1. A rotor manufacturing apparatus configured to manufacture a rotor of a rotary electric machine, the rotor manufacturing apparatus comprising:
a resin injector having a first ejection port for ejecting a resin;
a runner having a charging port connectable to the first ejection port, and a plurality of second ejection ports communicating with the charging port and disposed at positions associated with hole portions of a rotor core where magnet members are disposed; and
a placement portion on which the rotor core is placed, wherein:
the runner is detachably attached to the placement portion,
the placement portion includes:
a support portion configured such that the runner is attachable to and detachable from the support portion, and configured to position and support the runner when the runner is attached;
a placement table disposed below the support portion, configured such that the rotor core is placeable on the placement table, and configured to ascend or descend relative to the support portion; and
a driving unit configured to drive the placement table to move, and
the resin injector is configured to inject the resin by causing the placement table on which the rotor core is placed to ascend so that the hole portions of the rotor core face the second ejection ports of the runner.
