制御装置。[Claims for Utility Model Registration] A differential limiting mechanism that limits differential movement of a differential device using hydraulic pressure is provided, and an input shaft that receives the rotational force of a steering wheel is connected to an output shaft on the steering wheel side. The power cylinder is equipped with a type of power cylinder in which the supply and discharge of hydraulic pressure to the power cylinder is controlled according to the amount of torsion of the torsion bar, and the amount of torsion of the torsion bar is controlled by the hydraulic pressure supplied to the hydraulic reaction force mechanism. In this vehicle, a pressure control valve that limits the hydraulic pressure supplied to the differential limiting mechanism is introduced, and a part of the hydraulic pressure after being controlled by this valve is introduced, and the hydraulic pressure with opposite characteristics to that hydraulic pressure is applied to the pressure control valve. A vehicle power steering operating force control device that includes a pressure conversion mechanism that supplies a hydraulic reaction force mechanism to a power cylinder.
