Zusammenfassung:A rotor structure of an outer-rotor type permanent magnet motor is provided to improve performance of a motor and to reduce vibration and noise of the motor by simplifying an assembling process of permanent magnets. A rotor structure of an outer-rotor type permanent magnet motor includes a herb(21), a plurality of pawl guides(22), and a plurality of permanent magnets(23). The herb is installed at an outer circumference of the stator. The pawl guides are installed in a constant interval in a circumferential direction and a width direction of an inner circumference of the herb. Each of the permanent magnets is installed at each of the pawl guides. The permanent magnets are installed at the plate. The pawl guide and the adjacent pawl guide are installed cornerwise to each other.
