ABSTRACT:
A magneto-generator, a method of manufacturing the same and a resin molding die for manufacturing the same. In the magneto-generator, a guard ring is omitted with the performance of the magneto-generator being enhanced. The magneto-generator is manufactured by making use of a resin molding die (21) having an outer peripheral surface (21d) to be positioned in opposition to an inner peripheral surface of a flywheel (11) and projections (21a) provided in the outer peripheral surface (21d) for holding a plurality of magnets (12) at predetermined positions, respectively. The magnets (12) are positioned and held stationarily at predetermined positions by the aforementioned projections, respectively, and spaces defined between the resin molding die (21) and the inner peripheral surface of the flywheel (11) are filled with a resin. After hardening of the resin, the resin molding die (21) is detached from the flywheel (11).
