Abstract
A rotor for a rotating electric machine includes a rotor core, a plurality of permanent magnets, and a rotating shaft. The rotor core includes a through-hole, an inner circumference-side rotor core, an outer circumference-side rotor core, and a plurality of ribs. Each of the plurality of ribs includes a first curved rib and a second curved rib. The first curved rib extends to one side in a circumferential direction from an inner circumference side toward an outer circumference side. The first curved rib has a curved shape that bulges toward the outer circumference side and toward another side in the circumferential direction beyond a straight line that connects a first connecting portion between the first curved rib and the inner circumference-side rotor core and a second connecting portion between the first curved rib and the outer circumference-side rotor core.
