ABSTRACT:
A shell connecting structure as used in a brake booster for holding a peripheral bead of a diaphragm between a front and a rear shell in a hermetically sealed manner. The front and the rear shell are connected together at a location radially outward of a power piston to thereby reduce an axial size of the shells while simultaneously minimizing a radial size of the connecting portion and hence the shells.
