第１部材２０は、軸線Ｏを中心とする円板状に形成された本体２１と、本体２１の外周に配置される円筒状の突部２３と、を備えている。突部２３は本体２１と一体に形成され、第２部材４０と反対側の軸線Ｏ方向へ延びている。本体２１は輪状に形成され、本体２１の内周面にスプライン２２が形成されている。 The first member 20 includes a main body 21 formed in a disk shape centered on the axis O, and a cylindrical protrusion 23 arranged on the outer periphery of the main body 21. The protrusion 23 is formed integrally with the main body 21 and extends in the axis O direction opposite to the second member 40. The main body 21 is formed in a ring shape, and a spline 22 is formed on the inner peripheral surface of the main body 21.

第１部材２０は、軸線Ｏに交差する（本実施形態では軸線Ｏに直交する）平坦面状の第１面２４に第１穴２５，２６（図４参照）が形成されている。第１面２４は、第２部材４０の第２面４２と軸線Ｏ方向に対向している。第１穴２５，２６は、本体２１を軸線Ｏ方向に貫通する。第１穴２５，２６には、第２部材４０側を向く第３面２７，２８（図４参照）がそれぞれ形成されている。第１穴２５には圧縮ばね５０が収納され、第３面２７には第１係合子５１が配置される。 The first member 20 has first holes 25 and 26 (see FIG. 4) formed on a flat first surface 24 that intersects the axis O (in this embodiment, is orthogonal to the axis O). The first surface 24 faces the second surface 42 of the second member 40 in the O direction of the axis. The first holes 25 and 26 penetrate the main body 21 in the O direction of the axis. The first holes 25 and 26 are formed with third surfaces 27 and 28 (see FIG. 4) facing the second member 40 side, respectively.

図４に示すように第１部材２０は、第１部材２０の周方向の長さが異なる第１穴２５，２６が周方向に交互に並んでいる。第１穴２５，２６は軸線Ｏ方向から見て略矩形状である。第１穴２５，２６には、軸線Ｏ方向を向く第３面２７，２８が穴の全周に形成されている。第３面２８の第１部材２０の周方向における長さは、第３面２７の第１部材２０の周方向における長さよりも長い。第１凹部２９は第１穴２５に連なり径方向の両側へ延びる窪みである。第１凹部３０は第１穴２６に連なり径方向の両側へ延びる窪みである。 As shown in FIG. 4, in the first member 20, first holes 25 and 26 having different lengths in the circumferential direction of the first member 20 are alternately arranged in the circumferential direction. The first holes 25 and 26 have a substantially rectangular shape when viewed from the axis O direction. In the first holes 25 and 26, third surfaces 27 and 28 facing the axis O direction are formed on the entire circumference of the holes. The length of the first member 20 of the third surface 28 in the circumferential direction is longer than the length of the first member 20 of the third surface 27 in the circumferential direction. The first recess 29 is a recess that is connected to the first hole 25 and extends to both sides in the radial direction. The first recess 30 is a recess that is connected to the first hole 26 and extends to both sides in the radial direction.

The arm 53 of the first engaging element 51 (see FIG. 6) is arranged in the first recess 29, and the edge portion of the support column 52 of the first engaging element 51 is arranged in the third surface 27. Similarly, the second engaging element 54 (see FIG. 6) is arranged in the first recess 30 and the third surface 28. Since the circumferential length of the first hole 26 and the first recess 30 is longer than the circumferential length of the second engager 54, the second engager 54 is in the plane of the first recess 30 and the third surface 28. Can be slid.

第１部材２０は、第１穴２５，２６を周方向に繋ぐ第２凹部３１が第１面２４に形成されている。第２凹部３１は、第２部材４０（図１参照）に配置されたリング４６が進入する環状の窪みである。第１部材２０は、第２凹部３１の径方向の内側に、軸線Ｏ方向に貫通するピン穴３２が複数形成されている。ピン穴３２はピン５６（図３参照）が嵌合する穴である。ピン５６は、第１部材２０のピン穴３２と共に、第３部材６０を貫通するピン穴６３にも嵌合し、第１部材２０に対する第３部材６０の相対回転を規制する。第３部材６０は、油穴６１の位置を第１穴２５，２６の位置に一致させて、第１部材２０に固定される。油穴６１の大きさは第１穴２５，２６の大きさよりも小さい。 In the first member 20, a second recess 31 connecting the first holes 25 and 26 in the circumferential direction is formed on the first surface 24. The second recess 31 is an annular recess into which the ring 46 arranged in the second member 40 (see FIG. 1) enters. The first member 20 is formed with a plurality of pin holes 32 penetrating in the axis O direction inside the second recess 31 in the radial direction. The pin hole 32 is a hole into which the pin 56 (see FIG. 3) is fitted. The pin 56 fits into the pin hole 63 penetrating the third member 60 together with the pin hole 32 of the first member 20, and regulates the relative rotation of the third member 60 with respect to the first member 20. The third member 60 is fixed to the first member 20 by matching the position of the oil hole 61 with the positions of the first holes 25 and 26. The size of the oil hole 61 is smaller than the size of the first holes 25 and 26.

図５（ａ）は図４のＶａ－Ｖａ線における第１部材２０及び第３部材６０の断面図であり、図５（ｂ）は第２係合子５４及び圧縮ばね５０が配置された第１部材２０及び第３部材６０の断面図である。第２係合子５４は、第２部材４０（図１参照）の第２面４２と第１部材２０の第３面２８との間に配置される。圧縮ばね５０は、第２係合子５４と第３部材６０との間に配置され、第２係合子５４の支柱５２の、腕５３と反対側の部分に腕５３を支点に弾性力を加える。腕５３は第２部材４０の第２面４２に押さえられるので、リング４６が第２部材４０側へ後退すると、第２係合子５４は、支柱５２の腕５３と反対側の部分が圧縮ばね５０のばね力により第２部材４０側へ起き上がる。第１係合子５１（図６参照）も同様である。 5 (a) is a cross-sectional view of the first member 20 and the third member 60 in the Va-Va line of FIG. 4, and FIG. 5 (b) is a first view in which the second engager 54 and the compression spring 50 are arranged. It is sectional drawing of the member 20 and the third member 60. The second engaging element 54 is arranged between the second surface 42 of the second member 40 (see FIG. 1) and the third surface 28 of the first member 20. The compression spring 50 is arranged between the second engaging element 54 and the third member 60, and applies an elastic force to the portion of the support column 52 of the second engaging element 54 opposite to the arm 53 with the arm 53 as a fulcrum. Since the arm 53 is pressed by the second surface 42 of the second member 40, when the ring 46 retracts to the second member 40 side, the portion of the second engager 54 opposite to the arm 53 of the support column 52 is a compression spring 50. It rises to the side of the second member 40 by the spring force of. The same applies to the first engaging element 51 (see FIG. 6).

The third recess 33 is a recess in which a retainer 65 (see FIG. 6) that regulates the rise of the first engaging element 51 is arranged. The fourth recess 34 is a recess in which a compression spring (not shown) for urging the retainer 65 in the first direction (arrow F direction) is arranged. The retainer 65 moves in the circumferential direction through the third recess 33.

図６は第１係合子５１、第２係合子５４及びリテーナ６５が配置された第１部材２０の正面図である。圧縮ばね（図示せず）の弾性力によって第１方向（矢印Ｆ方向）へ付勢されたリテーナ６５は、第２係合子５４を第１方向（矢印Ｆ方向）へスライドさせ、同時に第１係合子５１の一部を覆う。これによりリテーナ６５は、圧縮ばね５０（図３参照）の弾性力による第１係合子５１の起き上がりを阻止する。 FIG. 6 is a front view of the first member 20 in which the first engaging element 51, the second engaging element 54, and the retainer 65 are arranged. The retainer 65 urged in the first direction (arrow F direction) by the elastic force of the compression spring (not shown) slides the second engager 54 in the first direction (arrow F direction), and at the same time, the first engagement. Covers a part of the joint 51. As a result, the retainer 65 prevents the first engager 51 from rising due to the elastic force of the compression spring 50 (see FIG. 3).

一方、第２係合子５４はリテーナ６５の位置に関わらず第２部材４０側へ起き上がることができる。第２部材４０に対して第１方向（矢印Ｆ方向）へ第１部材２０が相対回転し、第２係合子５４が第２部材４０の第２穴４３に係合すると、第１部材２０と第２部材４０とは一体に回転しトルクを伝達する。そうすると、第２係合子５４に押されてリテーナ６５は第２方向（反矢印Ｆ方向）へ回転する。その結果、リテーナ６５は第１係合子５１を覆えなくなるので、第１係合子５１は圧縮ばね５０（図３参照）の弾性力によって第２部材４０（図１参照）側へ起き上がることができる。 On the other hand, the second engaging element 54 can rise toward the second member 40 regardless of the position of the retainer 65. When the first member 20 rotates relative to the second member 40 in the first direction (arrow F direction) and the second engaging element 54 engages with the second hole 43 of the second member 40, the first member 20 and the second member 20 It rotates integrally with the second member 40 and transmits torque. Then, the retainer 65 is pushed by the second engaging element 54 and rotates in the second direction (counter-arrow F direction). As a result, the retainer 65 cannot cover the first engaging element 51, so that the first engaging element 51 can rise toward the second member 40 (see FIG. 1) by the elastic force of the compression spring 50 (see FIG. 3).

第２部材４０側へ起き上がった第１係合子５１は、第２部材４０に対して第２方向（反矢印Ｆ方向）へ第１部材２０が相対回転すると、第２部材４０の第２穴４３に係合する。これにより、第２部材４０に対して第２方向（反矢印Ｆ方向）へ相対回転する第１部材２０のトルクを第２部材４０に伝達できる。 When the first member 20 rotates relative to the second member 40 in the second direction (counter-arrow F direction), the first engaging element 51 that rises to the second member 40 side causes the second hole 43 of the second member 40. Engage in. As a result, the torque of the first member 20 that rotates relative to the second member 40 in the second direction (counter-arrow F direction) can be transmitted to the second member 40.

２方向クラッチからなるクラッチ装置１０を組み立てるには、まず、第１部材２０の第３面２７に第１係合子５１を配置し、第３面２８に第２係合子５４を配置する。次いで、圧縮ばね（図示せず）を第４凹部３４に配置しながらリテーナ６５を第３凹部３３に配置する。次に、第２凹部３１にリング４６を挿入した後、第１部材２０の第１面２４に第２面４２を突き合わせるように第２部材４０を配置し、第２部材４０のリング溝４４にリング４６を収容する。次いで、第１部材２０の第１穴２５，２６の中に圧縮ばね５０を入れた後、第３部材６０を第１部材２０に接触させ、第１係合子５１及び第２係合子５４と第３部材６０との間に圧縮ばね５０を挟み込む。最後に、留め具６４を溝３６に嵌めて第３部材６０を固定する。このように、第１係合子５１及び第２係合子５４を第３面２７，２８に配置した後に圧縮ばね５０を第１穴２５，２６に配置し、次いで、第３部材６０で第１穴２５，２６を塞ぐことができる。 In order to assemble the clutch device 10 including the two-way clutch, first, the first engaging element 51 is arranged on the third surface 27 of the first member 20, and the second engaging element 54 is arranged on the third surface 28. Next, the retainer 65 is arranged in the third recess 33 while the compression spring (not shown) is arranged in the fourth recess 34. Next, after inserting the ring 46 into the second recess 31, the second member 40 is arranged so that the second surface 42 abuts against the first surface 24 of the first member 20, and the ring groove 44 of the second member 40 is arranged. The ring 46 is housed in. Next, after inserting the compression spring 50 into the first holes 25 and 26 of the first member 20, the third member 60 is brought into contact with the first member 20, and the first engaging element 51 and the second engaging element 54 are brought into contact with each other. The compression spring 50 is sandwiched between the three members 60. Finally, the fastener 64 is fitted into the groove 36 to fix the third member 60. In this way, after the first engaging element 51 and the second engaging element 54 are arranged on the third surfaces 27 and 28, the compression spring 50 is arranged on the first holes 25 and 26, and then the first hole in the third member 60. It can block 25 and 26.

従来は第１部材に第３部材が一体化していた（第１穴が止まり穴であった）ので、クラッチ装置を組み立てるときに、止まり穴の底に圧縮ばね５０を配置した後、第１係合子５１及び第２係合子５４を配置すると、圧縮ばね５０の弾性力で第１係合子５１及び第２係合子５４が浮いた状態になる。そのような状態でリテーナ６５やリング４６を配置するので、リテーナ６５やリング４６も浮いた不安定な状態になる。そのため組立作業性が悪いという問題点があった。 In the past, the third member was integrated with the first member (the first hole was a blind hole), so when assembling the clutch device, after arranging the compression spring 50 at the bottom of the blind hole, the first engagement When the coupling 51 and the second engaging element 54 are arranged, the first engaging element 51 and the second engaging element 54 are in a floating state by the elastic force of the compression spring 50. Since the retainer 65 and the ring 46 are arranged in such a state, the retainer 65 and the ring 46 also become a floating and unstable state. Therefore, there is a problem that the assembly workability is poor.

これに対し本実施形態によれば、第１穴２５，２６が貫通しているので、第１係合子５１及び第２係合子５４が不安定な浮いた状態にならないようにしながら、クラッチ装置１０を組み立てられる。よって、クラッチ装置１０の組立作業性を向上できる。また、第１部材２０の第１穴２５，２６は本体２１を貫通しているので、止まり穴を第１部材に設ける場合に比べ、第１穴２５，２６を第１部材２０に簡易に形成できる。 On the other hand, according to the present embodiment, since the first holes 25 and 26 penetrate the clutch device 10, the clutch device 10 is prevented from the unstable floating state of the first engaging element 51 and the second engaging element 54. Can be assembled. Therefore, the assembly workability of the clutch device 10 can be improved. Further, since the first holes 25 and 26 of the first member 20 penetrate the main body 21, the first holes 25 and 26 are easily formed in the first member 20 as compared with the case where the blind hole is provided in the first member. can.

In FIG. 8, the illustration on one side with the axis O as a boundary and the illustration of the second member 40 are omitted. In this embodiment, the fastener 74 is a snap ring (for a shaft).

第１部材７１は、本体２１の内周に形成されたスプライン２２に係合するスリーブ７２を介して、入力軸１１（図８参照）に結合する。スリーブ７２の外径は、第３部材６０の内周面６２の直径よりも小さい。スリーブ７２の外周面には、周方向に延びる溝７３が形成されている。第１部材７１に第３部材６０を密着させた状態で、留め具７４を溝７３に嵌め、留め具７４を第３部材６０に接触させることにより、第１部材７１に対して第３部材６０が固定される。第１実施形態で説明した第１部材２０（図３参照）の突部２３を省略できるので、第１部材７１を軽量化できる。 The first member 71 is coupled to the input shaft 11 (see FIG. 8) via a sleeve 72 that engages with a spline 22 formed on the inner circumference of the main body 21. The outer diameter of the sleeve 72 is smaller than the diameter of the inner peripheral surface 62 of the third member 60. A groove 73 extending in the circumferential direction is formed on the outer peripheral surface of the sleeve 72. With the third member 60 in close contact with the first member 71, the fastener 74 is fitted into the groove 73, and the fastener 74 is brought into contact with the third member 60 to bring the fastener 74 into contact with the third member 60 so that the third member 60 is relative to the first member 71. Is fixed. Since the protrusion 23 of the first member 20 (see FIG. 3) described in the first embodiment can be omitted, the weight of the first member 71 can be reduced.

In FIG. 10, the illustration on one side with the axis O as a boundary and the illustration of the second member 40 are omitted.

第１部材８１は、第１面２４を有する輪状の第１板部８２と、第３面２７，２８を有する輪状の第２板部８６と、を備えている。第１板部８２は、第１板部８２の周方向の長さが異なる第１穴８３，８４が周方向に交互に並んでいる。第１穴８３，８４は、第１板部８２を軸線Ｏ方向に貫通する。第１穴８３，８４は軸線Ｏ方向から見て略矩形状である。 The first member 81 includes a ring-shaped first plate portion 82 having a first surface 24 and a ring-shaped second plate portion 86 having third surfaces 27 and 28. In the first plate portion 82, first holes 83, 84 having different lengths in the circumferential direction of the first plate portion 82 are alternately arranged in the circumferential direction. The first holes 83 and 84 pass through the first plate portion 82 in the O-direction of the axis. The first holes 83 and 84 have a substantially rectangular shape when viewed from the axis O direction.

第１板部８２は、第１穴８３に連なる第１凹部２９、第１穴８４に連なる第１凹部３０、第２凹部３１、ピン穴３２、第３凹部３３及び第４凹部３４が、第１面２４に形成されている。第１凹部２９，３０、第２凹部３１、ピン穴３２及び第４凹部３４は、第１板部８２を軸線Ｏ方向に貫通する。第１穴８３及び第１凹部２９は、第３面２７に配置される第１係合子５１の位置を規制する。第１穴８４及び第１凹部３０は、第３面２８に配置される第２係合子５４の位置を規制する。 The first plate portion 82 has a first recess 29 connected to the first hole 83, a first recess 30, a second recess 31, a pin hole 32, a third recess 33 and a fourth recess 34 connected to the first hole 84. It is formed on one surface 24. The first recesses 29 and 30, the second recess 31, the pin hole 32 and the fourth recess 34 penetrate the first plate portion 82 in the axis O direction. The first hole 83 and the first recess 29 regulate the position of the first engager 51 arranged on the third surface 27. The first hole 84 and the first recess 30 regulate the position of the second engager 54 arranged on the third surface 28.

第２板部８６は、軸線Ｏ方向から見て矩形状の穴部８７が複数形成されている。穴部８７は第２板部８６を軸線Ｏ方向に貫通する。穴部８７は全て同じ大きさであり、穴部８７の大きさは第１穴８３，８４の大きさよりも小さい。第１板部８２及び第２板部８６を貫通するピン穴３２にピン５６が嵌合し、第１板部８２と第２板部８６とが一体化されると、穴部８７は第１穴８３，８４に連なり、第１穴８３，８４の内側に第３面２７，２８がそれぞれ設けられる。 The second plate portion 86 is formed with a plurality of rectangular hole portions 87 when viewed from the axis O direction. The hole portion 87 penetrates the second plate portion 86 in the axis O direction. The holes 87 are all the same size, and the size of the holes 87 is smaller than the sizes of the first holes 83 and 84. When the pin 56 is fitted into the pin hole 32 penetrating the first plate portion 82 and the second plate portion 86 and the first plate portion 82 and the second plate portion 86 are integrated, the hole portion 87 becomes the first. It is connected to the holes 83 and 84, and the third surfaces 27 and 28 are provided inside the first holes 83 and 84, respectively.

第２板部８６は、第１板部８２に形成された第１凹部２９，３０及び第４凹部３４にそれぞれ連なる第１凹部２９，３０及び第４凹部３４が形成されている。穴部８７には圧縮ばね５０が収容される。第２板部８６の外周には突部２３が配置されている。第２板部８６にも第１凹部２９，３０が形成されるので、第１係合子５１及び第２係合子５４が揺動するときに腕５２が第２板部８６に干渉しないようにできる。第２板部８６にも第４凹部３４が形成されるので、リテーナ６５（図６参照）を付勢する圧縮ばね（図示せず）を第４凹部３４に収容し易くできる。 The second plate portion 86 is formed with first recesses 29, 30 and fourth recesses 34, which are connected to the first recesses 29, 30 and the fourth recess 34, respectively, formed in the first plate portion 82. A compression spring 50 is housed in the hole 87. A protrusion 23 is arranged on the outer periphery of the second plate portion 86. Since the first recesses 29 and 30 are also formed in the second plate portion 86, the arm 52 can be prevented from interfering with the second plate portion 86 when the first engaging element 51 and the second engaging element 54 swing. .. Since the fourth recess 34 is also formed in the second plate portion 86, the compression spring (not shown) for urging the retainer 65 (see FIG. 6) can be easily accommodated in the fourth recess 34.

第１板部８２の内周面８５及び第２板部８６の内周面８８に、スリーブ８９の第１部９０が圧入される。スリーブ８９は、筒状の第１部９０と、第１部９０よりも外径が大きいフランジ状の第２部９１と、を備えている。第１板部８２の第１面２４に第２部９１は突き当てられる。第１板部８２及び第２板部８６は、スリーブ８９の内周に形成されたスプライン９２が入力軸１１（図１０参照）に係合して、入力軸１１に結合する。第１部９０の外径は、第３部材６０の内周面６２の直径よりも小さい。留め具６４は、突部２３の内面に形成された溝（図示せず）に取り付けられ、第３部材６０を第１部材８１に対して軸線Ｏ方向に固定する。 The first portion 90 of the sleeve 89 is press-fitted into the inner peripheral surface 85 of the first plate portion 82 and the inner peripheral surface 88 of the second plate portion 86. The sleeve 89 includes a tubular first portion 90 and a flange-shaped second portion 91 having a larger outer diameter than the first portion 90. The second part 91 is abutted against the first surface 24 of the first plate part 82. In the first plate portion 82 and the second plate portion 86, the spline 92 formed on the inner circumference of the sleeve 89 engages with the input shaft 11 (see FIG. 10) and is coupled to the input shaft 11. The outer diameter of the first part 90 is smaller than the diameter of the inner peripheral surface 62 of the third member 60. The fastener 64 is attached to a groove (not shown) formed on the inner surface of the protrusion 23, and fixes the third member 60 to the first member 81 in the axis O direction.

クラッチ装置８０は、第１板部８２に第１穴８３，８４が形成され、第１穴８３，８４に連なる穴部８７が第２板部８６に形成されるので、第１穴８３，８４及び穴部８７の各々の形状を単純化できる。第１穴８３，８４に段差（第１実施形態における第３面２７，２８）を設けなくて良いので、第１部材８１を第１板部８２と第２板部８６とに分割することにより、第１部材８１の製造を容易にできる。 In the clutch device 80, the first holes 83, 84 are formed in the first plate portion 82, and the hole portion 87 connected to the first holes 83, 84 is formed in the second plate portion 86, so that the first holes 83, 84 are formed. And each shape of the hole 87 can be simplified. Since it is not necessary to provide a step (third surface 27, 28 in the first embodiment) in the first holes 83, 84, the first member 81 is divided into a first plate portion 82 and a second plate portion 86. , The first member 81 can be easily manufactured.

なお、第１係合子５１及び第２係合子５４が第２部材４０に係合するときには、主に第１板部８２（特に周方向の第１穴８３，８４の縁）に力が加わるので、第１板部８２はある程度の硬さが要求される。一方、第２板部８６は、第１板部８２に比べて、要求される硬さは低い。そこで、第１部材８１を第１板部８２と第２板部８６とに分割することにより、要求される硬さに応じて、第１板部８２と第２板部８６に加える熱処理の条件を変えたり材質を変えたりできる。 When the first engaging element 51 and the second engaging element 54 engage with the second member 40, a force is mainly applied to the first plate portion 82 (particularly, the edges of the first holes 83 and 84 in the circumferential direction). , The first plate portion 82 is required to have a certain degree of hardness. On the other hand, the hardness of the second plate portion 86 is lower than that of the first plate portion 82. Therefore, by dividing the first member 81 into the first plate portion 82 and the second plate portion 86, the heat treatment conditions applied to the first plate portion 82 and the second plate portion 86 according to the required hardness. Can be changed or the material can be changed.

次に図１１及び図１２を参照して第４実施の形態について説明する。第３実施形態では、第１部材８１に設けられた突部２３に留め具６４を取り付けて第３部材６０を固定する場合について説明した。これに対し第４実施形態では、第１部材１０１に取り付けられるスリーブ１０２の外周の溝１０４に留め具７４を取り付けて第３部材６０を固定する場合について説明する。なお、他の実施形態と同一の部分については、同一の符号を付して以下の説明を省略する。 Next, a fourth embodiment will be described with reference to FIGS. 11 and 12. In the third embodiment, a case where the fastener 64 is attached to the protrusion 23 provided on the first member 81 to fix the third member 60 has been described. On the other hand, in the fourth embodiment, a case where the fastener 74 is attached to the groove 104 on the outer periphery of the sleeve 102 attached to the first member 101 to fix the third member 60 will be described. The same parts as those of the other embodiments are designated by the same reference numerals, and the following description will be omitted.

図１１は第４実施の形態におけるクラッチ装置１００の一部の分解立体図であり、図１２は第１部材１０１、第３部材６０及び留め具７４の軸線Ｏを含む断面図である。クラッチ装置１００は、第１実施形態と同様に、第１部材１０１と軸線Ｏ方向に対向する第２部材４０を備えている。図１２では、軸線Ｏを境にした片側の図示および第２部材４０の図示が省略されている。 FIG. 11 is an exploded three-dimensional view of a part of the clutch device 100 according to the fourth embodiment, and FIG. 12 is a cross-sectional view including an axis O of the first member 101, the third member 60, and the fastener 74. Similar to the first embodiment, the clutch device 100 includes a second member 40 facing the first member 101 in the O direction of the axis. In FIG. 12, the illustration on one side with the axis O as a boundary and the illustration of the second member 40 are omitted.

第１板部８２及び第２板部８６を備える第１部材１０１は、第１板部８２及び第２板部８６の内周面８５，８８に圧入されるスリーブ１０２を介して、入力軸１１（図１２参照）に結合される。スリーブ１０２の第１部１０３の外径は、第３部材６０の内周面６２の直径よりも小さい。第１部１０３の外周面には、周方向に延びる溝１０４が形成されている。第２板部８６に第３部材６０を密着させた状態で、留め具７４を溝１０４に嵌め、留め具７４を第３部材６０に接触させることにより、第１部材１０１に対して第３部材６０が固定される。第３実施形態で説明した第１部材８１（図９参照）の突部２３を省略できるので、第１部材１０１を軽量化できる。 The first member 101 including the first plate portion 82 and the second plate portion 86 has an input shaft 11 via a sleeve 102 press-fitted into the inner peripheral surfaces 85 and 88 of the first plate portion 82 and the second plate portion 86. (See FIG. 12). The outer diameter of the first portion 103 of the sleeve 102 is smaller than the diameter of the inner peripheral surface 62 of the third member 60. A groove 104 extending in the circumferential direction is formed on the outer peripheral surface of the first portion 103. With the third member 60 in close contact with the second plate portion 86, the fastener 74 is fitted into the groove 104, and the fastener 74 is brought into contact with the third member 60 to bring the fastener 74 into contact with the third member 60, whereby the third member is compared with the first member 101. 60 is fixed. Since the protrusion 23 of the first member 81 (see FIG. 9) described in the third embodiment can be omitted, the weight of the first member 101 can be reduced.

以上、実施の形態に基づき本発明を説明したが、本発明は上記実施の形態に何ら限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変形が可能であることは容易に推察できるものである。例えば、第１係合子５１や第２係合子５４（係合子）の数や形状、係合子が係合する第２穴４３の数は例示であり、適宜設定できる。 Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and various improvements and modifications can be made without departing from the spirit of the present invention. It is easy to guess. For example, the number and shape of the first engaging element 51 and the second engaging element 54 (engaging element) and the number of the second holes 43 with which the engaging elements are engaged are examples and can be set as appropriate.

実施形態では、第１部材２０，７１，８１，１０１が入力軸１１に結合し、第２部材４０が出力軸１２に結合する場合について説明したが、必ずしもこれに限られるものではない。これとは逆に、第１部材２０，７１，８１，１０１が出力軸１２に結合し、第２部材４０が入力軸１１に結合することは当然可能である。 In the embodiment, the case where the first member 20, 71, 81, 101 is coupled to the input shaft 11 and the second member 40 is coupled to the output shaft 12 has been described, but the present invention is not limited to this. On the contrary, it is naturally possible that the first member 20, 71, 81, 101 is coupled to the output shaft 12 and the second member 40 is coupled to the input shaft 11.

実施形態では、第１部材２０，７１，８１，１０１や第２部材４０の中心にそれぞれ入力軸１１や出力軸１２が結合する場合、即ち第１部材や第２部材の軸線Ｏと入力軸や出力軸とが一致する場合について説明したが、必ずしもこれに限られるものではない。例えば、軸で支持された第１部材や第２部材の外周面に歯形を付け、この歯形と入力軸や出力軸に設けられたギヤとのかみ合いによって、軸を中心に回転する第１部材や第２部材にトルクを伝達することは当然可能である。 In the embodiment, when the input shaft 11 and the output shaft 12 are connected to the centers of the first member 20, 71, 81, 101 and the second member 40, that is, the axis O and the input shaft of the first member and the second member, respectively.
