Claim 8:
9. A method for manufacturing the rotor according to claim 1, the method comprising:
preparing the magnet that includes the pair of shoulders;
preparing the rotor core that defines the housing hole configured to house the magnet:
positioning the magnet in the housing hole such that the pair of shoulders are arranged in the circumferential direction;
preparing a mold device that includes:
a cavity configured to mold a resin disposed in a housing gap between the magnet and the rotor core in the housing hole; and
a gate connected to the cavity;

attaching the rotor core that includes the magnet in the housing hole to the cavity such that the gate is in communication with an inner gap of the housing hole in an axial direction of the rotor core, the inner gap being a gap defined between the magnet and the inner core;
supplying a molten resin into the inner gap through the gate; and
removing the mold device from the rotor core after the molten resin is solidified.
