PROBLEM TO BE SOLVED: To reduce abrasion of a turbine, and improve life of parts. SOLUTION: This turbine 1 is provided with a compressor 3, a combustion chamber 5, and a turbine part 7 comprising a plurality of turbine stages disposed along a rotor 2 in rotation symmetry that is rotatably supported to rotate. Each turbine stage 15 includes a moving vane 17 and a stationary vane 16 washed by high temperature medium 13 to cooperate with each other. Cooling medium supplied from the compressor 3 to cool the moving vane 17 and the stationary vane 16 flows along the rotor 2 from the compressor 3 to the turbine part 7 through a passage, where liquid is introduced into the cooling medium for cooling. The passage is extended on the outer side of the rotor 2, and the liquid is introduced into the passage in a close range to the compressor 3. COPYRIGHT: (C)2004,JPO
