HYDRAULIC PRESSURE CONTROL VALVE

PROBLEM TO BE SOLVED: To provide a hydraulic pressure control valve capable of quickly supplying oil to a damper oil chamber not to produce action delay of the damper oil chamber in an early period of action without restriction on installation. SOLUTION: In the hydraulic pressure control valve provided with a linear solenoid part S, a spool 22 driven forward by output of the linear solenoid part S, a valve body 20 having the spool 22 fitted in, and a return spring 23 energizing the spool 2 in a retreat direction, and having a reaction oil chamber 35 in which hydraulic pressure pressing the spool 22 to opposing output of the linear solenoid part S is introduced from an output port 38 and a damper oil chamber 36 damping the spool 22 provided on the valve body 20, the valve body 20 is provided with the damper oil chamber 36 adjoining the reaction force oil chamber 36 with putting a third land part 253 therebetween, and a sliding gap g capable of leaking and supplying oil from the reaction force oil chamber 36 to the damper oil chamber 36 is provided between the third land part 253 and the valve body 20.
