Abstract
PURPOSE: To narrow the width of casing as much as possible by withdrawing the boss portion in the front of a power piston into a bore in the rear end of a master cylinder for securing the working stroke of the power piston.
CONSTITUTION: The rear end of a master cylinder 21 is inserted into an opening 26 at the central part of the frontal face of a casing 1 and a flange 24 is supplied into the casing 1 by means of bolt and nut 25. And, the outside diameter D1 of a boss 19 at the central part of the power piston 3 facing the end of the cylinder 21 is made smaller than the inside diameter D2 of the cylinder bore so that the boss 19 can enter the bore of the cylinder 21 when the power piston 3 is working. Thus, working stroke necessary for the power piston 3 can be secured.
