A rotor has a rotor core arranged to radially face a stator. The rotor core has an accommodation hole extending axially from an axial end face of the rotor core. A magnet is received in the accommodation hole. A recess, which is dented in a direction separating from the magnet, is formed in an end surface of the accommodation hole. The recess has an opening facing the magnet. A pair of open distal portions are arranged at opposite sides of the opening and pressed against the magnet.
