Abstract
A booster, for use as an automotive brake booster is disclosed which works quickly at the beginning of an operation sequence. The booster has a housing with a piston capable of sliding in the opening of the housing and acting on a diaphragm dividing the inside of the housing into a constant pressure chamber and a variable pressure chamber. An output rod is provided having a rear end portion inserted in the power piston. A reaction disk is mounted between the output rod and the power piston with a retainer mounted on the power piston on the side of the constant pressure chamber. The retainer prevents the output rod from coming off and also causes the output rod to push the reaction plate toward the piston.
