PURPOSE: A master cylinder is provided to minimize brake releasing delay by connecting a through-hole and a flow path of an oil tank. CONSTITUTION: A master cylinder comprises a cylinder main body(20), a piston(30), and a sealing member. The cylinder main body comprises an oil inflow hole(25) and a liquid pressure chamber(23). The piston comprises through-holes which connects an oil inflow hole and a liquid pressure chamber and increases the pressure of the inside of the liquid pressure chamber. The sealing member is formed between the cylinder main body and the piston and selectively blocks the circulation of the oil through the through-hole of the piston. |
