Description

この装置では、レリーズ時には、レリーズ機構によって、プレッシャ部材の押圧部がクラッチ部から離れる方向に移動させられる。これにより、クラッチ部はオフになる。このとき、レリーズ機構によるレリーズ力は、遠心子によって押圧力を受ける部分以外の部分に作用する。したがって、遠心子による押圧力とレリーズ力によって回転部材がドラグトルクを発生することはない。このため、例えば、ドラグトルクがトランスミッション側に伝達され、ドグクラッチが解除されにくい等の不具合を抑えることができる。 In this apparatus, at the time of release, the release mechanism, the pressing portion of the pressure member is moved in a direction away from the clutch unit. Thereby, the clutch unit is turned off. At this time, the release force by the release mechanism acts on a portion other than the portion receiving the pressing force by the centrifuge. Therefore, the rotary member does not generate drag torque due to the pressing force by the centrifuge and the release force. For this reason, for example, it is possible to suppress such a problem that the drag torque is transmitted to the transmission side and the dog clutch is difficult to be released.

（８）好ましくは、クラッチ部は、クラッチハウジングに係合する第１クラッチプレートと、クラッチハブに係合する第２クラッチプレートと、を有する。 (8) Preferably, the clutch portion has a first clutch plate engaged with the clutch housing and a second clutch plate engaged with the clutch hub.

本体部６１は、環状の部材であって、軸方向内側の側面の外周部に押圧面６１ａが形成されている。この押圧面６１ａが第１クラッチプレート５１に当接する。また、本体部６１の内周端には、複数の係合突起６１ｂが形成されている。この係合突起６１ｂがクラッチセンタ４の係合溝４２ａに係合している。したがって、第１プレッシャプレート６は、クラッチセンタ４に対して、軸方向に所定の範囲（係合溝４２ａが形成された範囲）で軸方向に移動自在であり、かつ回転不能である。本体部６１の軸方向外側の側面において、外周部には、支持突起６１ｃが形成されている。
The main body portion 61 is an annular member, and a pressing surface 61 a is formed on the outer peripheral portion of the axially inner side surface. The pressing surface 61 a abuts on the first clutch plate 51. Further, at the inner peripheral end of the main body portion 61, a plurality of engagement protrusions 61b are formed. The engagement protrusion 61 b is engaged with the engagement groove 42 a of the clutch center 4. Therefore, the first pressure plate 6 is axially movable in a predetermined range (a range in which the engagement groove 42 a is formed) in the axial direction with respect to the clutch center 4 and is non-rotatable. A support protrusion 61 c is formed on the outer peripheral portion of the side surface on the axially outer side of the main body portion 61.
