ABSTRACT:
A brake booster provided with a function to serve as an automatic brake is disclosed. Bellows disposed within a shell has a rear bead which is axially held sandwiched between an annular recess formed in the inner periphery of a front power piston and a retainer which is a press fit over the outer periphery of a valve body. When the atmosphere is introduced into an internal space defined within the bellows to operate the brake booster as an automatic brake, the bellows tends to expand, whereby the rear bead becomes pulled axially and radially. However, a displacement of the rear bead is prevented by being held between the annular recess in the front power piston and the retainer, thereby effectively preventing a failure of a hermetic seal in the region where the rear bead is connected.
