PURPOSE:To facilitate the mounting of a plurality of magnets by arranging the magnets contained in a magnet case on the inner periphery of a rotor body, bending a thin-walled portion of the outer peripheral edge of a rotor body and interposing the case between the thin-walled portion and the bottom of the rotor body. CONSTITUTION:A magnet 5 is contained in a magnet case 4 in which pole pieces 6 are respectively engaged fixedly with windows 4e, 4f. The case 4 is arranged on the inner peripheral surface of a rotor body 1. A thin-walled portion formed at the outer peripheral edge of the rotor body 1 is bent inside. The magnet 5 is interposed fixedly through the case 4 between the thin-walled portion and the bottom of the rotor body 1. |
