The catalytic combustion device 17 has the following configuration. The gas cylinder 6 includes a gas opening / closing valve 7, and the gas opening / closing valve 7 is opened / closed by operating an opening / closing knob 8. Reference numeral 9 is an opening / closing spring that biases the gas opening / closing valve 7 in the opening direction. The gas discharged from the gas cylinder 6 by operating the opening / closing knob 8 is ejected from the gas ejection nozzle 10 and flows through the inside of the ejector 12 together with the air sucked from the air intake port 11 by the suction effect of the gas flow ejected from the gas ejection nozzle 10. Flowing. 13 is a combustion catalyst, 14 is an ignition device,
Reference numeral 15 is a mixed gas ejection port, which supplies the mixed gas to the combustion catalyst 13. Reference numeral 16 is a protective cylinder for protecting the combustion catalyst 13 and also serves to make the catalyst combustion heat uniform.

The heat generation control means 19 comprises a bimetal 20, an operating piece 21, and a bimetal fastener 22.

The operation of this embodiment will be described below. When the opening / closing knob 8 is operated to open the gas opening / closing valve 7, the gas ejected from the gas cylinder 6 via the gas ejection nozzle 10 is mixed with the air sucked from the air intake 11.
It becomes a combustible mixed gas. Next, when the ignition device 14 is operated, the mixed gas starts flame combustion and the combustion catalyst 1 is instantaneously generated.
3 is raised to a temperature at which catalytic combustion is possible. The catalytic combustion heat is uniformly radiated by the protective cylinder 16. This catalytic combustion heat is also transferred to the bimetal 20. Therefore, the bimetal 20 thermally expands. Since one end of the bimetal 20 is fixed by the bimetal fastener 22, the bimetal 20 linearly expands so as to push the operating piece 21.
