Abstract:
    A mold used in a manufacturing process of a rotor of an electric motor, the rotor including a rotor core with a plurality of magnet-retaining apertures and a plurality of permanent magnets individually received and retained in the magnet-retaining apertures of the rotor core, for pouring a resinous material into gaps defined between the respective magnet-retaining apertures and the respective permanent magnets. The mold includes a cavity for accommodating the rotor core at a predetermined position, with the rotor core receiving the plurality of permanent magnets individually in the plurality of magnet-retaining apertures; and an adjustable support mechanism for securely supporting the rotor core accommodated in the cavity in a manner as to meet a dimensional deviation in an axial direction of the rotor core.
