Abstract
To allow necessary movement of a magnet in a magnet insertion hole during a manufacturing process so that a magnet embedded core in which the magnet is positioned as designed can be manufactured efficiently, a lower plate () and an upper plate () configured to contact against the end surfaces of a rotor core () are provided with pin members () configured to enter a magnet insertion hole () to allow movement of a magnet () in a first direction, which is a separation direction of two mutually opposing inner surfaces (C,D) of a magnet insertion hole (), and to restrict movement of the magnet in a second direction orthogonal to the first direction as viewed in the axial direction of the magnet insertion hole (), in a state where the magnet insertion hole is not filled with resin.
