PROBLEM TO BE SOLVED: To provide a combustion assisting tool with a combustion air guide vane evenly heating a pan and improving heat efficiency by eliminating a blow-up of combustion air, extending a residence time of the combustion air in a combustion tube, raising a rising temperature more higher, and evenly agitating the combustion air to carry out combustion. SOLUTION: The combustion air guide vane 2 is bent toward an outer side of the combustion tube 1 to eliminate a loss of energy due to a blow-up of the combustion air in a combustion tube 1 interior, improve combustion efficiency, and extend a service life of a product. By utilizing that the combustion air guide vane 2 opens outward by itself when cylindrically forming the combustion tube 1 if it is slantly cut, a process of bending the combustion air guide vane 2 is omitted. The product is made by shaping the combustion tube 1 in a truncated cone shape which can be stacked to reduce volume during product conveyance. COPYRIGHT: (C)2006,JPO&NCIPI
