[Background of device]

 Conventionally, there is a portable stove that can be carried in a camp where a small, removable gas cylinder is used as fuel. In addition, this product is aimed to be thinner so that it is more portable, and as a result, and because the flame of the burner acts more efficiently on the heated object, the installation height is lower even in Gotoku that supports the heated object. Tend to design.

However, the above-mentioned Gotoku, which has a low height, is good when, for example, a pot is used, but when a relatively large iron plate is placed and heated, the upper surface of the Gotoku is almost covered. The radiant heat of the iron plate is transferred to the cylinder without escaping to the outside. As a result, the cylinder overheats abnormally, the internal pressure in the can rises, and there is a risk of gas leakage and gas cylinder explosion. Therefore, there is one in which a pedestal S for using an iron plate as shown in FIG. 11 is separately provided, but if it is a separate member, it is easy to lose it, and if the number of parts is large, it is easy to misuse the method. There was a fear.
