弁。[Claims for Utility Model Registration] A main valve is provided between the primary passage on the high pressure side and the secondary passage on the low pressure side, which opens and closes these passages and has a throttle passage on the primary side. A pressure control valve that controls the hydraulic pressure in the primary passage into two types, high pressure and low pressure, by controlling the hydraulic pressure in a chamber behind the main valve that communicates with the throttle passage, which has a pressure chamber and a piston that communicate with the chamber. A secondary throttle passage for controlling the hydraulic pressure in the chamber behind the main valve is provided between the pressure chamber and the chamber of the boost shock absorber, or between the chamber behind the piston and the secondary passage. A pressure control valve characterized by being provided with a pressure control valve.
