Abstract: A braking device for a vehicle includes a cylinder, a master piston having a pressure applying piston portion and a servo pressure receiving portion, an input piston, a pressure accumulating device, a pilot pressure generating device, and a regulator having a first piston slidably fitted into a housing and dividing an inside of the housing into a first pilot chamber and a servo pressure generating chamber, a valve mechanism connecting the servo pressure generating chamber with the pressure accumulating device or a reservoir in response to movement of the first piston, and a second piston fitted into the housing and dividing the inside of the housing into the first pilot chamber and a second pilot chamber, wherein the second piston is formed so that an end surface thereof exposed to the first pilot chamber has a larger pressure-receiving surface area than an end surface exposed to the second pilot chamber.

Abstract: A vehicle brake device is provided with a regulator for generating a servo pressure acting on a master piston in a master cylinder, based on a pilot pressure. The regulator is provided with a brake fluid absorbing section communicating with a first pilot chamber for absorbing the brake fluid as the pilot pressure in the first pilot chamber in the quantity depending on the fluid pressure in the first pilot chamber. The brake fluid absorbing section comprises a piston receiving portion formed in a second piston and opening to the first pilot chamber, a pressure receiving piston slidably received in the piston receiving portion and making the first pilot chamber variable in capacity, and an urging member urging the pressure receiving piston toward the first pilot chamber side.
