Abstract

PURPOSE:To effectively secure a magnet and to increase the magnetic flux density of the magnet by disposing ferrite magnets on the inner periphery of a cylindrical flywheel with a bottom, then inserting a thin magnet plate having elasticity into the inner peripheral side of the magnets and pressing and holding the magnets. CONSTITUTION:A projection 9 is formed on the inner peripheral base of a cylindrical flywheel 2 with a bottom, and a nonmagnetic annular holder 10 is disposed. An annular part 11 is formed at the opening end of the flywheel 2, the holder 10 is disposed, and circular-arc-shaped ferrite magnets 3 are interposed between two holders 10. A thin magnetic plate 12 having a bent projection 14 at one end is rounded and inserted into the inner peripheral side of the magnet 3, the projection 14 is fixedly engaged with the gap between the magnets 3, and the magnets 3 are fixedly pressed to the inner peripheral surface of the flywheel. In this manner, the magnets 3 can be secured without screw, and the electric power of the magnet generator can be increased.
