PROBLEM TO BE SOLVED: To provide a rotor laminated iron core allowing permanent magnets inserted into the rotor laminated iron core to be respectively shifted to one of a surface on an inner peripheral side and a surface of an outer peripheral side of magnet insertion holes, and allowing the permanent magnets to be secured to the rotor laminated iron core without inclination of the permanent magnets.SOLUTION: Permanent magnets 12 respectively inserted into a plurality of magnet insertion holes 11 formed in a rotor laminated iron core are shifted to a surface of an outer peripheral side or a surface of an inner peripheral side of the magnet insertion holes 11, and are secured to the rotor laminated iron core with resin. A surface opposite to the surface to which the permanent magnets 12 in the magnet insertion holes 11 are configured to be shifted includes a resin sump part 13 and magnet holding parts formed at portions opposed to upper and lower end portions of the permanent magnets 12. |
