Claims

[Scope of utility model registration request]

Consisting of a rotor with two or more pole pieces that are adjacent to each other and have different polarities, a U-shaped core placed around the rotor, and a power generation coil wound around the legs of the U-shaped core. A part of the pole piece that first faces the U-shaped core is extended in the rotational direction of the rotor, and the depth at which the rotor is buried is gradually deepened to construct a magnet generator. The machine includes a charging circuit that charges the positive voltage induced in the generator coil, a discharging circuit that discharges the charge of the charging circuit to the ignition coil, and a discharging circuit that discharges the discharge in the moe discharge circuit immediately before the positive voltage. An ignition control circuit that performs the ignition at a set level of negative direction voltage, and a retard control circuit that retards the discharge of the discharge circuit in the engine overspeed region by the discharge voltage of the charge and discharge circuit having a large discharge time constant. A non-contact ignition device for an internal combustion engine, characterized in that it is connected.
