舵取装置。[Claims for Utility Model Registration] The opening of the throttle section interposed between the spool and the valve box in which the spool is fitted is adjusted in accordance with the relative displacement that occurs between the spool that moves in the axial direction as the steering wheel is operated. In the power steering device, the power steering device includes a direction switching valve that controls the direction of supply of hydraulic fluid to a hydraulic cylinder for steering assistance, and a reaction force device that restrains the relative displacement by a spring reaction force. A power steering device comprising a reaction force device that generates a reaction force that differs depending on the direction of movement of the spool.
