Abstract

PURPOSE: To prevent a damage of rolling diaphragm caused by an adhesion thereof, provide a light weight unit as well as improve a durability of the unit by a method wherein the front and rear walls of the shell are connected by a tie rod passing through a booster piston, the rolling diaphragm arranged between said piston and the rod is always bulged out.
CONSTITUTION: The opposing front wall 1F and rear wall 1R of the booster shell 1 are connected through the tie rod 34 passing through the booster piston 2, the flange 40 of the master cylinder M and the front wall 1F are fixed with each other by the bolt 37 at the front end of said rod, the rear wall 1R is fixed by the flange 45 at the rear end of the rod and the flange 44 of the bolt 43 and further to the front wall W of the compartment by the bolt 31. The rolling diaphragm 35 is arranged in tension between the opposing circumferential surfaces of the piston 2 and the rod 34. The movable stopper plate 25 is adjusted to forward the input rod 11, the control valve 5 is operated to feed surrounding air into the chamber B, the piston 2 is forwarded, and then the movable stopper plate 25 is locked by the nut 26 when the output rod 22a is slightly contacted with the operating piston 59. As a result, the diaphragm 35 is apt to be bulged out.
