Claims

[Claims for Utility Model Registration] In a gas tank that opens and closes the gas passage 2 by rotating the valve 3 and has a so-called lock mechanism, which is a mechanism that prevents the gas passage 2 from being easily changed from the closed state, A slit hole 13 is provided in the upper peripheral wall 10 of the main body 1, and a rod-shaped lever 15 is slidably passed through the slit hole 13 through the rotation shaft 9 for rotating the valve 3, and the tip 17 of the lever 15 is formed with a slit. The rear end 1 of the lever 15 is made to protrude from the hole 13 to the outside of the main body 1.
A spring seat 21 is formed near the lever 15, and a spring 22 is attached to the lever 15 to urge the spring seat 21 and the rotation shaft 9 in a direction that widens the distance between them. The gas tank is characterized in that a lock hole 25 is provided in the upper circumferential wall 10 of the main body 1, into which the rear end 19 of the lever 15 is fitted by the biasing force of a spring 22 only when the gas passage 2 is closed by rotating the gas passage 2.
