At a predetermined retracted position of the piston, a relief port opens into a hydraulic chamber formed in front of the small diameter piston part and a replenishment oil chamber formed between the small diameter piston part and the large diameter piston part. A supply port is connected to an oil tank via an oil passage provided with a valve device, and the valve device includes a pressure-responsive valve that opens when the pressure in the supply oil chamber rises to a predetermined value or more, and the oil tank. a one-way valve that allows oil to flow only in one direction from the supply oil chamber to the supply oil chamber; and a flow path resistance that bypasses the pressure-responsive valve and the one-way valve to communicate between the oil tank and the relief port. a large bypass; A quick-filling master cylinder comprising a valve body provided in the valve case facing the valve body, and a valve spring provided in the valve case to urge the valve body toward the valve seat. 1. A quick-filling master cylinder, characterized in that the valve body is provided with a friction member that slides on the inner circumferential surface of the valve case and slows at least the closing operation of the valve body.
