A holder member (36) includes a holder-side holding surface (40) for internally fitting and holding a rolling bearing (18c) on a tip end side and a holder-side held surface (42) eccentric to a center axis of the holder-side holding surface (40). A guide member (37) is internally fitted and held into a guide holding portion (25) of a housing (12a) and includes a guide-side holding surface (48) for internally fitting and holding the holder member (36) to be capable of swinging about a center axis of the holder-side held surface (42). A first elastic urging member elastically urges a tip end portion of a worm (14) toward a worm wheel side by elastically urging the holder member (36) in a direction to rotate with respect to the guide member (37). Therefore, a structure which can more effectively suppress generation of gear rattle noise at a meshing portion between a wheel tooth and a worm tooth can be realized.
