Abstract
An end of each of slits of a rotor on a magnet insertion hole side has a triangular shape. A slit inner-side line of each of the slits includes an apex and a pair of side ends. An interval between each of the pair of side ends and the magnet insertion hole is larger than an interval between the apex and the magnet insertion hole, and an interval between the apex and the magnet insertion hole is larger than a plate thickness of each of steel plates forming a rotor core.
