PROBLEM TO BE SOLVED: To improve positioning accuracy and workability and to prevent degradation of corrosion resistance by heat in spot welding by joining components by a method excluding the spot welding, with respect to a supply and exhaust tube of a combustor. SOLUTION: In the supply and exhaust tube 2 and a supply and exhaust top 3, a recess section 35 is formed on one of the components, and a projection 37 fitted to the recess 35 is formed on the other component to join the components by a fitting method. Or a dowel 65a is formed on one of the components, and a dowel hole 65 is formed on the other component, so that the components are joined by a caulking method, thus the spot welding can be eliminated in joining of the supply and exhaust tube.
