Abstract
The rotor for an electric rotating machine includes a rotor core fixed to a rotating shaft and formed with at least one magnet accommodating hole, a magnet accommodated in the magnet accommodating hole, a resin portion filled in the magnet accommodating hole accommodating the magnet, a first end plate fixed to the rotating shaft at one axial side of the rotor core, and a second end plate fixed to the rotating shaft at the other axial side of the rotor core. The axial fixing force of the second end plate against the rotating shaft is smaller than that of the first end plate. At least a part of the resin portion is present in an axial area between the magnet accommodated in the magnet accommodating hole and the first end plate, and the magnet is in direct contact with the second end plate.
