Abstract
A portless-type master cylinder for use in an automotive fluid brake system has a supporting means which resiliently supports the end of a piston adjacent to a push rod so as to preserve a predetermined gap between the end of a valve rod and a stopper member when the master cylinder is not operating. With this arrangement, the wasteful stroke is minimized and the impact at the time of start-up of the master cylinder is reduced.
