Claims

[Claims for Utility Model Registration] A valve body having a valve seat portion, a cap covering the upper part of the valve body, and a spring installed in a spring chamber defined by the cap and the valve body in the valve closing direction. A valve device including a valve body that is biased and combined with the valve seat portion is housed in a storage portion formed at the bottom of the reserve tank and positioned above the bottom surface of the reserve tank, and the valve device is placed above the bottom of the reserve tank. A communication means is provided on the side wall of the valve body to directly communicate the inside of the reserve tank with the inlet to the liquid passage that communicates the cylinder side and the spring chamber through a seat hole provided in the valve body. The sealing member of the valve device is composed of a fixed part and a lip part extending downward from the fixed part, and is formed using a highly elastic material, and the fixed part is attached to the outer peripheral part of the valve body. and a quick-filling type master cylinder, characterized in that a leg part for attaching the reserve tank to the cylinder body is provided below the storage part, protruding downward from the bottom of the reserve tank and integrated with the reserve tank. Valve structure.
