Abstract
An assembly of a vacuum booster device and a master cylinder comprising a booster shell composed of front and rear halves and a brake master cylinder body which are together combined by the aid of tie rods extending through the booster shell, and a booster piston accommodated in the shell so that the load on the booster shell is removed, any means for fastening the opposite edge portions of both the shell halves is eliminated and, accordingly, outside diameter of the shell is decreased without lowering its strength. Furthermore, retaining ring fitted in the tie rod effective in preventing the shell from separation enables both the constructing and separating works of the assembly easier.
