In a worm reducer, an urging member includes an urging shaft portion and an elastic pressing portion. The urging shaft portion is rotatably disposed inside a housing in a state in which a rotation center axis thereof is directed substantially parallel to a center axis of the worm wheel. The elastic pressing portion formed of an elastic material is externally fitted and fixed to a part of the urging shaft portion in an axial direction in an eccentric state with respect to the rotation center axis of the urging shaft portion. By rotating the urging shaft portion, an outer peripheral surface of the elastic pressing portion is pressed against an outer peripheral surface of a second bearing externally fitted to a worm shaft.
