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.
