Rotor

A rotor for a rotary electric machine, the rotor comprising:

• a shaft that includes a flange portion that protrudes to an outer radial side on one end in an axial direction;
• a rotor core that fits to the shaft in such a manner that rotational torque can be transmitted between the rotor core and the shaft;
• a first end plate that covers one end face of the rotor core in the axial direction;
• a second end plate that covers another end face of the rotor core in the axial direction,
• a nut member that is screwed to the shaft and that holds the rotor core with the flange portion in the axial direction;
• a first washer provided between the flange portion and the first end plate in the axial direction;
• and
• a second washer provided between the nut member and the second end plate in the axial direction, wherein
• the flange portion protrudes to the outer radial side from an outer peripheral surface of the shaft to which the rotor core is fitted, and
• the first washer is in contact with a seat surface of the flange portion in the axial direction, and has an outer diameter larger than an outer diameter of the seat surface of the flange portion.
