Device for driving a movable member in vehicle.

摘要

A device for driving a movable member in vehicle comprises a driving motor (60) provided to be rotated in a predetermined direction, a reduction gear train for decelerating the rotating motion of the driving motor, and a crank mechanism for transmitting the rotation of the motor to an output shaft to be coupled with a driven member and a casing (35) for enclosing the motor, the reduction gear train and the crank mechanism. Adjacent two gears (68,70) in the reduction gear train are rotatably supported coaxially to the casing (35), and both gears are disposed relatively movably in the axial direction. The two gears are coupled through a clutch mechanism (90) to integrally rotate, disengaged by a manual operating member (100) as required, and only the gear (70) near the output shaft can be rotated.
