Pressure control valve

Abstract

To provide a pressure control valve capable of suppressing lateral vibration of a valve body and reducing cost of an elastic member.SOLUTION: A pressure control valve 100a comprises; a main valve body 10; a valve body 20; a guide member 60 that extends in an axis L direction, has a plurality of support parts 62 disposed on the same circumference as viewed from the axis L direction, is fixed to the valve body 20, and guides movement of the valve body 20 in the axis L direction by being brought into slidable contact with an inner peripheral surface 12b of the main valve body 10; and an elastic member 70, which is a different body from the guide member 60, fixed to the guide member 60, and biasing the guide member 60 in one direction orthogonal to an axis L. At least one of the plurality of support parts 62 is a constant abutting part 62a that constantly abuts on the inner peripheral surface 12b of the main valve body 10 with biasing force by the elastic member 70. Thereby, a conventional problem 1 (generation of lateral vibration of the valve body) and a conventional problem 2 (high cost of the elastic member) can be solved.SELECTED DRAWING: Figure 1
