Claims

[Scope of utility model registration request]

A defining member which is displaceably provided within the main body of the air pressure booster and which defines two chambers, a front chamber and a rear chamber, within the main body of the device, and which controls communication and isolation of the two chambers. a valve mechanism provided therein; an input shaft provided on one side of the defining member; an output shaft provided on the other side of the defining member; and a master cylinder piston inserted in the front chamber. The defining member and the master cylinder piston are inserted between a master cylinder that is engaged with the shaft and attached to the device main body, and a spring receiver provided at the tip of the master cylinder main body and the master cylinder piston. In an assembly of a master cylinder and a pressure booster comprising a spring provided to bias the shaft side, the air pressure booster is provided in an opening of the master cylinder main body, and is connected between the opening and the master cylinder piston. covering the sealing member to be sealed and the end of the opening with a cap, caulking a part of the cap to the master cylinder body, and providing a spring receiving part on the cap;
A combination of an air pressure booster and a master cylinder, characterized in that a spring for biasing the defining member toward the input shaft is disposed between the spring receiving portion and the spring receiving portion at the tip of the master cylinder piston. Three-dimensional.
