A rotor core (11) comprises first ribs (61), each of which extends between a cavity of a cavity portion (21) and a cavity adjacent to said cavity in the circumferential direction from the radially inward side of the cavity portion (21) toward the radially outward side of the cavity portion (21). Each first rib (61) includes a linear portion provided as not overlapping with a first reference line (L1) that bisects an angle formed by two lines respectively connecting the two circumferential ends of the collective plurality of cavities of the cavity portion (21) with the rotation center (Q) of the rotor core (11), said linear portion extending from the radially inner side of the cavity portion (21) toward the radially outer side of the cavity portion (21) so as to follow the direction in which a force acts on the first rib (61) during rotation of the rotor core (11).
