Abstract
An electric power steering system includes a worm reduction gear. An end portion of worm shaft, the end portion being distant from a motor, is urged toward a worm wheel. The worm shaft is supported by a bearing at an end portion close to the motor. A movement inhibitor that includes an elastic element is arranged between the worm shaft and the bearing. The movement inhibitor allows the worm shaft to move within a predetermined range in a radial direction of the worm shaft with respect to the bearing and allows the worm shaft to move within a predetermined range in an axial direction of the worm shaft with respect to the bearing.
