を特徴とする急速充填型マスタシリンダ。 The cylinder body is provided with a stepped cylinder hole consisting of a small diameter portion at the front and a large diameter portion at the rear, and a piston having a small diameter piston portion and a large diameter piston portion opposing the small diameter portion and the large diameter portion, respectively, is provided in the cylinder hole. At a predetermined retracted position of the piston, a relief port opens into a hydraulic chamber formed in front of the small diameter piston section, and a relief port opens into a replenishment oil chamber formed between the small diameter piston section and the large diameter piston section. The supply port is communicated with an oil tank attached to the vehicle body via a hose, and a valve device is interposed in the middle of the hose, and the valve device is configured to increase the pressure in the supply oil chamber to a predetermined value or more. 1. A quick-filling type master cylinder comprising: a pressure-responsive valve that opens when the oil tank is turned on; and a one-way valve that allows oil to flow in only one direction from the oil tank to the replenishment oil chamber.
