荷重液圧制御弁。[Claims for Utility Model Registration] A rod connected to the lower part of the piston protrudes from the lower part of a hydraulic control valve body having a control piston, and a lever for transmitting the load of an automobile is freely rotatable below the rod. In the variable load hydraulic pressure control valve, the rod is slid by the lever, and an elastic annular boot is fitted between the peripheral edge of the protruding hole of the rod of the main body and the rod. A groove is formed on the surface of the boot that comes into close contact with the rod or the surface that comes into close contact with the peripheral edge, one end of the groove opens into the inside covered by the boot, and the other end has a groove. A variable load hydraulic pressure control valve characterized in that the depth of the groove gradually decreases toward the outside and closes before the outside.
