Claims

[Scope of utility model registration request]

It is equipped with a cylinder having a hydraulic pressure supply path and a hydraulic pressure discharge path, a power piston slidably fitted into the cylinder, and a bushing rod linked to the power piston, and the cylinder has a hydraulic pressure of the power piston during brake rotation. In a brake booster configured to cause a bushing rod to perform a braking action on a mask cylinder by forward motion, each of the power piston and the bushing rod is provided with each return that constantly urges them in a direction opposite to the mask cylinder. A brake booster characterized by being provided with a spring.
