[Claims for Utility Model Registration] A cylinder body, a pair of pistons slidably disposed within the cylinder body, and a cylinder formed between one piston and the bottom wall of the cylinder body and between both pistons. a pair of pressure chambers; a communication passage provided in one of the pistons and communicating the one pressure chamber with the reservoir via the supply port of the cylinder body; and a communication passage located between the other pressure chamber and the reservoir. a port provided in the cylinder body and opened and closed as the other piston slides; and a port inserted into the one piston at one end so as to be relatively movable so as to maintain liquid tightness between the two pressure chambers. a rod connected to the other piston at the other end; a valve provided on the one piston and capable of opening and closing the communication passage in accordance with relative movement between the rod and the one piston; includes a spring that holds the valve in a position where the communication passage is opened and holds both pistons in a non-operating position, and sets a lift amount of the valve to be smaller than a piston stroke for opening and closing the port. The master cylinder is characterized by:
