PROBLEM TO BE SOLVED: To provide the combustor of a gas turbine capable of being reliably fixed at the combustor and easily assembled. SOLUTION: In the combustor having a cylindrical side wall provided at one end with a fuel injection valve, the cylindrical side wall of the combustor is formed that a plurality of concentric cylinder members are intercoupled and a coupling member making contact with the end face and the inner peripheral surface of the cylinder member for fitting-in is located between the adjoining cylinder members. An air hole is formed on the fuel injection valve side of the end parts of a plurality of the cylinder members and in the vicinity of the end part in which the coupling member is fitted. A small part is situated at the end part, situated on the opposite side to the fuel injection valve, of the coupling member. An annular groove is formed between the outer peripheral surface of the small part of the coupling member and the inner peripheral surface of the cylinder member. Air entering in the combustor through the air hole flows through the groove along the side wall of the cylinder member and cools the side wall of the cylinder member from the inside.
