ABSTRACT:
A magneto generator can provide a flywheel with a high circularity while reducing man hours in processing the flywheel. A bowl-shaped flywheel has a cylindrical portion and a bottom. A plurality of permanent magnets are arranged on an inner peripheral wall surface of the cylindrical portion. A magnet cover is arranged along inner surfaces of the magnets, bent into a cylindrical shape, and has its opposite ends bonded to each other by a diametrally extending joint portion. A resin material is arranged on an inner side of the flywheel to integrate the magnets and the magnet cover with the flywheel. The flywheel is formed, at the bottom side of the cylindrical portion, with a pair of concave and convex portions arranged in opposition to each other. The joint portion is sandwiched between the concave and convex portions whereby the circumferential positioning of the magnets with respect to the flywheel is performed.
