Zusammenfassung:	PROBLEM TO BE SOLVED: To permit all of compressed air to be used for cooling a scroll by forming a compressed air channel between a scroll body and a scroll housing, allowing the entrance end of the channel to communicate with the exit of a compressor and releasing the exit end of the channel toward a combustor side. SOLUTION: An annularly formed scroll 30 comprises in its inside space 38 a scroll body 31 for having combustion gas flowed therein and a scroll housing 32 partially enclosing the body. One portion of the body 31 communicates with a combustor while the other portion is connected to guide scrolls 34, 35. A channel 100 having a given sectional area serves as a high pressure air passage passing a compressor with its exit end 100b being released toward a combustor side X of a gas turbine, partially enclosing the body 31. A portion 31a which is not enclosed by the channel 100 is provided with an auxiliary housing 40 for cooling and the portion 31a is thus cooled.
