Abstract:
A center surface portion (31) among a wall surface (30) radially inward of a cavity portion (21) is formed as recessed in relation to a rotation center (Q) of a rotor core (11). The center surface portion (31) includes a section near a first reference line (L1) that bisects an angle formed by two lines respectively connecting the two circumferential ends of the cavity portion (21) with the rotation center (Q) of the rotor core (11). A side surface portion (32) among the wall surface (30) radially inward of the cavity portion (21) extends from the center surface portion (31) to a circumferential end of the cavity portion (21). The side surface portion (32) is formed as projecting toward the intersection point (X) of the wall surface of a shaft hole (15) and a second reference line (L2) where the angle between the first reference line (L1) and said second reference line (L2) is an angle obtained by dividing 180° by the number of poles of the rotor core (11).
