Abstract
A rotor includes a shaft, a rotor core with core pieces arranged axially, and a plate between adjacent core pieces and surrounding the shaft. The shaft includes an axial first hole, and a second hole opened to outside of the shaft and connected to the first hole. One side of the plate in the axial direction has a first surface at an inner edge of the plate, and a second surface radially outward from the first surface. The first and second surfaces are away from the core piece, which is on the one side of the plate in the axial direction, toward the other side. The plate includes through-holes on the second surface and arranged circumferentially at intervals, and a plate wall protruding to one side in the axial direction from a portion of the first surface positioned radially outward from an inner edge.
