A method of adjusting a thermal balance of a rotor. When obtaining a difference in shaftvibration component of the rotor between an actual load condition and a no load condition, on the basis of detection results at a simulated load, a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the outside and a difference in shaft-vibration component of the rotating rotor between a no-load condition and a condition in which the rotor is heated from the inside are detected at the simulated load. The detected differences in shaftvibration component are converted respectively to differences in shaft-vibration …
