置。 The inside of the housing is divided into a constant pressure chamber connected to a negative pressure source by a power piston and a variable pressure chamber connected to negative pressure or the atmosphere, and the variable pressure chamber is incorporated inside the power piston and switches in response to pedal depression. In the negative pressure booster, which is connected to negative pressure when the pedal is not depressed and connected to the atmosphere when the pedal is depressed by an actuated valve mechanism, the constant pressure chamber and the variable pressure chamber are configured not to communicate through the power piston. In addition, the valve mechanism is provided with a passage which is cut off from communication with the atmosphere when the pedal is not depressed, and which is constituted by the variable pressure chamber, and which is cut off from communication with the variable pressure chamber and the atmosphere when the pedal is depressed, and the passage is kept under negative pressure. A negative pressure booster characterized in that it is connected to an electromagnetic switching valve that can be connected to a source or the atmosphere.
