Claims

[Scope of utility model registration request]

A gas inflow path and an outflow path are formed inside, and a plug insertion portion is formed between these inflow and outflow paths. , a plug body having a gas passage formed therein, the gas passage penetrating through the inside thereof and having at least one end open to an outer circumferential surface in contact with an inner circumferential surface of the plug insertion portion, the gas passage between the inflow passage and the outflow passage; From a fully open state where the communication area through the passage is maximum, by rotating the stopper, the state changes to a half-open state, and then to a fully open state where the inflow path and the outflow path are blocked by the stopper. In the gas tank which can be switched to the gas tank, one end of the tank main body is opened to the inner circumferential surface of the plug insertion portion opposite to the end in the closing rotation direction of the opening at one end of the gas passage when half open, and the other end is opened to the outer surface. A gas tank characterized in that an air vent hole is formed that is open and is blocked from the inflow portion and the outflow path by the stopper when fully opened and fully closed.
