PROBLEM TO BE SOLVED: To optimize a mixing ratio of fuel and compressed air in a combustor cylinder and improve exhaust gas components by fixing an inner cylinder disposed in an outer cylinder which is attached to a turbine casing, to the outer cylinder through a flow equalizing member. SOLUTION: An inner cylinder 11 is disposed in an outer cylinder 15 while being integrally fixed to a flow control member consisting of a swirl plate 19 which is fixed to the outer cylinder 15. A fuel injection nozzle 12 and a swirler 13 are fixed to a cover 14 with a bolt at an upper portion of the inner cylinder 11. Compressed air passes from inside a turbine casing 18 through the swirl plate 19 to bring about one directional large swirling flow by the swirl plate 19, and directed to the inner cylinder 11 via air intake ports 11-1 at the upper portion of the inner cylinder and via the swirler 13. The fuel which has been supplied from outside and injected from the fuel injection nozzle 12 is mixed, at an appropriate mixing ratio, with the compressed air which has passed through the air intake ports 11-a and the swirler 13.
