Abstract: A rotor manufacturing method for manufacturing a rotor including a rotor core, the rotor core having a permanent magnet mounted thereon throughout a circumferential direction, includes covering an outer circumference of the rotor core with a tubular rotor cover; and forming an angular portion conforming to an outer shape of the permanent magnet by pressing an open end of the rotor cover radially inward with use of a pressing member, the open end of the rotor cover axially projecting from an end of the rotor core before being pressed.
