An electric power steering apparatus 1 comprises a worm gear 42, a worm wheel 43 that is connected to the worm gear, a bearing portion (45B, Fig 4) that rotatably supports the worm gear, a biasing portion, in the form of a coil spring (46E, Fig 4), that biases the bearing portion in a preload direction to push the worm gear against the worm wheel, a bearing case (46A, Fig 4) that supports the bearing portion, and guides the movement of the bearing portion along the preload direction and a shock absorbing member (46B, Fig 4) that is provided at a location. The bearing portion moves in an opposite direction of the preload direction to be brought into contact with the shock absorbing member at the location. |
