PROBLEM TO BE SOLVED: To provide a turbine rotor blade improved in the strength by aligning the center line of the center of gravity of a blade effective part and the center line of the center of gravity of a wheel stud part on the same line. SOLUTION: In this turbine rotor blade, the center line C1 passing through the center of gravity of the blade effective part 12 coincides with the center line C2 passing through the center of gravity of the wheel stud part 13 of a wheel 1.
