する４輪操舵装置。 A hydraulic actuator installed to operate in response to pressure oil supplied from a hydraulic pump and steer the rear wheels, and a power steering device for front wheels interposed in an oil passage connecting the hydraulic actuator and the hydraulic pump. The hydraulic pressure generated in the left and right pressure chambers is introduced as a pilot pressure, and the communication state between the oil passage on the hydraulic actuator side and the oil passage on the hydraulic pump side is controlled according to the steering direction of the front wheels and the pilot pressure. A four-wheel steering device equipped with a steering control valve according to the present invention, characterized in that a damper having a damping frequency of 3 to 10 Hz is provided between a steering member that is displaced during front wheel steering and a vehicle body side.
