Claims

[Scope of Claim for Utility Model Registration] A body having a brake mask cylinder connection port and a rear wheel brake cylinder connection port, one end of which and the other end with a diameter smaller than this are fitted into the inner cavity of the body. , a first liquid chamber having one end surface exposed in the body and communicating with the brake mask cylinder connection port, an air chamber having the other end surface exposed, and an annular valve portion between both ends thereof being exposed and the rear a second annular fluid chamber communicating with the wheel brake cylinder; a first fluid chamber supported by the body and cooperating with the annular valve portion;
a third annular valve communicating with the second liquid chamber and the brake mass cylinder connection port through the inner hole of the annular valve seat member;
a hydraulic response piston, which is divided into a liquid chamber and further has a communication passage therein that is open at one end surface and communicates between the first liquid chamber and the second liquid chamber; a spring installed in the first liquid chamber to bias the hydraulic pressure-responsive piston toward the first liquid chamber so that the annular valve part is separated from the first annular valve seat member; When is less than a predetermined value, the vehicle assumes a rest position in contact with a stopper provided on the body and is separated from the second annular valve seat member fixed to one end of the hydraulic pressure responsive piston, and the vehicle deceleration reaches the predetermined value. a spherical inertia-responsive valve element that rolls into contact with the second member to cut off communication between the communication passage and the first liquid chamber when the load exceeds the yt load of the spring. In a state where the hydraulic pressure responsive piston is held at or near its rest position when the hydraulic pressure is lower than the hydraulic pressure value that causes the vehicle deceleration of the predetermined value, and when the hydraulic pressure is lower than the hydraulic pressure value that causes the Ichikawa deceleration of the predetermined value when the volume is constant. A braking hydraulic pressure control device for a vehicle, wherein the hydraulic pressure responsive piston is configured to slide in a low pressure state.
