Abstract: A rotor includes a rotary member, a plurality of permanent magnets disposed on an outer circumference of the rotary member, and a cover tube that is mounted to outer circumference of the permanent magnets to cover the permanent magnets, and is formed of a fiber reinforced plastic. At least one of the rotary member and the permanent magnets has a diameter enlarged portion having a diameter enlarged circumferential surface. The diameter enlarged portion has a diameter that enlarges from a first diameter region to a second diameter region. The first diameter region has a diameter equal to or less than an inner diameter of the cover tube. The second diameter region has a diameter equal to or more than an outer diameter of the permanent magnets.
