御弁。 A cylindrical valve housing is formed with a plug mounting hole that opens into a fluid chamber that is supplied with working fluid at a predetermined pressure, and is attached to the plug mounting hole from the fluid chamber side, with one end connected to the fluid chamber and the other end connected to the fluid chamber. Valve holes are formed that open on the lower pressure side, and
A plug that is formed with a fitting part that is fitted into a plug mounting hole and a locking part that is locked to an end surface on the fluid chamber side of a valve housing, a valve body that can open and close the other end of the valve hole, and the valve body. A pressure control valve equipped with a spring that biases the valve in the valve closing direction, and a filter that covers one end opening of the valve hole and is attached to the locking part of the plug,
A pressure control valve characterized in that the filter is formed from at least one filter member and a gripping member that covers and grips the periphery of the filter member.
