Claims

[Scope of Claim for Utility Model Registration] A check valve that is provided in a passage communicating between the master cylinder and the wheel cylinder and allows the flow of brake fluid from the wheel cylinder to the master cylinder, and a check valve that is slidably fitted into the housing. The brake fluid pressure generated in the master cylinder is applied to the plunger with a small pressure-receiving area upstream of the check valve. and a proportion valve that acts on a plunger with a large pressure-receiving area downstream of the check valve, reduces braking fluid pressure according to the ratio of both pressure-receiving areas, and supplies it to the wheel cylinder; and a wheel side member, the ring mechanism adjusts the hydraulic pressure at which the proportion valve starts operating by applying a biasing force to the plunger according to a change in the gap between the vehicle body side member and the wheel side member. , a piston that is slidably provided in the housing of the proportion valve and that displaces the plunger in the axial direction to adjust the biasing force of the plunger by the link mechanism; and a piston that controls fluid pressure to adjust the height of the vehicle. and a vehicle height adjustment device that selectively adjusts the vehicle height to a plurality of height positions, and when fluid pressure from the vehicle height adjustment device is applied to the piston and the fluid pressure is varied to change the vehicle height. The biasing force from the link mechanism that changes with changes in vehicle height is compensated for by the displacement of the piston, and the biasing force acting on the plunger is substantially reduced before and after the vehicle height is changed by the vehicle height adjustment device. A load-responsive braking hydraulic pressure control device that maintains constant pressure.
