Device for driving a movable member in vehicle

摘要

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