Abstract: PROBLEM TO BE SOLVED: To provide a method for easily replacing a rotor blade of a rotor with an integral blade. SOLUTION: In a method for replacing a rotor blade 14 of a rotor 10 with an integral blade having a disk 12, the rotor blade 14 is detached in such a manner as to leave a blade stub portion 15 extending outward from the disk 12 and having a front edge, a rear edge, a suction part and a pressure part. Subsequently, a collar 24 having a hollow portion for receiving the blade stub portion 15 is prepared, and further, the blade stub portion 15 is contained inside the hollow portion of the collar 24, so that the collar 24 is connected to the blade stub portion 15. Consequently, a platform is formed of the blade stub portion 15 and the collar 24. Finally, another rotor blade to be replaced is connected to the platform.
