Abstract
A rotatable shaft of a motor main body and a worm shaft of a speed reducing unit are drivingly coupled to each other by a clutch. Surrounding walls, which are arranged radially outward of the clutch to substantially entirely surround the clutch in an imaginary plane that extends substantially perpendicular to the axis of the worm shaft, are formed integrally with a gear housing. Thus, the surrounding walls restrain outward movement of grease, which is applied to predetermined portions of the clutch, so that effluence of the grease from the clutch is restrained.
