Abstract
A rotor includes a rotor core, a first magnet, a second magnet, and a holder made of resin. Both a radially inner surface and a radially outer surface of the first magnet are covered with the rotor core. The second magnet includes a radially inner surface covered with the rotor core, and a radially outer surface exposed from the rotor core. The holder includes a first inner pressing portion and a second inner pressing portion. The first inner pressing portion presses the first magnet radially outward from a radially inner side of the first magnet. The second inner pressing portion presses the second magnet radially outward from a radially inner side of the second magnet. Accordingly, the first magnet and the second magnet are accurately positioned for the rotor core.
