ブレーキブースタ装置。 A power piston that is movable between the front shell and the rear shell, a check valve that is provided on the front shell and connected to the engine vacuum, and a valve that is connected to the rear shell to introduce either atmospheric air or engine vacuum into the rear shell. a valve plunger forming a valve plunger, an operating rod that pushes the valve plunger, a push rod that is connected to the master cylinder of the brake and pushes back the valve plunger by the reaction force of the master cylinder, and communicates with the valve formed by the valve plunger and the valve plunger. a connecting pipe connected to the connecting pipe and switching between atmospheric pressure and engine vacuum; an operating circuit that operates the solenoid valve; and a vehicle speed sensor that detects when the vehicle speed has fallen below a certain level. A brake booster device comprising: an accelerator switch that operates when the accelerator pedal is released; and a discrimination circuit that operates the operating circuit depending on opening and closing of the vehicle speed sensor and the accelerator switch.
