1. A rotor comprising a rotor core arranged to radially face a stator, the rotor core having an accommodation hole extending axially from an axial end face of the rotor core, a magnet being received in the accommodation hole, wherein a recess dented in a direction extending away from the magnet is formed in a wall surface of the accommodation hole at an axial end of the accommodation hole, the recess configured to receive a staking jig, and having an opening that faces the magnet, the opening defined by a pair of opposing circumferential end walls forming a pair of open distal portions,
each of the open distal portions is plastically deformed to be pressed against the magnet, the plastic deformation of the open distal portions caused by insertion of the staking jig into the recess, and a staking mark is formed in the radially middle portion of the recess as a result of the pressing of the staking jig against the circumferential opposing end walls in an axial direction, and the staking mark intersects the recess as viewed axially, extending beyond a circumferential width of the recess. |
