Abstract
A master cylinder includes a cylinder body including a cylinder portion, a piston fit into the cylinder portion so as to fluid-tightly divide the cylinder portion into a pressure chamber and a supply chamber, a connecting passage which is disposed in the piston and which connects the pressure chamber with the supply chamber, a valve mechanism which is mounted on the piston and which disconnects the connecting passage when the piston is moved for a predetermined distance and a restriction member installed in the connecting passage for restricting a flow of a fluid from the pressure chamber into the supply chamber when the piston is operated and allowing the flow of the fluid from the supply chamber into the pressure chamber when the piston is returned.
