are recessed in a semicircular shape toward the outer side in the radial direction. In the openings 71o and 71od, at least a part of the projecting portion 52, for example, a half region is accommodated. The positions where the openings 71o (similarly the protrusions 52) are provided are regularly provided at seven (45 ° intervals) in the circumferential direction with respect to the rotation center Ax, and the openings 71od (projections 52d) are The adjacent opening 71o is provided at an angular position other than 45 ° so that when the first friction member 71D is turned upside down and assembled to the first rotating member 50, incorrect assembly cannot be performed. In this case, the center of the columnar protrusion 52 is positioned on the outer peripheral extension line. In the present embodiment, a plurality of second positioning portions 40D are configured by the plurality of openings 71o and 71od.

本実施形態の突出部52,52dとなる複数の第一の位置決め部30および開口部71o,71odとなる複数の第二の位置決め部40Dの配置は、第1実施形態と同様である。よって、本実施形態によっても、第1実施形態と同様の効果が得られる。また、本実施形態によれば、例えば、開口部71o,71odが第一の摩擦部材71Dの内周部71yに設けられた切欠として構成されているため、第一の摩擦部材71Dの円環状となった径方向の幅が薄くなりやすい。なお、本実施形態では、図1に示す第二の摩擦部材にあっても、第一の摩擦部材71Dと同様に構成されうる。また、本実施形態では、第一の摩擦部材71Dの内周部71yに開口部71o,71odが設けられ、第一の回転部材50に突出部52,52dが設けられた場合を例示したが、第一の摩擦部材71Dに一体で突出部52,52dが設けられ、第一の回転部材50に切欠による開口部71o,71odが設けられる構成であってもよい。   The arrangement of the plurality of first positioning portions 30 to be the protruding portions 52 and 52d and the plurality of second positioning portions 40D to be the opening portions 71o and 71od in the present embodiment is the same as in the first embodiment. Therefore, the present embodiment can provide the same effects as those of the first embodiment. Further, according to the present embodiment, for example, the openings 71o and 71od are configured as cutouts provided in the inner peripheral portion 71y of the first friction member 71D, and therefore the first friction member 71D has an annular shape. The resulting radial width tends to be thin. In the present embodiment, the second friction member shown in FIG. 1 can be configured similarly to the first friction member 71D. Moreover, in this embodiment, although the opening parts 71o and 71od were provided in the inner peripheral part 71y of 1st friction member 71D, and the protrusion parts 52 and 52d were provided in the 1st rotation member 50, it illustrated, The first friction member 71D may be integrally provided with the protrusions 52 and 52d, and the first rotation member 50 may be provided with openings 71o and 71od by notches.

図5に示される実施形態にかかるリミッタ部102は、上記した第1実施形態のリミッタ部102に対して構造および形状が異なるが、第1実施形態と同様の構成に基づく同様の効果が得られる。
<Fourth embodiment>
The limiter unit 102 according to the embodiment shown in FIG. 5 differs in structure and shape from the limiter unit 102 of the first embodiment described above, but the same effect based on the same configuration as the first embodiment can be obtained. .

即ち、本実施形態では、例えば、図5に示されるように、第一の摩擦部材71Fには、第一の回転部材50の突出部54,54dに対応して、複数の開口部71r,71rdが特異な形状にて設けられている点が第1〜第3実施形態と異なる。本実施形態では、突出部54,54d(図1に示す突出部52、52dに対応)および開口部71r,71rdは、一方向(例えば、図5に示す鉛直線の方向)に対して同じ方向に所定角度(例えば、45°)だけ傾斜している。複数の突出部54,54dおよび複数の開口部71r,71rdは、互いに平行である。突出部54,54dは、扁平な直方体状に構成され、開口部71r,71rdは、突出部54,54dが挿入され嵌合する楕円状の長穴として構成されている。開口部71rの設けられる位置(開口部71rの中心位置)は回転中心Axに対して周方向で7つ(45°間隔)で規則的に設けられていると共に、開口部71rd(開口部71rdの中心位置)は隣り合う開口部71r(開口部71rdの中心位置)とは45°以外の角度位置に設けられ、第一の摩擦部材71Fを裏返して第一の回転部材50に組付けた場合に誤組み付けができないようにしている。本実施形態でも、突出部54,54dによって、第一の位置決め部30Bが構成され、開口部71r,71rdによって、第二の位置決め部40Fが構成されている。   That is, in this embodiment, for example, as shown in FIG. 5, the first friction member 71 </ b> F has a plurality of openings 71 r and 71 rd corresponding to the protrusions 54 and 54 d of the first rotating member 50. Is different from the first to third embodiments in that it is provided in a unique shape. In the present embodiment, the protrusions 54 and 54d (corresponding to the protrusions 52 and 52d shown in FIG. 1) and the openings 71r and 71rd are the same in one direction (for example, the direction of the vertical line shown in FIG. 5). Is inclined by a predetermined angle (for example, 45 °). The plurality of protrusions 54 and 54d and the plurality of openings 71r and 71rd are parallel to each other. The protrusions 54 and 54d are configured in a flat rectangular parallelepiped shape, and the openings 71r and 71rd are configured as elliptical long holes into which the protrusions 54 and 54d are inserted and fitted. The positions where the openings 71r are provided (center positions of the openings 71r) are regularly provided at seven (45 ° intervals) in the circumferential direction with respect to the rotation center Ax, and the openings 71rd (of the openings 71rd). The center position) is provided at an angular position other than 45 ° from the adjacent opening 71r (center position of the opening 71rd), and the first friction member 71F is turned over and assembled to the first rotating member 50. It prevents mis-assembly. Also in the present embodiment, the first positioning portion 30B is configured by the protrusions 54 and 54d, and the second positioning portion 40F is configured by the openings 71r and 71rd.

本実施形態では、複数の第一の位置決め部30Bおよび複数の第二の位置決め部40Fは一方向、例えば、鉛直方向に対してすべて同じ方向に傾斜し、また、一定間隔から外れて配置された突出部54dおよび開口部71rdが設けられているため、複数の第一の位置決め部30Bおよび複数の第二の位置決め部40Fは、双方とも、回転中心Axを通る任意の角度の(全ての)仮想直線Pについて、線対称とならない。よって、本実施形態でも、所期の姿勢から裏返された姿勢や、所期の姿勢から周方向にずれた姿勢では、全ての開口部71r,71rdと全ての突出部54,54dとを位置合わせすることができなくなり、第一の摩擦部材71Fの組み付けは不可となる。したがって、本実施形態によっても、所定の姿勢以外の姿勢での組み付け、すなわち誤組み付けが、抑制される。なお、本実施形態では、図1に示す第二の摩擦部材72に関しても、第一の摩擦部材71Fと同様に構成されうる。   In the present embodiment, the plurality of first positioning portions 30B and the plurality of second positioning portions 40F are inclined in one direction, for example, all in the same direction with respect to the vertical direction, and are arranged out of a fixed interval. Since the protrusion 54d and the opening 71rd are provided, the plurality of first positioning portions 30B and the plurality of second positioning portions 40F are both (all) virtual at any angle passing through the rotation center Ax. The straight line P is not line symmetric. Therefore, also in this embodiment, all the openings 71r and 71rd and all the protrusions 54 and 54d are aligned in a posture reversed from the intended posture or in a posture shifted in the circumferential direction from the intended posture. The first friction member 71F cannot be assembled. Therefore, also in this embodiment, assembly in a posture other than the predetermined posture, that is, erroneous assembly is suppressed. In the present embodiment, the second friction member 72 shown in FIG. 1 can be configured similarly to the first friction member 71F.

<第5実施形態>
図6に示される実施形態にかかるリミッタ部102は、第1実施形態のリミッタ部102の第一の摩擦部材71(第二の摩擦部材72)が円環状であるのに対し、周方向において複数(例えば、四つ)に分割し,開口部71a,71dが分割された1枚毎のプレートに設けられている構成が異なり、本実施形態においても、第1実施形態と同様の構成に基づく同様の効果が得られる。
<Fifth Embodiment>
The limiter unit 102 according to the embodiment shown in FIG. 6 includes a first friction member 71 (second friction member 72) of the limiter unit 102 of the first embodiment having an annular shape, and a plurality of limiter units 102 in the circumferential direction. The configuration provided in each plate divided into four (for example, four) and the openings 71a and 71d are different, and this embodiment is also based on the same configuration as the first embodiment. The effect is obtained.

即ち、本実施形態では、図6に示されるように、複数(一例では、四つ)の同一形状(同一仕様、同一部品)の第一の摩擦部材71Aが、周方向に四つ組み合わせ、組み付け後に全体として円環状となるように並んでいる。図6では、説明上、周方向で隣り合う第一の摩擦部材71同士の間を誇張して離して記載しているが、実際には大きな隙間は存在せず、第一の摩擦部材71Aは、組み合わされて全体として環状となるように構成されている。また、第一の摩擦部材71Aには、第一の回転部材50の突出部52の位置に対応した位置に、それぞれ、複数の開口部71a,71dが設けられている。開口部71aは、例えば、第一の摩擦部材71Aを貫通する貫通孔として構成されている。開口部71dは、例えば、第一の摩擦部材71Aの周方向の端部(90°の位置)で径方向に延びる周縁部の径方向の幅の中央を中心として、径方向の幅の1/3程度の径を有する切欠が、周方向の両端に形成されている。開口部71dは、第一の摩擦部材71Aの周方向の90°毎の両端部に設けられ、周方向の中央に対して半円状に凹んでいる。開口部71a、ならびに周方向で隣接して対向する二つの開口部71d,71d(切欠)の間に、第1実施形態で上述した第一の回転部材50の突出部52が挿入される。本実施形態では、開口部71dの分割された縁部によって、第二の位置決め部40Aが構成されている点で、第1実施形態と異なる。   That is, in this embodiment, as shown in FIG. 6, a plurality (four in one example) of first friction members 71A having the same shape (same specifications and same parts) are combined and assembled in the circumferential direction. They are lined up to form an annular shape as a whole. In FIG. 6, for the sake of explanation, the first friction members 71 adjacent in the circumferential direction are exaggerated and separated from each other, but actually there is no large gap, and the first friction member 71A is Are combined to form an annular shape as a whole. The first friction member 71A is provided with a plurality of openings 71a and 71d at positions corresponding to the positions of the protrusions 52 of the first rotating member 50, respectively. The opening 71a is configured as, for example, a through hole that penetrates the first friction member 71A. The opening 71d is, for example, 1 / of the radial width around the center of the radial width of the peripheral edge extending in the radial direction at the circumferential end (90 ° position) of the first friction member 71A. Notches having a diameter of about 3 are formed at both ends in the circumferential direction. The openings 71d are provided at both ends of the first friction member 71A in the circumferential direction every 90 °, and are recessed in a semicircular shape with respect to the center in the circumferential direction. The protrusion 52 of the first rotating member 50 described above in the first embodiment is inserted between the opening 71a and the two openings 71d and 71d (notches) facing each other in the circumferential direction. This embodiment is different from the first embodiment in that the second positioning portion 40A is configured by the divided edges of the opening 71d.

本実施形態では、図2に例示される第1実施形態の第一の摩擦部材71を、回転中心Axを通る仮想直線、例えば、図2においては水平線および鉛直線の2本の仮想直線によって、四つに分割された構成にしている。このため、本実施形態でも、所期の姿勢から周方向にずれた姿勢や、所期の姿勢から裏返された姿勢では、全ての開口部71a,71dを突出部52に対して位置合わせすることができない。したがって、本実施形態によっても、所定の姿勢以外の姿勢での組み付け、すなわち誤組み付けが、図1に示す摩擦部材71を複数に分割するという簡単な構成で確実に抑制される。   In the present embodiment, the first friction member 71 of the first embodiment illustrated in FIG. 2 is represented by an imaginary straight line passing through the rotation center Ax, for example, two imaginary straight lines in FIG. The structure is divided into four parts. For this reason, also in the present embodiment, all the openings 71a and 71d are aligned with the protrusions 52 in a posture deviated from the intended posture in the circumferential direction or in a posture reversed from the intended posture. I can't. Therefore, also in this embodiment, assembly in a posture other than the predetermined posture, that is, erroneous assembly is reliably suppressed with a simple configuration in which the friction member 71 shown in FIG. 1 is divided into a plurality of parts.

本実施形態では、周方向に互いに対向する開口部71d,71d(切欠に形成)の間に、第一の回転部材50の突出部52が挿入されている。これによって、例えば、第一の位置決め部30となる突出部52の製造ばらつきや寸法ばらつきが吸収されやすい。よって、例えば、第一の位置決め部30と第二の位置決め部40,40Aとの位置合わせが、より容易に、より円滑に、あるいはより精度よく行われやすい。なお、本実施形態では、第一の摩擦部材71Aは、例えば、接着剤等によって、第一の回転部材50と一体化して固定しても良い。また、本実施形態では、第二の摩擦部材(本実施形態では図示されず、図1参照)にあっても、第一の摩擦部材71Aと同様に第三の回転部材80等に一体化して固定することも可能である。   In the present embodiment, the protrusion 52 of the first rotating member 50 is inserted between the openings 71d and 71d (formed in the notch) that are opposed to each other in the circumferential direction. As a result, for example, manufacturing variations and dimensional variations of the protrusion 52 serving as the first positioning unit 30 are easily absorbed. Therefore, for example, the alignment between the first positioning portion 30 and the second positioning portions 40, 40A is easily performed more smoothly or more accurately. In the present embodiment, the first friction member 71A may be fixed integrally with the first rotating member 50 by, for example, an adhesive. Further, in the present embodiment, even in the second friction member (not shown in the present embodiment, see FIG. 1), it is integrated with the third rotating member 80 and the like in the same manner as the first friction member 71A. It is also possible to fix.

<第6実施形態>
図7に示される本実施形態にかかるリミッタ部102は、上述した第1実施形態の構成を基礎とした第5実施形態の変形例である。よって、本実施形態によっても、上記第1実施形態と同様の構成に基づく同様の効果が得られる。
<Sixth Embodiment>
A limiter unit 102 according to the present embodiment shown in FIG. 7 is a modification of the fifth embodiment based on the configuration of the first embodiment described above. Therefore, according to this embodiment, the same effect based on the same configuration as that of the first embodiment can be obtained.

即ち、本実施形態でも、図7に示されるように、複数(例えば四つ)の同一形状(同一仕様、同一部品)の第一の摩擦部材71Bが周方向に並び、第一の摩擦部材71Bは、組み合わされて全体として円環状(分割円環状)に構成されている。ただし、本実施形態では、図7に例示されるように、第一の回転部材50には、互いに形状が異なる少なくとも二種類の突出部52,53が設けられている。具体的には、例えば、図7に示されるように突出部53の一平面での径の面積(直径、開口幅)は、突出部52の径の面積(直径、開口幅)よりも小さく構成されている。そして、第一の摩擦部材71Bには、突出部52,53に対応した位置に互いに形状が異なる少なくとも二種類の開口部71a,71mがそれぞれ設けられている。すなわち、突出部52の設けられる位置に対応して、突出部52が挿入可能な開口部71aが設けられ、同様にして突出部53の設けられる位置に対応して、突出部53を挿入可能な開口部71mが設けられている。そして、開口部71mの一平面での面積(直径、開口幅)は、突出部52の面積(直径、開口幅)よりも小さく構成されている。すなわち、開口部71mは突出部52を挿入できない程、小さく構成されている。本実施形態では、全体として複数の突出部52,53によって複数の第一の位置決め部30Aが構成され、複数の開口部71a,71mの縁部によって複数の第二の位置決め部40Bが構成されている。この場合、突出部52、53の位置に対応して、突出部52、53が中に挿入される開口部71a,71mは、それぞれ分割された1枚のプレート毎に設けられると良い。   That is, also in this embodiment, as shown in FIG. 7, a plurality of (for example, four) first friction members 71B having the same shape (same specifications and same parts) are arranged in the circumferential direction, and the first friction members 71B are arranged. Are combined to form an annular shape (divided annular shape) as a whole. However, in this embodiment, as illustrated in FIG. 7, the first rotating member 50 is provided with at least two types of protrusions 52 and 53 having different shapes. Specifically, for example, as shown in FIG. 7, the area (diameter, opening width) of the diameter of the protrusion 53 on one plane is configured to be smaller than the area of the diameter (diameter, opening width) of the protrusion 52. Has been. The first friction member 71B is provided with at least two types of openings 71a and 71m having different shapes from each other at positions corresponding to the protrusions 52 and 53, respectively. That is, an opening 71a into which the protrusion 52 can be inserted is provided corresponding to the position where the protrusion 52 is provided, and similarly, the protrusion 53 can be inserted corresponding to the position where the protrusion 53 is provided. An opening 71m is provided. And the area (diameter, opening width) in one plane of the opening part 71m is comprised smaller than the area (diameter, opening width) of the protrusion part 52. FIG. That is, the opening 71m is configured to be so small that the protrusion 52 cannot be inserted. In the present embodiment, a plurality of first positioning portions 30A are constituted by the plurality of protrusions 52, 53 as a whole, and a plurality of second positioning portions 40B are constituted by the edges of the plurality of openings 71a, 71m. Yes. In this case, the openings 71a and 71m into which the protrusions 52 and 53 are inserted are preferably provided for each of the divided plates corresponding to the positions of the protrusions 52 and 53.

本実施形態では、複数の突出部52,53の配置および形状により、複数の第一の位置決め部30Aは、回転中心Axを通る任意の仮想直線Pについて、線対称ではない。また、第一の摩擦部材71Bでは、複数の開口部71a,71mの配置および形状により、複数の第二の位置決め部40Bは、回転中心Axを通る任意の仮想直線Pについて、線対称ではない。よって、本実施形態でも、所期の姿勢から裏返された姿勢や、所期の姿勢から周方向にずれた姿勢では、全ての開口部71a,71mと全ての突出部52,53とを位置合わせして組み付けすることができない。したがって、本実施形態によっても、所定の姿勢以外の姿勢での組み付け、すなわち誤組み付けが、抑制される。   In the present embodiment, due to the arrangement and shape of the plurality of protrusions 52 and 53, the plurality of first positioning portions 30A are not line symmetric with respect to an arbitrary virtual straight line P passing through the rotation center Ax. In the first friction member 71B, due to the arrangement and shape of the plurality of openings 71a and 71m, the plurality of second positioning portions 40B are not line symmetric with respect to an arbitrary virtual straight line P passing through the rotation center Ax. Therefore, also in this embodiment, in the posture reversed from the intended posture or the posture shifted in the circumferential direction from the intended posture, all the openings 71a and 71m and all the protruding portions 52 and 53 are aligned. Cannot be assembled. Therefore, also in this embodiment, assembly in a posture other than the predetermined posture, that is, erroneous assembly is suppressed.

また、本実施形態によれば、例えば、二つの第一の位置決め部30A(突出部52,53)の形状差、ならびに二つの第二の位置決め部40B(開口部71a,71m)の形状差によって、仮に正しくない姿勢で配置されたとしても、突出部52の開口部71mへの挿入、すなわち誤組み付けが、抑制される。なお、本実施形態でも、図1に示す第二の摩擦部材72にあっても、図7の第一の摩擦部材71Bと同様に構成されうる。   Further, according to the present embodiment, for example, due to the difference in shape between the two first positioning portions 30A (projections 52 and 53) and the difference in shape between the two second positioning portions 40B (openings 71a and 71m). Even if it is disposed in an incorrect posture, insertion of the protrusion 52 into the opening 71m, that is, erroneous assembly is suppressed. In the present embodiment, the second friction member 72 shown in FIG. 1 can be configured similarly to the first friction member 71B in FIG.

<第7実施形態>
図8に示される実施形態にかかるリミッタ部102は、上記した第1実施形態のリミッタ部102と同様の構成を備え、一部摩擦部材の形状が異なっており、本実施形態によっても、上記第1実施形態と同様の構成に基づく同様の効果が得られる。
<Seventh embodiment>
The limiter unit 102 according to the embodiment shown in FIG. 8 has the same configuration as the limiter unit 102 of the first embodiment described above, and a part of the friction member has a different shape. The same effect based on the same configuration as that of the first embodiment can be obtained.

即ち、本実施形態では、例えば、図8に示されるように、第一の摩擦部材71Eには、第一の回転部材50の複数の突出部52の設けられる位置に対応して、第一の開口部となる複数の開口部71pが設けられている。開口部71pは、第一の回転部材50側に向けて開口された凹部として構成されている。また、第一の摩擦部材71Eの開口部71pとは反対側に、それぞれの開口部71pの設けられる位置に対応して、第二の開口部となる複数の開口部71qが設けられている。開口部71qは、軸方向の第三の回転部材80側に向けて開口された凹部として構成されている。この構成において、開口部71qの断面の径(直径、開口幅)は、突出部52の断面の径(直径、開口幅)よりも小さく構成され、開口部71pと開口部71qとが、軸方向に貫通した状態で連通している。本実施形態では、開口部71pの縁部によって、第二の位置決め部40Eが構成されている。よって、本実施形態によれば、例えば、第一の摩擦部材71Eが裏返しの状態では、開口部71p,71qの径の大きさの違いにより、突出部52は開口部71q内には進入できず、組み付け不可となる。したがって、本実施形態によっても、所定の姿勢以外の姿勢での組み付け、すなわち、第一の摩擦部材71Eの誤組み付けが、抑制される。また、本実施形態によれば、例えば、第一の摩擦部材71Eを第一の回転部材50に組み付ける際に、開口部71qの径の大きさを通じて突出部52を組み付けが可能か否かを容易に視認することができる。よって、本実施形態によれば、例えば、位置合わせの作業がより容易にあるいはより精度良く行われやすい。なお、本実施形態では、第二の摩擦部材72Eも、第一の摩擦部材71Eと同様に構成されうる。また、本実施形態では、第一の摩擦部材71Eに開口部71p,71qが設けられ、第一の回転部材50に突出部52が設けられた場合を例示したが、第一の摩擦部材71Eに突出部52が設けられ、第一の回転部材50に開口部71p,71qが設けられる構成であってもよい。また、この構成は、円環状または分割円環状の第一の摩擦部材71および第二の摩擦部材72にも適用が可能である。   That is, in the present embodiment, for example, as shown in FIG. 8, the first friction member 71 </ b> E corresponds to the positions where the plurality of protrusions 52 of the first rotating member 50 are provided. A plurality of openings 71p serving as openings are provided. The opening 71p is configured as a recess opened toward the first rotating member 50 side. A plurality of openings 71q serving as second openings are provided on the opposite side of the first friction member 71E from the openings 71p, corresponding to the positions where the respective openings 71p are provided. The opening 71q is configured as a recess opened toward the third rotating member 80 side in the axial direction. In this configuration, the diameter (diameter, opening width) of the cross section of the opening 71q is configured to be smaller than the diameter (diameter, opening width) of the cross section of the protrusion 52, and the opening 71p and the opening 71q are in the axial direction. It communicates in a state of penetrating into the. In the present embodiment, the second positioning portion 40E is configured by the edge of the opening 71p. Therefore, according to the present embodiment, for example, when the first friction member 71E is turned upside down, the protrusion 52 cannot enter the opening 71q due to the difference in diameter between the openings 71p and 71q. Assembling is impossible. Therefore, also in this embodiment, assembly in a posture other than the predetermined posture, that is, erroneous assembly of the first friction member 71E is suppressed. Further, according to the present embodiment, for example, when the first friction member 71E is assembled to the first rotating member 50, it is easy to determine whether the protrusion 52 can be assembled through the size of the diameter of the opening 71q. Can be visually recognized. Therefore, according to the present embodiment, for example, the alignment operation is easily performed with higher accuracy. In the present embodiment, the second friction member 72E can be configured similarly to the first friction member 71E. In the present embodiment, the first friction member 71E is provided with the openings 71p and 71q, and the first rotation member 50 is provided with the protrusion 52. However, the first friction member 71E includes the first friction member 71E. The protrusion 52 may be provided, and the first rotating member 50 may be provided with the openings 71p and 71q. This configuration can also be applied to the first friction member 71 and the second friction member 72 that are annular or split annular.

<第8実施形態>
図9に示される本実施形態にかかるリミッタ部102は、上記した第1実施形態のリミッタ部102の基本的な構成は同じで、第一の摩擦部材71G(第二の摩擦部材72G)を位置決めする形状が異なり、本実施形態によっても、第1実施形態と同様の構成に基づく同様の効果が得られる。
<Eighth Embodiment>
The limiter unit 102 according to the present embodiment shown in FIG. 9 has the same basic configuration as the limiter unit 102 of the first embodiment described above, and positions the first friction member 71G (second friction member 72G). The shapes to be obtained are different, and the same effect based on the same configuration as that of the first embodiment can be obtained by this embodiment.

即ち、本実施形態では、例えば、図9に示されるように、第一の回転部材50に、複数の開口部55が設けられ、第一の摩擦部材71G側に、第一の回転部材50の突出部55の設けられる位置に対応して、複数の突出部71sが第一の摩擦部材71Gと一体で設けられている。突出部71sは、第一の摩擦部材71Gの第二の回転部材60とは反対側の第二の面71cから第一の回転部材50側に向けて突出している。本実施形態では、開口部55によって、第一の位置決め部30Cが構成され、突出部71sによって、第二の位置決め部40Gが構成されている。よって、本実施形態によれば、例えば、第一の摩擦部材71Fに設けられた突出部71sによって、摩擦面となる第一の面71bと摩擦面の裏側の第二の面71cとが側面形状を見るだけで、瞬時にして簡単に特定されやすい。よって、例えば、第一の摩擦部材71Fの表裏の誤組み付けが、より一層抑制されやすい。なお、本実施形態では、第二の摩擦部材72Gも、第一の摩擦部材71Gと同様に構成されうる。また、この構成は、円環状または分割円環状の第一の摩擦部材71および第二の摩擦部材72にも適用が可能である。   That is, in the present embodiment, for example, as shown in FIG. 9, a plurality of openings 55 are provided in the first rotating member 50, and the first rotating member 50 is disposed on the first friction member 71 </ b> G side. Corresponding to the position where the protrusion 55 is provided, a plurality of protrusions 71s are provided integrally with the first friction member 71G. The protrusion 71s protrudes from the second surface 71c of the first friction member 71G opposite to the second rotation member 60 toward the first rotation member 50. In the present embodiment, the opening 55 constitutes the first positioning portion 30C, and the protrusion 71s constitutes the second positioning portion 40G. Therefore, according to the present embodiment, for example, the first surface 71b serving as the friction surface and the second surface 71c on the back side of the friction surface are formed in a side surface shape by the protrusion 71s provided on the first friction member 71F. It is easy to identify instantly and simply by looking. Therefore, for example, erroneous assembly of the front and back of the first friction member 71F can be further suppressed. In the present embodiment, the second friction member 72G can be configured similarly to the first friction member 71G. This configuration can also be applied to the first friction member 71 and the second friction member 72 that are annular or split annular.

図10に示される本実施形態にかかるリミッタ部102は、第1実施形態のリミッタ部102の第一の摩擦部材71Hおよび第二の摩擦部材72Hの形状が異なり、それ以外は第1実施形態と同様の構成を備えている。よって、本実施形態によっても、上記第1実施形態と同様の構成に基づく同様の効果が得られる。
<Ninth Embodiment>
The limiter unit 102 according to the present embodiment shown in FIG. 10 is different from the first embodiment in the shapes of the first friction member 71H and the second friction member 72H of the limiter unit 102 of the first embodiment. It has the same configuration. Therefore, according to this embodiment, the same effect based on the same configuration as that of the first embodiment can be obtained.

即ち、本実施形態では、例えば、図10に示されるように、第一の摩擦部材71Hに、第一の回転部材50に設けられた突出部52に対応して、複数の開口部71tが設けられている。開口部71tは、第一の回転部材50側に向けて開口された凹部として構成されている。本実施形態では、開口部71tによって、貫通していない第二の位置決め部40Hが構成されている。よって、本実施形態によれば、例えば、第一の摩擦部材71Hに設けられた貫通していない凹部状の開口部71tによって、摩擦面となる第一の面71bと摩擦面の裏側の第二の面71cとが側面形状を見るだけで、瞬時にして簡単に特定されやすい。よって、例えば、第一の摩擦部材71Hの表裏の誤組み付けが、より一層抑制されやすい。なお、本実施形態では、第二の摩擦部材72Hも、第一の摩擦部材71Hと同様に構成されうる。この構成も同様に、円環状または分割円環状の第一の摩擦部材71および第二の摩擦部材72にも適用が可能である。   That is, in the present embodiment, for example, as shown in FIG. 10, the first friction member 71 </ b> H is provided with a plurality of openings 71 t corresponding to the protrusions 52 provided on the first rotating member 50. It has been. The opening 71t is configured as a recess opened toward the first rotating member 50 side. In the present embodiment, the opening 71t constitutes the second positioning portion 40H that does not penetrate. Therefore, according to the present embodiment, for example, the first surface 71b serving as the friction surface and the second on the back side of the friction surface are formed by the non-penetrating recessed opening portion 71t provided in the first friction member 71H. By simply looking at the side surface shape of the surface 71c, it can be easily specified instantly. Therefore, for example, erroneous assembly of the front and back surfaces of the first friction member 71H can be further suppressed. In the present embodiment, the second friction member 72H can be configured similarly to the first friction member 71H. Similarly, this configuration can also be applied to the first friction member 71 and the second friction member 72 having an annular shape or a split annular shape.

<第10実施形態>
図11に示される実施形態にかかるリミッタ部は、上記した第1実施形態のリミッタ部102の構成は異なるが、第1実施形態と同様の構成を備えている。よって、本実施形態によっても、上記第1実施形態と同様の構成に基づく同様の効果が得られる。
<Tenth Embodiment>
The limiter unit according to the embodiment shown in FIG. 11 has the same configuration as that of the first embodiment, although the configuration of the limiter unit 102 of the first embodiment described above is different. Therefore, according to this embodiment, the same effect based on the same configuration as that of the first embodiment can be obtained.

即ち、本実施形態では、例えば、図11に示されるように、第一の摩擦部材71Iおよび第二の摩擦部材72Iが設けられる第一の回転部材50および第三の回転部材80の位置を段状とし、軸方向の他方側に向けて凹んだ凹部56が第二の回転部材60が位置する内側に設けられ、第一の摩擦部材71Iに、第一の回転部材50の凹部56の設けられる位置に対応して、突出部71uが設けられている。よって、本実施形態によれば、例えば、第一の摩擦部材71Iに一体で設けられた突出部71uによって、摩擦面として機能する第一の面71bと摩擦面に対して裏側の第二の面71cとが形状を見るだけで容易に特定されやすい。よって、例えば、第一の摩擦部材71Iの表裏の誤組み付けが、より一層抑制されやすい。なお、本実施形態では、段状となった凹部56ならびに突出部71uは、円環状に構成されうる。また、第二の摩擦部材72Iも、第一の摩擦部材71Iと同様に構成されうる。この構成も同様に、円環状または分割円環状の第一の摩擦部材71および第二の摩擦部材72にも適用が可能である。   That is, in this embodiment, for example, as shown in FIG. 11, the positions of the first rotating member 50 and the third rotating member 80 provided with the first friction member 71I and the second friction member 72I are stepped. A concave portion 56 that is recessed toward the other side in the axial direction is provided on the inner side where the second rotating member 60 is located, and the concave portion 56 of the first rotating member 50 is provided in the first friction member 71I. Corresponding to the position, a protrusion 71u is provided. Therefore, according to the present embodiment, for example, the first surface 71b functioning as the friction surface and the second surface on the back side with respect to the friction surface by the protruding portion 71u provided integrally with the first friction member 71I. 71c is easily identified simply by looking at the shape. Therefore, for example, erroneous assembly of the front and back surfaces of the first friction member 71I can be further suppressed. In the present embodiment, the stepped concave portion 56 and the protruding portion 71u can be configured in an annular shape. Also, the second friction member 72I can be configured similarly to the first friction member 71I. Similarly, this configuration can also be applied to the first friction member 71 and the second friction member 72 having an annular shape or a split annular shape.

For example, the first friction member 71 (second friction member 72) includes a plurality of regular openings 71a provided at equal intervals in the circumferential direction with respect to the rotation center Ax, and the openings 71a. There are non-regular openings 71ad provided at positions that are not equally spaced, and these become the second positioning portions. Further, for example, the center of the first positioning portion is positioned on the outer peripheral portion 71x or the inner peripheral portion 71y of the first friction member 71 (second friction member 72) having an annular shape. In addition, for example, by arranging a plurality of divided annular first friction members 71 (second friction members 72) in the circumferential direction, adjacent first friction members (second friction members) around A peripheral end opening 71d is formed by the end in the direction, and an intermediate opening 71a is provided between the peripheral end openings 71d.
