A holder has a holder engagement portion in at least a position sandwiching a pad from both sides in a third direction orthogonal to both a first direction that is an urging direction of an elastic member and a second direction that is an axial direction of a worm accommodation portion. The pad has a pad engagement portion that comes into contact with the holder engagement portion on at least one of both side portions in the third direction. Based on contact between the holder engagement portion and the pad engagement portion, displacement of the pad in the third direction with respect to the holder is regulated.
