A rotor capable of preventing a magnet or a cover tube from being damaged by contacting a mold of an injection machine during production. The rotor includes a rotor core, a plurality of magnets arranged on the outside of the rotor core in the radial direction, a cylindrical cover tube surrounding the plurality of magnets, and resin charged to a gap defined between an outer peripheral surface of the rotor core and an inner peripheral surface of the cover tube. An axial dimension of the rotor core is greater than an axial dimension of each magnet, and an axial dimension of the cover tube.
