Abstract: A rotor for a generator includes a core made of a plurality of magnetic plates laminated with each other, a magnet received in a holding portion of the core, and a synthetic resin mold molded on the core in the circular disc shape. A pawl is rotationally supported on the resin mold by means of a support shaft, and a stopper is formed on the support shaft or the resin mold. The stopper allows the pawl to engage the resin mold but prevents the pawl from disengaging from the resin mold. In case a conical opening is formed, a tapered punch may be pushed into a central opening of the core, so that a conical opening and thickened portion are formed on the core. The core can be directly connected to a crank shaft.

Abstract: In the rotor of a magneto generator, which has a magnet for generating electric power, the mechanical strength of the rotor is born by a metal core, and the metal core is connected to a resin molded disk by insert molding. The rotor is light and can bear the centrifugal force of high-speed revolution.
