ABSTRACT:
A brake booster is disclosed which functions as an automatic brake as required. Bellows is disposed within a constant pressure chamber of the brake booster, and has a front end which is connected, by a first support member, to a bulge which is formed in the axial portion of a shell. A seal member is connected to the outer periphery of the first support member, and is held in abutment against the wall surface of the shell at a location radially outward of an inlet for the atmosphere. A communication channel is formed by a space between the first support member and an opposing wall surface of the shell and the bulge and the like. A communication is established between the internal space of the bellows and the inlet through the communication channel. This construction allows the overall length of the brake booster to be reduced as compared with the prior art in which a spacer is provided outside the shell.
