In a master cylinder that is movably assembled, the guide bushing has a through hole that communicates the inner circumference and the outer circumference, and a communication passage that communicates the entire outer circumference of the guide bushing with a tank storing brake fluid, the cylinder hole A mounting hole for the seal member and the guide bushing is formed on the primary piston mounting side of the primary piston, and an end face groove is provided on the outside of the mounting hole to form a gap for liquid supply when a cap member is attached to the end surface. A master cylinder characterized in that a through hole communicating with a tank connection port is formed and opened in the axial direction in the end groove.
