In order to suppress the inclination of a and 1b to be small, when the above-mentioned lap margin L of the through hole 8b has a large structure, there is a problem that the product itself becomes large and the cost increases. Also,
Even if the lap length L is made large, a slight inclination occurs, so that the sealing materials 5a, 5b of the valves 1a, 1b cannot evenly contact the tapered surfaces 6y 1 of the valve bodies 3a, 4a to seal. However, there is a problem that fluid leakage easily occurs.
