PROBLEM TO BE SOLVED: To provide a combustion device comprising a leg structure capable of being easily assembled and having high durability. SOLUTION: This leg structure 30 for loading a fuel tank 20 has a pair of right and left frames 32a, 32b supporting the fuel tank 20, and wheels 47a, 47b mounted on front parts of the frames. The wheels 47a, 47b are respectively held between step portions 41a, 41b at both ends of an axle 42 held by the right and left frames 32a, 32b, and the right and left frames 32a, 32b. Further, the right and left frames 32a, 32b are connected through the fuel tank 20 so that they do not expand right and left. The wheels 47a, 47b are disposed inside of the right and left frames 32a, 32b. COPYRIGHT: (C)2007,JPO&INPIT
