A worm reducer includes a worm shaft (164); a worm wheel (163); a housing (153) that houses the worm shaft (164) and the worm wheel (163); a bearing that holds the worm shaft (164) inside the housing (153); a coil spring (170) that contacts an outer peripheral surface of the bearing and applies an urging force toward the worm wheel (163); and a preload member (155) that is screwed into and fixed to the housing (153) and pressurizes the coil spring (170). A winding direction of the coil spring (170) is different from a winding direction of a thread of the preload member (155), and contact resistance between the coil spring (170) and the preload member (155) is greater than contact resistance between the coil spring (170) and the bearing.
