The detaching member 14 is provided upright and the working end 17 of the detaching member 14 is provided.
Is set so that the shoulder 20 on the front of the gas cylinder 1 is pushed backward. Reference numeral 21 indicates a holder into which the detaching member 14 is inserted and held, and 22 indicates a stopper for stopping it. The detaching member 14 used in each of the above examples is formed of a shape memory material, and does not push the gas cylinder 1 at room temperature or within a set range, but when the temperature exceeds a set temperature, the detachable member 14 is deformed into a stored shape and is magnetically held by pushing the gas cylinder 1. The shape and the mounting position are set so that it is removed. Such a removal member
14 is formed in a rod shape or a plate shape, and is fixed only at one end.

温度が異常に上昇した場合に作動する。(Operation) In the apparatus of the present invention configured as described above, the gas cylinder 1 is connected to the connection port 10 of the governor 9, and the flange 3 is attached to the magnetic holding mechanism 11 while being held by the magnetic attraction force. If the temperature around the gas cylinder rises abnormally due to abnormal handling during operation, it will operate.

ら離されるので、バルブノズル４が突出してガスが吐出
しなくなり、燃焼を停止させるのである。That is, when the temperature rises above the set value, the detaching member 14 is deformed into a pre-stored shape, and its working end portion 17 pushes up the rear portion of the gas cylinder 1 from below against the magnetic attraction force, or in front of the gas cylinder 1. Since the portion is pushed backward against the magnetic attraction force, the gas cylinder 1 held by magnetism can be removed. At this time, since the gas cylinder 1 is separated from the connection port 10, the valve nozzle 4 projects and the gas is no longer discharged, so that the combustion is stopped.
故にそれ以上の温度上昇はなくなり、安全性が保たれる
訳で、周辺温度が下がり、取外し部材14も設定温度以下
になれば原形に復原するのでガスボンベ１を再び装着す
ることができる。Therefore, there is no further temperature rise, safety is maintained, the ambient temperature drops, and the removal member 14 is restored to its original shape when the temperature falls below the set temperature, so that the gas cylinder 1 can be mounted again.

る。(Effects) Since the present invention has the above-described structure and action, even if the gas cylinder is heated due to abnormal handling of the gas appliance, the detaching member is deformed when the preset value exceeds the preset value, the gas cylinder is pushed, and the magnetic adsorption is performed. Since the connection is disconnected against the force and the valve nozzle projects and opens, the combustion cannot be continued, and therefore the temperature does not rise any more. Therefore, the gas cylinder 1 held by the magnetic attraction force is removed. The effect is that it can be securely removed and high safety can be obtained.
