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