手段とによつて構成して成る動力舵取装置の操舵
力制御装置。 A power steering device equipped with a servo valve that is operated based on the relative rotation of the input shaft and output shaft and controls the supply and discharge of pressure oil to the power cylinder, and a reaction force mechanism that changes the steering torque according to vehicle speed, etc. In the steering force control device, the reaction force mechanism controls a spring that applies a reaction force and pressure oil to a control pressure according to vehicle speed etc. using a linear solenoid valve, and introduces this control pressure to cause the spring to control the pressure. A steering force control device for a power steering device, comprising means for reducing reaction force.
