PURPOSE: A clutch master cylinder is provided to minimize clearance between a magnet and a piston by combining the magnet with the piston through a fastening means. CONSTITUTION: A clutch master cylinder includes a piston(120), a push rod, a magnet, a magnet sheet(170), and a sensor. The piston is inserted into a cylinder. The push rod is connected to the piston and transfers power. The magnet is located on one end of the piston. The magnet sheet combines the magnet with the piston at the opposite side of the piston. The sensor is located outside the cylinder and senses the movement of the piston according to interaction with the magnet.
