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 includes a reaction force chamber provided concentrically with respect to the input shaft and the output shaft, and a reaction force mechanism fitted into the reaction force chamber so as to be slidable in the axial direction. a reaction force piston connected to one of the shaft and the output shaft; a reaction force receiver provided on the other of the input shaft and the output shaft to face the reaction piston in the axial direction; a reaction piston and the reaction force. Holes drilled in the axial direction at multiple locations on the circumference on one side of the receiving part, an elastically deformable plate covering these holes, and a plate at positions corresponding to the holes on the other side of the reaction piston and the reaction force receiving part. Steering force control of a power steering device comprising a protrusion formed in a substantially semicircular shape and abutting the plate, and a hydraulic pressure generating means for generating hydraulic pressure in the reaction force chamber according to vehicle speed, etc. Device.
