取り装置。[Claims for Utility Model Registration] A system that switches according to input rotation from the handle. In a power steering device that is provided with a control valve and selectively supplies pressure oil to a hydraulic actuator linked to a linkage of a wheel via the control valve, a means for detecting the live load of a vehicle and a means for switching the arm control valve are provided. It is equipped with a reaction force chamber that expands and contracts accordingly, and a hydraulic switching valve that guides high pressure from the operating port to the upper bow reaction chamber to counter the switching pain of the control valve when the load is small. Features a power steering device.
