A worm reducer includes a worm shaft; a worm wheel; a housing that houses the worm shaft and the worm wheel; a bearing that holds the worm shaft inside the housing; a coil spring that contacts an outer peripheral surface of the bearing and applies an urging force toward the worm wheel; and a preload member that is screwed into and fixed to the housing and pressurizes the coil spring. A winding direction of the coil spring is different from a winding direction of a thread of the preload member, and contact resistance between the coil spring and the preload member is greater than contact resistance between the coil spring and the bearing.
