Abstract (en)

A cam 7, which is rotated by a motor 3, drives an actuating lever 8 through a torque receiving portions 8a or 8b to move the actuating lever 8 to the door-unlocking position or to the door-locking position and stops when it abuts a stopper walls 8d or 8e which are formed on the actuating lever 8. The intermediate reduction gear 5, which transmits rotating torque through a spring 6, rotates after the cam 7 stops and gradually stops while bending the spring 6. When the motor 3 is deenergized in this state, the intermediate reduction gear 5 is driven in the opposite direction due to elastic energy accumulated in the spring 6. Thus, the cam leaves the stopper walls 8d or 8e of the actuating lever 8 before it stops.
