The ring member 45 is provided with an abutment portion 49 that abuts against the axially facing surface of the intermittent member 7 in the engagement window portion 19 of the outer case 3, and the movable member 23 operated by the electromagnet 25. The axial movement operating force is transmitted to the intermittent member 7.

電磁石２５は、可動部材２３の外径側でアウタケース３の側壁１５に対して軸方向に隣接配置され、電磁コイル５１と、コア２７とを備えている。電磁コイル５１は、樹脂でモールド成形され、外部に引き出されてコントローラ（不図示）に接続されたリード線（不図示）が接続されており、コントローラによって通電が制御されている。この電磁コイル５１は、コア２７に収容されている。   The electromagnet 25 is disposed adjacent to the side wall 15 of the outer case 3 in the axial direction on the outer diameter side of the movable member 23, and includes an electromagnetic coil 51 and a core 27. The electromagnetic coil 51 is molded with resin, and is connected to a lead wire (not shown) that is pulled out and connected to a controller (not shown), and energization is controlled by the controller. The electromagnetic coil 51 is accommodated in the core 27.

コア２７は、磁性材料から形成され、軸方向端面に固定部材４７が当接されて電磁石２５の軸方向位置が位置決めされると共に、回り止め部材５３によってキャリアなどの静止系部材に対して電磁石２５が回転方向に回り止めされている。このコア２７の外径側には、軸方向のアウタケース３側に延設された延設部５５が設けられている。延設部５５は、内周面が磁束が透過可能に設定された摺動接触面をもってアウタケース３の側壁１５の外周側を覆い支持可能に設けられている。このため、アウタケース３の側壁１５に周方向の縁部が開口された係合窓部１９を複数設けたとしても、係合窓部１９以外の側壁１５とコア２７との間で磁束の受け渡しを行うことができ、磁束の透過によって形成される磁束ループの磁路効率を低下させることがない。   The core 27 is made of a magnetic material, and the axial position of the electromagnet 25 is positioned by abutting the fixing member 47 on the end surface in the axial direction, and the electromagnet 25 with respect to a stationary system member such as a carrier by the anti-rotation member 53. Is prevented from rotating in the direction of rotation. On the outer diameter side of the core 27, an extending portion 55 that extends toward the outer case 3 side in the axial direction is provided. The extending portion 55 is provided so as to cover and support the outer peripheral side of the side wall 15 of the outer case 3 with a sliding contact surface whose inner peripheral surface is set so that magnetic flux can be transmitted. For this reason, even if a plurality of engagement window portions 19 having circumferential edges opened are provided on the side wall 15 of the outer case 3, the magnetic flux is transferred between the side wall 15 other than the engagement window portion 19 and the core 27. The magnetic path efficiency of the magnetic flux loop formed by the transmission of the magnetic flux is not lowered.

このようなクラッチ装置１のアウタケース３の複数の係合窓部１９内には、断続部材７を断続部９の接続解除方向に付勢する付勢部材２１がそれぞれ配置されている。   In each of the plurality of engagement window portions 19 of the outer case 3 of the clutch device 1, biasing members 21 that bias the intermittent member 7 in the direction in which the intermittent portion 9 is disconnected are disposed.

複数の付勢部材２１は、伸縮可能なコイルバネからなり、アウタケース３の係合窓部１９が位置する部分に対向して設けられた孔部５７にそれぞれ配置されている。この付勢部材２１の一端側は孔部５７の底部に当接され、他端側は断続部材７の係合凸部１７に固定された受け部材２９に当接されている。   The plurality of urging members 21 are made of coil springs that can be expanded and contracted, and are respectively disposed in holes 57 that are provided to face a portion where the engagement window 19 of the outer case 3 is located. One end side of the biasing member 21 is in contact with the bottom of the hole portion 57, and the other end side is in contact with a receiving member 29 fixed to the engagement convex portion 17 of the intermittent member 7.

受け部材２９は、薄板状のプレートを曲げ加工した部材からなり、一端側が断続部材７の係合凸部１７の当接部４９の端面に固定手段としてのボルト５９によって固定されている。また、受け部材２９の他端側は、一端側からアウタケース３側に曲げ加工され、付勢部材２１に当接されている。この受け部材２９は、断続部材７の軸方向移動と共に軸方向移動される。このため、断続部材７は、付勢部材２１の付勢力によって断続部９の接続解除方向に常時付勢されている。   The receiving member 29 is made of a member obtained by bending a thin plate-like plate, and one end side thereof is fixed to the end surface of the abutting portion 49 of the engaging convex portion 17 of the intermittent member 7 by a bolt 59 as a fixing means. Further, the other end side of the receiving member 29 is bent from the one end side to the outer case 3 side and is in contact with the urging member 21. The receiving member 29 is moved in the axial direction together with the axial movement of the intermittent member 7. For this reason, the intermittent member 7 is always urged in the direction of releasing the connection of the intermittent portion 9 by the urging force of the urging member 21.

このように構成されたクラッチ装置１では、電磁石２５の励磁によりコア２７とプランジャ４３とアウタケース３の側壁１５を透過する磁束で形成される最短の磁束ループを有効に用いることによって、プランジャ４３が断続部材７側に移動操作され、リング部材４５が付勢部材２１の付勢力に抗して当接部４９を介して断続部材７を押圧する。この可動部材２３による断続部材７の押圧操作により、断続部材７が断続部９の接続方向に移動され、断続部９が接続される。この断続部９の接続により、インナケース５と断続部材７とが一体回転可能に接続され、インナケース５とアウタケース３との間の動力伝達が可能となる。   In the clutch device 1 configured as described above, the plunger 43 is effectively used by effectively using the shortest magnetic flux loop formed by the magnetic flux that passes through the core 27, the plunger 43, and the side wall 15 of the outer case 3 by the excitation of the electromagnet 25. The ring member 45 is operated to move to the intermittent member 7 side and presses the intermittent member 7 through the contact portion 49 against the urging force of the urging member 21. By the pressing operation of the intermittent member 7 by the movable member 23, the intermittent member 7 is moved in the connecting direction of the intermittent portion 9, and the intermittent portion 9 is connected. Due to the connection of the intermittence portion 9, the inner case 5 and the intermittence member 7 are connected so as to be integrally rotatable, and power transmission between the inner case 5 and the outer case 3 becomes possible.

また、断続部９の接続解除では、電磁石２５への通電を停止することにより断続部材７が受け部材２９を介して付勢部材２１の付勢力によって電磁石２５側に移動操作される。この断続部材７の移動により、断続部材７が断続部９の接続解除方向に移動され、断続部９の接続が解除される。この断続部９の接続解除により、インナケース５と断続部材７とが相対回転可能となり、インナケース５とアウタケース３との間の動力伝達が遮断される。   Further, in the disconnection of the intermittent portion 9, the intermittent member 7 is moved to the electromagnet 25 side by the urging force of the urging member 21 through the receiving member 29 by stopping energization to the electromagnet 25. By the movement of the intermittent member 7, the intermittent member 7 is moved in the connection release direction of the intermittent portion 9, and the connection of the intermittent portion 9 is released. By releasing the connection of the intermittent portion 9, the inner case 5 and the intermittent member 7 can be rotated relative to each other, and power transmission between the inner case 5 and the outer case 3 is interrupted.

このようなクラッチ装置１では、アウタケース３の収容部１３の側壁１５に設けられた複数の係合窓部１９に、断続部材７を断続部９の接続解除方向に付勢する付勢部材２１がそれぞれ配置されているので、アウタケース３の周辺や内部に付勢部材２１を配置させるための占有スペースを新規に設ける必要がなく、装置の大型化を抑制することができる。   In such a clutch device 1, the urging member 21 that urges the intermittent member 7 in the disconnecting direction of the intermittent portion 9 is applied to the plurality of engagement window portions 19 provided on the side wall 15 of the accommodating portion 13 of the outer case 3. Therefore, it is not necessary to newly provide an occupied space for arranging the urging member 21 around or inside the outer case 3, and the size of the apparatus can be suppressed.

従って、アウタケース３の周辺や内部などの設計変更を伴うことなく、付勢部材２１を配置させることができるので、装置の大型化を抑制し、付勢部材２１を設けることができる。   Therefore, the urging member 21 can be arranged without changing the design of the periphery and the inside of the outer case 3, so that the apparatus can be prevented from being enlarged and the urging member 21 can be provided.

また、収容部１３の側壁１５の外周は、摺動接触して電磁石２５のコア２７に覆われているので、係合窓部１９以外の側壁１５とコア２７との間で磁束の受け渡しを行うことができ、磁路効率を低下させることがない。   Further, since the outer periphery of the side wall 15 of the housing portion 13 is in sliding contact and covered with the core 27 of the electromagnet 25, the magnetic flux is transferred between the side wall 15 other than the engagement window portion 19 and the core 27. And the magnetic path efficiency is not lowered.

さらに、複数の係合凸部１７には、係合窓部１９に配置される受け部材２９がそれぞれ設けられ、アウタケース３と受け部材２９との軸方向間には、付勢部材２１が配置されているので、アウタケース３の係合窓部１９内で、アウタケース３と断続部材７との係合と、付勢部材２１の付勢力を受ける受け部材２９の配置とを行うことができ、装置の大型化を抑制したまま、各機能を装置にもたせることができる。   Further, the plurality of engaging protrusions 17 are each provided with a receiving member 29 arranged in the engaging window portion 19, and an urging member 21 is arranged between the outer case 3 and the receiving member 29 in the axial direction. Therefore, the engagement between the outer case 3 and the intermittent member 7 and the arrangement of the receiving member 29 that receives the urging force of the urging member 21 can be performed within the engagement window portion 19 of the outer case 3. Each function can be given to the apparatus while suppressing the enlargement of the apparatus.

The plunger 139 is made of a magnetic material, and is disposed on the inner diameter side of the electromagnet 125 with an air gap (fine gap) set so as to allow magnetic flux to pass therethrough. A ring member 141 is integrally fixed to the inner periphery of the plunger 139.

リング部材１４１は、非磁性材料から形成され、プランジャ１３９の内周側からデフケース１０３側へ磁束が漏れることを防止している。また、リング部材１４１は、デフケース１０３のボス部４１３の外周に軸方向移動可能に配置され、デフケース１０３のボス部４１３の外周にスナップリングなどの固定部材１４３によって固定された規制部材１４５によって軸方向の移動規制がなされている。このリング部材１４１には、デフケース１０３の係合窓部１１９内で、断続部材１０７との軸方向の対向面に互いに当接する当接部１４７が設けられ、電磁石１２５によって作動される可動部材１２３による軸方向の移動操作力が断続部材１０７に伝達される。   The ring member 141 is formed of a nonmagnetic material, and prevents magnetic flux from leaking from the inner peripheral side of the plunger 139 to the differential case 103 side. The ring member 141 is disposed on the outer periphery of the boss portion 413 of the differential case 103 so as to be axially movable, and is axially moved by a regulating member 145 fixed to the outer periphery of the boss portion 413 of the differential case 103 by a fixing member 143 such as a snap ring. The movement restrictions are made. The ring member 141 is provided with an abutting portion 147 that abuts against the axially facing surface of the intermittent member 107 within the engaging window portion 119 of the differential case 103, and is provided by the movable member 123 that is operated by the electromagnet 125. The axial movement operation force is transmitted to the intermittent member 107.

電磁石１２５は、可動部材１２３の外径側でデフケース１０３の側壁１１５に対して軸方向に隣接配置され、電磁コイル１４９と、コア１２７とを備えている。電磁コイル１４９は、樹脂でモールド成形され、外部に引き出されてコントローラ（不図示）に接続されたリード線（不図示）が接続されており、コントローラによって通電が制御されている。この電磁コイル１４９は、コア１２７に収容されている。   The electromagnet 125 is disposed adjacent to the side wall 115 of the differential case 103 on the outer diameter side of the movable member 123 in the axial direction, and includes an electromagnetic coil 149 and a core 127. The electromagnetic coil 149 is molded with resin, is connected to a lead wire (not shown) that is pulled out and connected to a controller (not shown), and energization is controlled by the controller. The electromagnetic coil 149 is accommodated in the core 127.

コア１２７は、磁性材料から形成され、軸方向端面に規制部材１４５が当接されて電磁石１２５の軸方向位置が位置決めされると共に、回り止め部材（不図示）によってキャリアなどの静止系部材に対して電磁石１２５が回転方向に回り止めされている。このコア１２７の外径側には、軸方向のデフケース１０３側に延設された延設部１５１が設けられている。延設部１５１は、内周面が磁束が透過可能に設定された摺動接触面をもってデフケース１０３の側壁１１５の外周側を覆い支持可能に設けられている。このため、デフケース１０３の側壁１１５に周方向の縁部が開口された係合窓部１１９を複数設けたとしても、係合窓部１１９以外の側壁１１５とコア１２７との間で磁束の受け渡しを行うことができ、磁束の透過によって形成される磁束ループの磁路効率を低下させることがない。   The core 127 is made of a magnetic material, and the restricting member 145 is brought into contact with an axial end face to position the electromagnet 125 in the axial direction. The core 127 is fixed to a stationary member such as a carrier by a non-rotating member (not shown). Thus, the electromagnet 125 is prevented from rotating in the rotation direction. On the outer diameter side of the core 127, an extending portion 151 that extends toward the differential case 103 in the axial direction is provided. The extending portion 151 is provided so as to cover and support the outer peripheral side of the side wall 115 of the differential case 103 with a sliding contact surface whose inner peripheral surface is set so that magnetic flux can be transmitted. For this reason, even if a plurality of engagement window portions 119 whose peripheral edges are opened are provided on the side wall 115 of the differential case 103, the magnetic flux is transferred between the side wall 115 other than the engagement window portion 119 and the core 127. This can be done without reducing the magnetic path efficiency of the magnetic flux loop formed by the transmission of the magnetic flux.

このようなクラッチ装置１０１のデフケース１０３の複数の係合窓部１１９内には、断続部材１０７を断続部１０９の接続解除方向に付勢する付勢部材１２１がそれぞれ配置されている。   In each of the plurality of engagement window portions 119 of the differential case 103 of the clutch device 101, the urging members 121 for urging the intermittent member 107 in the disconnecting direction of the intermittent portion 109 are arranged.

複数の付勢部材１２１は、伸縮可能なコイルバネからなり、デフケース１０３の係合窓部１１９が位置する部分に対向して設けられた孔部１５３にそれぞれ配置されている。この付勢部材１２１の一端側は孔部１５３の底部に当接され、他端側は断続部材１０７の係合凸部１１７に固定された受け部材１２９に当接されている。   The plurality of urging members 121 are made of coil springs that can be expanded and contracted, and are respectively disposed in hole portions 153 provided to face the portion where the engagement window portion 119 of the differential case 103 is located. One end of the urging member 121 is in contact with the bottom of the hole 153, and the other end is in contact with a receiving member 129 fixed to the engagement convex portion 117 of the intermittent member 107.

受け部材１２９は、薄板状のプレートを曲げ加工した部材からなり、一端側が断続部材１０７の係合凸部１１７の当接部１４７の端面に固定手段としてのボルト１５５によって固定されている。また、受け部材１２９の他端側は、一端側からデフケース１０３側に曲げ加工され、付勢部材１２１に当接されている。この受け部材１２９は、断続部材１０７の軸方向移動と共に軸方向移動される。このため、断続部材１０７は、付勢部材１２１の付勢力によって断続部１０９の接続解除方向に常時付勢されている。   The receiving member 129 is made of a member obtained by bending a thin plate-like plate, and one end side thereof is fixed to the end surface of the abutting portion 147 of the engaging convex portion 117 of the intermittent member 107 by a bolt 155 as a fixing means. Further, the other end side of the receiving member 129 is bent from the one end side to the differential case 103 side and is in contact with the urging member 121. The receiving member 129 is moved in the axial direction together with the axial movement of the intermittent member 107. For this reason, the intermittent member 107 is constantly urged in the connection release direction of the intermittent portion 109 by the urging force of the urging member 121.

このように構成されたクラッチ装置１０１では、電磁石１２５の励磁によりコア１２７とプランジャ１３９とデフケース１０３の側壁１１５を透過する磁束で形成される最短の磁束ループを有効に用いることによって、プランジャ１３９が断続部材１０７側に移動操作され、リング部材１４１が付勢部材１２１の付勢力に抗して当接部１４７を介して断続部材１０７を押圧する。この可動部材１２３による断続部材１０７の押圧操作により、断続部材１０７が断続部１０９の接続方向に移動され、断続部１０９が接続される。この断続部１０９の接続により、サイドギヤ１０５と断続部材１０７とが一体回転可能に接続され、サイドギヤ１０５とデフケース１０３とが接続されて差動機構４０９がロック状態となる。   In the clutch device 101 configured as described above, the plunger 139 is intermittently formed by effectively using the shortest magnetic flux loop formed by the magnetic flux that passes through the side wall 115 of the core 127, the plunger 139, and the differential case 103 by the excitation of the electromagnet 125. The ring member 141 is operated to move toward the member 107, and the intermittent member 107 is pressed via the contact portion 147 against the urging force of the urging member 121. By the pressing operation of the intermittent member 107 by the movable member 123, the intermittent member 107 is moved in the connection direction of the intermittent portion 109, and the intermittent portion 109 is connected. By the connection of the intermittent portion 109, the side gear 105 and the intermittent member 107 are connected so as to be integrally rotatable, the side gear 105 and the differential case 103 are connected, and the differential mechanism 409 is locked.

また、断続部１０９の接続解除では、電磁石１２５への通電を停止することにより断続部材１０７が受け部材１２９を介して付勢部材１２１の付勢力によって電磁石１２５側に移動操作される。この断続部材１０７の移動により、断続部材１０７が断続部１０９の接続解除方向に移動され、断続部１０９の接続が解除される。この断続部１０９の接続解除により、サイドギヤ１０５と断続部材１０７とが相対回転可能となり、サイドギヤ１０５とデフケース１０３とが相対回転可能となって差動機構４０９のロック状態が解除される。   Further, in the disconnection of the intermittent portion 109, the intermittent member 107 is moved to the electromagnet 125 side by the urging force of the urging member 121 through the receiving member 129 by stopping energization to the electromagnet 125. Due to the movement of the intermittent member 107, the intermittent member 107 is moved in the connection release direction of the intermittent portion 109 and the connection of the intermittent portion 109 is released. By releasing the connection of the intermittent portion 109, the side gear 105 and the intermittent member 107 can be rotated relative to each other, the side gear 105 and the differential case 103 can be relatively rotated, and the differential mechanism 409 is unlocked.

このようなクラッチ装置１０１では、デフケース１０３の収容部１１３の側壁１１５に設けられた複数の係合窓部１１９に、断続部材１０７を断続部１０９の接続解除方向に付勢する付勢部材１２１がそれぞれ配置されているので、デフケース１０３の周辺や内部に付勢部材１２１を配置させるための占有スペースを新規に設ける必要がなく、装置の大型化を抑制することができる。   In such a clutch device 101, the biasing member 121 that biases the intermittent member 107 in the disconnecting direction of the intermittent portion 109 is provided on the plurality of engagement window portions 119 provided on the side wall 115 of the accommodating portion 113 of the differential case 103. Since they are respectively arranged, it is not necessary to newly provide an occupying space for arranging the biasing member 121 around or inside the differential case 103, and an increase in the size of the apparatus can be suppressed.

従って、デフケース１０３の周辺や内部などの設計変更を伴うことなく、付勢部材１２１を配置させることができるので、装置の大型化を抑制し、付勢部材１２１を設けることができる。   Therefore, the urging member 121 can be disposed without changing the design of the periphery or the inside of the differential case 103, and thus the apparatus can be prevented from being enlarged and the urging member 121 can be provided.

また、収容部１１３の側壁１１５の外周は、摺動接触して電磁石１２５のコア１２７に覆われているので、係合窓部１１９以外の側壁１１５とコア１２７との間で磁束の受け渡しを行うことができ、磁路効率を低下させることがない。   Moreover, since the outer periphery of the side wall 115 of the accommodating part 113 is slidably contacted and covered with the core 127 of the electromagnet 125, the magnetic flux is transferred between the side wall 115 other than the engagement window part 119 and the core 127. And the magnetic path efficiency is not lowered.

さらに、複数の係合凸部１１７には、係合窓部１１９に配置される受け部材１２９がそれぞれ設けられ、デフケース１０３と受け部材１２９との軸方向間には、付勢部材１２１が配置されているので、デフケース１０３の係合窓部１１９内で、デフケース１０３と断続部材１０７との係合と、付勢部材１２１の付勢力を受ける受け部材１２９の配置とを行うことができ、装置の大型化を抑制したまま、各機能を装置にもたせることができる。   Further, the plurality of engaging convex portions 117 are each provided with a receiving member 129 disposed in the engaging window portion 119, and an urging member 121 is disposed between the differential case 103 and the receiving member 129 in the axial direction. Therefore, the engagement between the differential case 103 and the intermittent member 107 and the arrangement of the receiving member 129 that receives the urging force of the urging member 121 can be performed within the engagement window portion 119 of the differential case 103. Each function can be given to the apparatus while suppressing the increase in size.

本実施の形態に係るクラッチ装置２０１は、受け部材２０３と付勢部材としてのバネ部２０５，２０７とは、連続する一部材で形成されている。なお、第１実施形態と同一の構成には、同一の記号を記して説明を省略するが、第１実施形態と同一の構成であるので、構成及び機能説明は第１実施形態を参照するものとし省略するが、得られる効果は同一である。   In the clutch device 201 according to the present embodiment, the receiving member 203 and the spring portions 205 and 207 as the urging members are formed as one continuous member. In addition, although the same code | symbol is described to the structure same as 1st Embodiment, description is abbreviate | omitted, but since it is the same structure as 1st Embodiment, a structure and functional description refer to 1st Embodiment. Although omitted, the obtained effects are the same.

図４〜図６に示すように、受け部材２０３は、アウタケース３の複数の係合窓部１９内に配置され、薄板状のプレートを曲げ加工した部材からなる。この受け部材２０３の一端側は、断続部材７の係合凸部１７の当接部４９の端面に固定手段としてのボルト２０９によって固定され、断続部材７の軸方向移動と共に受け部材２０３が軸方向移動される。また、受け部材２０３の他端側は、一端側からアウタケース３側に曲げ加工され、中央部の切欠部２１１を介してさらにアウタケース３側に弾性変形可能に曲げ加工されてアウタケース３の係合窓部１９内の側面に当接された一対のバネ部２０５，２０７が設けられている。このように構成されることにより、受け部材２０３と一対のバネ部２０５，２０７とは、連続する一部材で形成されている。   As shown in FIGS. 4 to 6, the receiving member 203 is disposed in the plurality of engagement window portions 19 of the outer case 3 and is made of a member obtained by bending a thin plate. One end side of the receiving member 203 is fixed to the end face of the contact portion 49 of the engaging convex portion 17 of the intermittent member 7 by a bolt 209 as a fixing means, and the axial direction of the intermittent member 7 causes the receiving member 203 to move in the axial direction. Moved. Further, the other end side of the receiving member 203 is bent from the one end side to the outer case 3 side, and further bent to the outer case 3 side through the notch portion 211 at the center so as to be elastically deformable. A pair of spring portions 205 and 207 are provided in contact with the side surfaces in the engagement window portion 19. With this configuration, the receiving member 203 and the pair of spring portions 205 and 207 are formed as one continuous member.

一対のバネ部２０５，２０７は、アウタケース３の側面に対して所定の付勢力を有して当接されている。この当接により、断続部材７は、一対のバネ部２０５，２０７の付勢力によって断続部９の接続解除方向に常時付勢されている。また、断続部材７がアクチュエータ１１によって移動操作されると、断続部材７が断続部９の接続方向に一対のバネ部２０５，２０７の付勢力に抗して移動される。このとき、一対のバネ部２０５，２０７は、基部側がアウタケース３の側面に対して、図６中の矢印で示すストローク分だけ移動するように弾性変形し、断続部９の接続状態では図６中の２点鎖線で示す状態で保持される。また、一対のバネ部２０５，２０７の外周側は、受け部材２０３の強度を保持する強度維持部２１３となっており、一対のバネ部２０５，２０７を受け部材２０３に形成させても、受け部材２０３の強度が低下することがない。   The pair of spring portions 205 and 207 are in contact with the side surface of the outer case 3 with a predetermined urging force. Due to this contact, the intermittent member 7 is constantly urged in the direction of disconnection of the intermittent portion 9 by the urging force of the pair of spring portions 205 and 207. When the intermittent member 7 is moved by the actuator 11, the intermittent member 7 is moved in the connection direction of the intermittent portion 9 against the urging force of the pair of spring portions 205 and 207. At this time, the pair of spring portions 205 and 207 are elastically deformed so that the base side moves by the stroke indicated by the arrow in FIG. 6 with respect to the side surface of the outer case 3, and FIG. It is held in the state shown by the middle two-dot chain line. Further, the outer peripheral side of the pair of spring portions 205 and 207 is a strength maintaining portion 213 that maintains the strength of the receiving member 203, and even if the pair of spring portions 205 and 207 is formed on the receiving member 203, the receiving member The strength of 203 does not decrease.

このようなクラッチ装置２０１では、受け部材２０３とバネ部２０５，２０７とが連続する一部材で形成されているので、付勢部材を別部材として設ける必要がなく、部品点数を削減することができる。また、付勢部材を別部材として設けたときのように、付勢部材を配置させるための孔部５７（図１参照）をアウタケース３に設ける必要がなく、断続部材に付勢力を付与する構造やアウタケース３の製造に関して簡易化することができる。このため、部品点数の削減や構造・製造の簡易化をすることができるので、コストを低減することができる。   In such a clutch device 201, since the receiving member 203 and the spring portions 205 and 207 are formed as one continuous member, it is not necessary to provide a biasing member as a separate member, and the number of parts can be reduced. . Further, unlike the case where the urging member is provided as a separate member, it is not necessary to provide the outer case 3 with the hole 57 (see FIG. 1) for arranging the urging member, and the urging force is applied to the intermittent member. The structure and manufacture of the outer case 3 can be simplified. For this reason, since the number of parts can be reduced and the structure and manufacturing can be simplified, the cost can be reduced.

なお、本発明の実施の形態に係るクラッチ装置では、断続部として噛み合いクラッチを用いているが、これに限らず、摩擦クラッチなど相対回転する一対の回転部材間の動力伝達を断続させることができる構成であれば、どのような形態であってもよい。   In the clutch device according to the embodiment of the present invention, the meshing clutch is used as the intermittent portion. However, the present invention is not limited to this, and power transmission between a pair of rotating members such as a friction clutch can be intermittently performed. Any configuration may be used as long as it is configured.

また、断続部材を移動操作するアクチュエータは、電磁石を起動源とする構成に限られるものではなく、他の例として、油圧シリンダ−ピストンを用いたもの、流体ダイヤフラムを用いたもの、電動モータソレノイド、流体ピストンなどにより可動な操作ロッドを用いたもの、小型電動モータとギヤ機構（付加してカム機構）を用いたものなど種々の起動源を採りうる。   In addition, the actuator for moving the intermittent member is not limited to the configuration using an electromagnet as an activation source, and other examples include those using a hydraulic cylinder-piston, those using a fluid diaphragm, electric motor solenoids, Various starting sources such as those using an operation rod movable by a fluid piston or the like, and those using a small electric motor and a gear mechanism (additionally a cam mechanism) can be adopted.
