PURPOSE:To enable engaging performance between a pinion and a ring gear to improve by arranging a contact pressure spring between a shaft, having a movable contact, and a plunger so as to contract said spring in case the pinion gets behind to plunge out. CONSTITUTION:A contact pressure spring 17 is arranged between a shaft 8 having a movable contact 10 and a plunger 7, by which even if a drive spring 27 is deformed and a pinion 23 gets behind to plunge out due to inertial weight of an overrunning clutch 22, the pinion 23 and the like, the contact pressure spring 17 contracts and movement of a movable contact 10 is delayed to improve engagement between the pinion 23 and a ring gear 24 while shock can be absorbed by the drive spring 27 in case the pinion 23 clashes on the ring gear 24. Still more, the number of parts can be prevented from increasing since the contact pressure spring 17 is used. |
