Magneto-generator, method of manufacturing the same and resin molding die assembly for manufacturing the same

A resin molding die for manufacturing a magneto-generator which is comprised of a bowl-shaped flywheel, a plurality of magnets mounted on an inner peripheral surface of said flywheel, a resin filled around each of said individual magnets for fixedly securing said magnets to said flywheel as integral parts thereof, and a generator coil disposed within said bowl-shaped flywheel in opposition to said magnets for generating electric power under the action of electromagnetic induction brought about through cooperation with said magnets,

• said resin molding die comprising:
• an outer peripheral surface;
• said resin molding die being configured and arranged so that said outer peripheral surface can be positioned in opposition to an inner peripheral surface of said flywheel;
• and
• projections provided in said outer peripheral surface for holding said plurality of magnets at predetermined positions, respectively, wherein each of said projections extends continuously and axially from a given position at a side of said magnet.
