In a master cylinder in which a primary piston and a secondary piston define a first pressurizing chamber and a second pressurizing chamber in the cylinder body, A stem that penetrates the spring receiver of the spring and is slidably supported is fixed, a stopper is provided at the tip of the stem to regulate the maximum separation range between the secondary piston and the spring receiver, and the spring is attached to the inner wall of the cylinder body. A master cylinder characterized by being provided with a locking member that abuts a flange portion formed on a receiver to restrict backward movement thereof. 2. In a master cylinder in which a primary piston and a secondary piston define a first pressurizing chamber and a second pressurizing chamber in the cylinder body, both pistons are slidably guided in the cylinder body. and a retainer sleeve that supports the secondary cup at a position forward of the sleeve are provided in an inserted state, and a stem that penetrates the spring receiver of the return spring and is slidably supported is fixed to the secondary piston. A stopper is provided at the tip of the stem to restrict the maximum separation range between the secondary piston and the spring receiver, and a flange formed on the spring receiver is held between the retainer sleeve and the front wall of the cylinder body. A master cylinder characterized by being fixed.
