A relief port is provided between the small diameter piston part and the large diameter piston part, which opens into a hydraulic chamber formed in front of the small diameter piston part at a predetermined retracted position of the piston. A supply port that opens into the replenishment oil chamber that is formed is communicated with the oil tank via an oil passage formed in the cylinder body, and a valve device is interposed in the middle of the oil passage, and the valve The device includes a pressure-responsive valve that opens when the pressure in the replenishment oil chamber increases to a predetermined value or more, and a one-way valve that allows oil to flow only in one direction from the oil tank to the replenishment chamber. In the quick-filling master cylinder, the bottom of the storage hole is deepened to define a cylinder between the bottom and the switch, the cylinder is used as the oil passage, and the valve device is housed in the cylinder. A rapid filling type master cylinder characterized by:
