摘要： An electric power steering apparatus comprises a steering assisting electric motor having an output shaft and a speed reduction mechanism. The speed reduction mechanism includes conical first and second gears to be engaged with each other. The first and second gears include a plurality of teeth each having a tooth surface. The mutually corresponding tooth surfaces of the first and second gears each include engaging regions to be engaged with each other. A center position in a tooth width direction of the engaging region of each tooth surface of the first gear in an unloaded state is offset by a first offset amount from center position in the tooth width direction of the tooth surface of the first gear to a relatively small end portion of the tooth of the first gear. A cener position in a tooth width direction of the engaging region of each tooth surface of the second gear in an unloaded state is offset by a second offset amount from a center position in the tooth width direction of the tooth surface of the second gear to a relatively small end portion of the tooth of the second gear.

摘要： A steering device has a guide rail and a holding rubber. The guide rail is mounted on a mounting stay of a vehicle by way of an upper bracket, and the holding rubber restricts movement of the guide rail relative to the upper bracket. The guide rail has a fixed portion and a main body portion extending forward of the vehicle along the axial direction of a steering shaft from the fixed portion. The main body portion is inserted into a through hole of a vehicle body bracket. The holding rubber has a positioning protrusion and a detent pawl for restricting movement of the guide rail relative to the upper bracket before being fixed to the mounting stay so as to hold them at a mounting position. The detent pawl is formed so as to reduce a restricting force for restricting movement of the guide rail relative to the upper bracket as the guide rail comes closer to the mounting stay by screwing a nut onto a bolt.
