PROBLEM TO BE SOLVED: To enable to adjust a gap between a guide ring and a moving blade with a simple means without impairing turbine output and efficiency. SOLUTION: This turbine is provided with a housing 11 and a rotor 12. A plurality of rows of stationary blades 13 are provided in the housing 11 and a plurality of rows of moving blades 14 are provided on the rotor 12. The guide ring 18 is arranged between two rows of the stationary blades 18 in the axial direction of the housing 11 and the gap 21 is formed between the guide ring 18 and the moving blade 14. Displacement of the guide ring 18 is adjustable for adjusting the gap 21. Size of the gap 21 is set by displacement adjustment of the guide ring 18 and optimized for each using condition. |
