PROBLEM TO BE SOLVED: To provide a rotor for a turbine, in which a turbine disc can be partially replaced, and in which moving blades can be easily provided in a corresponding number of stages to turbine output. SOLUTION: A turbine disc part 2 is separated into stages to compose disc units 2A, 2B, ..., 2n, 11A, 11B, ..., 11n, where the disc units are detachably connected to each other. As the disc units are thus separated from each other to be detachably connected, the disc units corresponding to a damaged part need only be replaced when the moving blades or disc units are partly damaged. By adjusting the number of the disc units connected, the moving blades can be easily set in a corresponding number of stages to turbine output. COPYRIGHT: (C)2005,JPO&NCIPI
