Disclosed is a master cylinder. The master cylinder includes a hydraulic block provided with a main bore formed therein in an axial direction, a first piston having one side inserted into the main bore to be displaceable and the other side exposed to an outside of the hydraulic block and connected to a brake pedal, a second piston inserted into the main bore more inside than the first piston to be displaceable, an elastic member provided between the first piston and the second piston and configured to provide a pedal feel, and a mounting block provided with a sub bore formed therein in the axial direction and the sub bore where the first piston is inserted thereinto and passes therethrough to be displaceable and having one side coupled to the other side of the hydraulic block, wherein the hydraulic block includes at least one hydraulic flow path formed through the other side, and the mounting block includes a connection flow path allowing the sub bore to communicate with the hydraulic flow path.

Master cylinder

Disclosed herein is a master cylinder. The master cylinder according to the present embodiment includes a hydraulic block provided with a main bore formed therein in an axial direction, a first piston having one side inserted into the main bore to be displaceable and the other side exposed to an outside of the hydraulic block and connected to a brake pedal, a mounting block provided with a sub bore formed therein in the axial direction and the sub bore where the first piston is inserted thereinto to be displaceable and passes therethrough and a connection port connecting the sub bore and a reservoir, a cap provided on one side of the first piston, and a gap flow path formed by a gap between the first piston and the cap so that a first liquid pressure chamber partitioned by the first piston communicates with the connection port on the main bore.
