取装置。[Claims for Utility Model Registration] (1) A first supply pump that delivers pressure oil, a first pressure oil passage that supplies pressure oil from the first supply pump to a steering power cylinder, and the first supply pump. and the first pressure oil passage, a pressure oil flow rate adjustment device that adjusts the flow rate of pressure oil from the first supply pump to the first pressure oil passage to a constant value, a steering force input shaft and a steering force output shaft. A power steering device comprising: a steering force control section that is operated by relative rotation with the first pressure oil passage and increases or decreases the pressure oil pressure acting on the power cylinder from the first pressure oil passage in accordance with an increase or decrease in the relative rotation; The first pressure oil passage includes a hydraulic motor driven at a constant speed by a constant flow of pressure oil flowing in the first pressure oil passage, and a hydraulic motor that is operatively connected to the hydraulic motor and is operated by the hydraulic motor to generate hydraulic pressure. A power steering device comprising: a second supply pump for supplying pressure oil to a clutch device or a reaction force control device for increasing/decreasing steering wheel torque. (2) The second supply pump has its other end connected to one end of a second pressure oil passage connected to a hydraulic clutch device or a reaction force control device for increasing/decreasing handle torque, and
The pressure oil passage has a discharge pressure passage connected to the reservoir,
The power steering device according to claim 1, wherein the exhaust pressure passage includes a return flow rate control valve that controls the amount of pressure oil returned to the reservoir from the second pressure oil passage.
