PROBLEM TO BE SOLVED: To make the structure of an air distribution controller simple by making such an external motive power source as electricity, hydraulic pressure, etc., unnecessary by using the compressed air from a compressor as a motive power source. SOLUTION: A gas turbine combustor mixes part of the compressed air supplied from a compressor with fuel as combustion air and burns the mixed gas. On the other hand, the combustor mixes the remaining part of the compressed air from the compressor with a combustion gas as dilution air and supplies the diluted combustion gas to a turbine. In this case, the flow rate of the combustion air is controlled in accordance with the output of the turbine by providing air distribution changing mechanisms 8, 9, 10, and 14 which change the distributing ratios for combustion and dilution of the compressed air from the compressor and driving mechanisms 21-27 which drive the mechanisms 8-10 and 14 in accordance with the pressure or temperature of the compressed air by using the compressed air from the compressor as a drive power source.
