PROBLEM TO BE SOLVED: To achieve a rotor for dynamo-electric machine in which the rotor core can be cooled appropriately over a wide region in the axial direction, even in a state where the rotor shaft is arranged while inclining for the horizontal plane or in a state where acceleration acts for the rotor shaft. ! SOLUTION: A rotor core 2 includes an axial oil path 30, a radial oil path 40 interconnecting an axial insertion hole 20 and the axial oil path 30, and a distribution regulation part 50 provided in an intermediate region of the axial oil path 30 in the axial direction L. The distribution regulation part 50 is configured to regulate distribution of oil between a first oil path part 31 arranged on the axial first direction L1 of the distribution regulation part 50 and a second oil path part 32 arranged on the axial second direction L2 of the distribution regulation part 50, at least in the rotational state of the rotor core 10. The radial oil path 40 includes a first interconnection 41 interconnecti |
