制御動力舵取装置。 An input shaft into which the steering torque from the steering wheel is input and an output shaft which transmits the steering angle of the input shaft to the wheels are connected so as to be relatively rotatable, and a hydraulic switching valve mechanism is provided between the two shafts. a spring member that operates the hydraulic switching valve mechanism by relative rotation between the two, controls the supply and discharge of hydraulic oil to each oil chamber of the power cylinder that assists steering force, and biases the output shaft toward the input shaft; In the power steering device in which hydraulic pressure is applied in the same direction, the biasing mechanism that biases the output shaft toward the input shaft includes a first piston that directly biases the output shaft, and a first piston that biases the output shaft directly; an oil chamber that urges the oil chamber with hydraulic pressure; a second piston provided on the opposite side of the oil chamber to the first piston; and a spring member that urges the second piston toward the oil chamber. When a hydraulic pressure above a certain level is applied to the oil chamber of the second piston and the second piston is displaced above a certain level due to displacement of the spring member, further displacement of the second piston is prevented. A stopper mechanism for regulating the hydraulic pressure is provided, a hydraulic pressure sensor for detecting the hydraulic pressure in the oil chamber is provided in a hydraulic circuit for introducing hydraulic pressure into the oil chamber, and a signal from the hydraulic pressure sensor is fed back to a hydraulic pressure control means for controlling the hydraulic pressure. A steering torque feedback control power steering device characterized by:
