る車両用ブレーキ液圧制御弁装置。 A body constituting a part of a first brake hydraulic pressure circuit that connects a brake master cylinder and a wheel brake cylinder, a valve disposed within this body to control opening and closing of the brake hydraulic circuit, and a valve that controls opening and closing of this valve. A piston that is controlled in response to brake fluid pressure in a first brake fluid pressure circuit;
a spring that biases the valve to open, and a first brake hydraulic circuit and a second brake hydraulic circuit that are arranged in the body so as to be located on the outer circumferential side of the piston when the second brake hydraulic circuit is defective. In the brake fluid pressure control valve device for a vehicle, the spring is interposed between the piston and the body, and each of the brake fluid pressure circuits in the sleeve is provided with a sleeve that is actuated by a brake fluid pressure difference between the sleeves and prevents the valve from closing. The brake fluid pressure receiving surface of the brake fluid pressure receiving surface is arranged so that the sleeve operates in the same direction as the valve closing side operating direction of the piston when the second brake fluid pressure circuit is damaged, and the valve seat member of the valve is supported by the sleeve. Brake fluid pressure control valve device for vehicles.
