するプロポーシヨニングバルブ。 A first pressure chamber that communicates with the rear wheel output port of the master cylinder and urges the piston toward one of the cylinders in the cylinder by means of a piston; a second pressure chamber that communicates with the output port and urges the piston toward the other cylinder; a third pressure chamber that communicates with the first pressure chamber; and a third pressure chamber that communicates with the rear wheel cylinder and urges the piston toward the other cylinder. a fourth pressure chamber that urges the other pressure chamber, and a valve mechanism is disposed between the third pressure chamber and the fourth pressure chamber, and a spring forces the piston into one of the cylinders. , the valve mechanism is opened with the master cylinder inactive, and after the master cylinder is activated and the pressure in the rear wheel cylinder reaches a certain pressure or more, the valve mechanism is closed. A proportioning valve that increases pressure in a rear wheel cylinder while opening, characterized in that a passage communicating between the first pressure chamber and the third pressure chamber is formed in the piston.
