PURPOSE: Structure for a hydraulic pressure control valve of a vehicle is provided to improve steering stability and ride comfort, to decrease hysteresis by making a handle firm in high speed driving by generating detent force. CONSTITUTION: A hydraulic pressure control valve for operating a steering wheel smoothly is composed of an operating hole(12) longitudinally penetrated to a pinion shaft(10); a projection part(12a) protruded in the center of the operating hole; a recess(13) formed to the outer periphery of the pinion shaft from the operating hole; plungers(14,14a) installed at both sides of the projection part of the operating hole and provided with cutting grooves(15,15a); an elastic piece(30) installed in the recess of the pinion shaft and fitted to the cutting grooves of the plungers; and a pin(52) inserted to a hole(51) of an input shaft(50) and placed in the upper part of the projection part.
