Zusammenfassung:	PURPOSE:To achieve the enhancement in turbine efficiency by making the outside diameter of the moving blade inlet part of the disk larger than the outside diameter of the nozzle blade outlet part of a nozzle inner ring, and forming a taper part on the outer circumferential part of the disk facing the nozzle inner ring side. CONSTITUTION:The outside diameter D4 of the moving blade 24 inlet part of a disk 26 is made larger than the outside diameter D3 of the nozzle blade 21 outlet part of a nozzle inner ring 22. Further, a taper part 30 is formed on the outer circumferential part of the disk 26 facing the nozzle inner ring 22 side. Thus, the secondary flow losses which world be caused on the disk inner ring side can be reduced, enabling the enhancement in turbine efficiency.
