Abstract
Abstract A starter dynamo having a pinion engageable with a ring gear and an armature for rotating the pinion is supplied at engine starting with an electric storage power from an electric double layered capacitor used exclusively for the starter dynamo. With this storage power, the armature rotates and, with this armature rotation, the pinion rotates. An engine ring gear is driven through the pinion to start the engine. After the engine starting, the ring gear rotation is transmitted to the armature through the pinion and the starter dynamo charges the electric double-layered capacitor. Thus, an electric storage power required for the next engine starting is charged in a short period of time.
