Abstract

A rotor shaft (30) has a stopper portion (32) on a first end side, and has an outside threaded structure (44) on a second end side. A washer (70) is disposed between an end of a rotor core (20) on the second end side and an end of a nut portion (50) on the first end side. A position of a plane in which the washer (70) and the rotor core (20) are in contact with each other is located, in the rotor shaft (30), closer to the first end side in the axial direction than is the outside threaded structure (44) when the rotor core (20) is attached to the rotor shaft (30) by fastening the nut portion (50) to the outside threaded structure (44) of the rotor shaft (30).
