A first end portion (21a) of a worm shaft (21) and a first bearing (22) that supports the first end portion (21a) are housed in a first end housing portion in a housing (20). The first end portion (21a) is urged toward a worm wheel (24) by an urging member (25). A rotation regulation portion housing recess (80) is formed in a portion that defines the first end housing portion on an inner surface (20a) of the housing (20). An elastic member (60) includes an arc-shaped buffer portion (61) that is interposed between the portion that defines the inner surface (20a) and an outer peripheral surface of the first bearing (22), and a rotation regulation portion (62) that extends from the buffer portion (61) and is housed in the rotation regulation portion housing recess (80). The rotation regulation portion (62) includes a hollow portion which suppresses load transmission from the rotation regulation portion (62) to the buffer portion (61) during rotation regulation.
