摘要： A power steering apparatus that is arranged in that hydraulic force to be supplied to a hydraulic cylinder is in a condition in which the hydraulic force is not raised even though an electric motor performs stand-by operations when a steering angle or an input torque is smaller than a predetermined value, and in that smooth steering is enabled without causing abrupt changes in hydraulic force when the steering angle or the input torgue exceedes the predetermined value and the electric motor is started driving at proper revolutions according to operations of a steering wheel.
