PROBLEM TO BE SOLVED: To provide the rotor of a dynamo-electric machine in which the bulge of an outer periphery side rotor core and an inner periphery side rotor core to the outer side can be suppressed.SOLUTION: A rib 70 includes an inner periphery side rib 80 having a first inner periphery side rib 82 and a second inner periphery side rib 84 extending, respectively, to one side in the circumferential direction and the other side in the circumferential direction, from an inner periphery side rotor core 25 toward an outer periphery side rotor core, and an inner periphery side connection 86 interconnecting the outer periphery side end of the first inner periphery side rib 82 and the outer periphery side end of the second inner periphery side rib 84, an outer periphery side rib 90 having a first outer periphery side rib 92 and a second outer periphery side rib 94 extending, respectively, to one side in the circumferential direction and the other side in the circumferential direction, from an outer periphery side rotor core 26 toward an inner periphery side rotor core 25, and an outer periphery side connection 96 interconnecting the inner periphery side end of the first outer periphery side rib 92 and the inner periphery side end of the second outer periphery side rib 94, and a connection rib 72 connecting the inner periphery side connection 86 and outer periphery side connection 96. |
