摘要： An electric power steering apparatus for an automobile includes a steering shaft (102) connected to a steering wheel of the automobile; a pinion shaft (104) having an upper end connected to the steering shaft; a torque sensor (121) for sensing torque generated by rotation of the steering shaft; an electronic control unit (123) adapted to receive an electrical signal from the torque sensor; a motor (130), driving of the motor being controlled by the electronic control unit; a reduction mechanism (140) having a worm shaft (210) and a worm wheel (203), the worm shaft having a worm formed on an outer peripheral surface of the worm shaft, the worm shaft being contained in a housing (301), the worm wheel being formed on a side of the steering shaft, the reduction mechanism being driven by the motor; a support member (303) for enclosing an end-side outer peripheral surface of the worm shaft; and an elastic member (305) for applying elastic force to the support member in a direction slanted away from an axial direction of the worm shaft. The gap between the worm wheel and the worm shaft is compensated for and backlash is avoided. Since a single elastic member is used, the number of components is reduced, the manufacturing process is simplified, and the manufacturing cost is reduced.
