したことを特徴とするコツク。 A valve chamber with a cylindrical inner peripheral wall is provided in the synthetic resin body, and a connection port communicating with the valve chamber through a valve hole is provided in the outer peripheral wall of the body, and the valve chamber rotates while maintaining watertightness in the valve chamber. Insert a sleeve-shaped synthetic resin valve body, form a liquid passage hole in the peripheral wall of this valve body that matches the connection port above, and connect the valve shaft connected to one end of the valve body from one end of the Kotoku body. The valve body is made of nylon and protrudes outward, has a handle attached to the valve stem, and has a liquid inlet at the other end of the body that communicates with the opening formed at the other end of the valve body. The inner diameter of the area extending from the end of the valve body on the liquid inlet side to the vicinity of the passage hole is made larger than that of other parts, so that the wall thickness of that part is reduced compared to other parts of the valve body. This valve is characterized by being thinner than the wall thickness of the valve, and that part is used as a sealing part that comes into close contact with the inner peripheral wall of the valve chamber due to the pressure of the liquid.
