In the case of a gas turbine, the air compressed by a compressor provided inside this gas turbine is injected into a combustion chamber provided in the turbine through an air injection valve after having passed through a first air duct, integrally formed with the main housing, and a second air duct integrally formed with the combustion chamber housing. One end of the first air duct is funnel-shaped, so that the air compressed by the compressor can enter the first air duct with high efficiency. Since the air flowing through the air duct according to the present invention is heated as it flows along the combustion chamber it is possible to improve the combustion efficiency.
