PROBLEM TO BE SOLVED: To provide a method reducing a cutting amount as much as possible to enable labor saving of correction work, in work for correcting rotation balance of an impeller rotor, and provide the impeller rotor.SOLUTION: An impeller rotor 21 includes a turbine impeller 11, a compressor impeller 12, a shaft 13 connecting the turbine impeller 11 and the compressor impeller 12 each other, and a connection member 16 for connecting and fixing either one of the turbine impeller and the compressor impeller to an axial one end area of the shaft. The connection member 16 is subjected to plastic deformation so as to reduce the whole imbalance including the turbine impeller 11, the compressor impeller 12 and the shaft 13. |
