Abstract
A rotor includes a shaft, a rotor core, at least one magnet, and at least one fixing portion. The shaft extends in an axial direction. The rotor core includes laminations, and at least one caulking portion. The laminations are stacked in the axial direction. The at least one caulking portion is located at a radial-directional inner side of the at least one magnet to caulk the laminations to each other. The at least one magnet is embedded in the rotor core. The at least one fixing portion fixes at least portions of outer peripheral edges of the laminations to each other.
