Claims

[Scope of utility model registration request]

A cylindrical valve housing is formed with a plug mounting hole that opens into a fluid chamber supplied with working fluid at a predetermined pressure, and is attached to the plug mounting hole from the fluid chamber side, with one end in the fluid chamber and the other end. A plug in which a valve hole is formed that opens on the low pressure side from the fluid chamber, a valve element that can open and close the other end of the valve hole, a spring that biases the valve element in the valve closing direction, and a valve hole. In a pressure control valve equipped with a disk-shaped filter that covers an opening at one end, the plug has a fitting portion that is fitted into the plug mounting hole, and a fitting portion that is approximately the same diameter as the valve housing and is located on the fluid chamber side of the valve housing. 1. A pressure control valve comprising: a locking portion that is locked to an end face; and the filter is mounted on the locking portion.
