摘要： A rotor includes a rotor core comprised of magnetic steel sheets laminated in the axial direction and a pair of end plates that are respectively provided on the axial end faces of the rotor core so as to together sandwich the rotor core in the axial direction. The rotor is rotatably disposed in an electric rotating machine with a circumferential surface of the rotor core facing a stator. At least one of the end plates is configured to have through-holes, each of which is formed so as to axially penetrate the end plate, and a pressing portion that is radially positioned on the stator side of the through-holes. The pressing portion abuts a corresponding one of the axial end faces of the rotor core and exerts an axial load on the corresponding axial end face of the rotor core by an elastic force of the end plate.
