Claims

[Scope of utility model registration request]

The housing is provided with an inlet for mask cylinder hydraulic pressure and an outlet to the rear wheel cylinder (inside the housing, there is a deceleration sensing valve on the inlet side, and a mask cylinder hydraulic pressure is supplied to the wheel cylinder on the outlet side). A P-valve piston that opens and closes the valve and a hydraulic pressure in a control chamber into which the master cylinder hydraulic pressure flows are provided, and the valve is moved by the hydraulic pressure of the control chamber into which the master cylinder hydraulic pressure flows, and comes into contact with one end surface of the P-valve piston to open and close the valve. A control plunger is provided to push the piston in the opening direction of the valve, and when the deceleration of the vehicle reaches a predetermined value, the deceleration sensing valve is closed to block mask cylinder hydraulic pressure from flowing into the control chamber. A deceleration sensing type hydraulic pressure control device, characterized in that a cushion is attached to one of the contact surfaces of the control plunger and the P valve piston.
