To provide a method of magnetizing and inspecting a rotor for magneto generators in which magnetization and magnetization inspection can be performed on one device, and the need of rotating the rotor is dispensed with when the propriety of magnetization or the angular position of the rotor (for example, the position of an ignition timing inspecting projection) are inspected, so that size reduction of the device can be effected, as well as reduction in the setting space and the installation costs of the device. A method of magnetizing and inspecting a rotor for magneto generators with a permanent magnet material fixed thereto, comprising steps of (a) mounting the rotor on a lifting shaft moving linearly; (b) detecting the angular mounting position of the rotor mounted on the lifting shaft during raising and lowering of the rotor; (c) linearly moving the rotor to a magnetizing position facing a magnetizing coil to magnetize the permanent magnet material when the angular mounting position of the rotor is determined to be appropriate at said step (b); (d) performing magnetization inspection when the rotor is linearly moved to cause said permanent magnet material to be away from said magnetizing coil after magnetization; and (e) dismounting the rotor from the lifting shaft.
