Abstract
An electric power steering device includes a housing, a rotating shaft for steering, a worm wheel, a worm shaft, a tip side bearing, an electric motor, and biasing mechanism. The biasing mechanism includes a wedge piece and an elastic member for a wedge piece. The wedge piece is disposed between an outer circumferential surface of the tip side bearing and an inner circumferential surface of the housing in a state where the wedge piece in a circumferential direction is displaceable. The elastic member for a wedge piece applies elastic force toward one circumferential side to the wedge piece.
