PROBLEM TO BE SOLVED: To provide a gas supply valve allowing durable and precise displacement of a closing part even when sufficiently large stress acts thereon. SOLUTION: This gas supply valve is provided with: a valve seat 1; the closing part 2 pressed against the valve seat 1 at a closing position; and a rocking arm 3 pressing the closing part 2 against the valve seat 1. The closing part 2 can be displaced from an opening position to the closing position by arranging a transmission plate 4 between the closing part 2 and the arm 3 to slide the arm 3 or a transmission element 5 arranged on the arm along the transmission plate 4 in rocking the arm 3.
