する動力舵取装置の操舵力制御装置。 A servo valve operates based on the relative rotation of the input shaft and output shaft to control the supply and discharge of pressure oil to the power cylinder, a reaction force mechanism that changes handle torque according to vehicle speed, etc., and a pressure oil discharged from the supply pump. a valve device that controls the flow rate of a constant flow of pressure oil and divides it into the servo valve side passage and the reaction force mechanism side passage, and controls the pressure oil diverted to the reaction mechanism to control the reaction oil pressure. In the steering force control device of the power steering device, a fixed throttle is inserted in a communication passage that communicates the servo valve side passage and the reaction force mechanism side passage, and each of the fixed throttles is provided with a throttle hole having a different diameter. A steering force of a power steering device characterized in that the plurality of throttle bodies are arranged on the upstream side and the throttle body with a large throttle hole is positioned on the downstream side, and are inserted in sequence. Control device.
