Abstract:
This invention is concerning an ignition device for an internal combustion engine, wherein a plug boot has a reduced-inner-diameter portion having an inner diameter size smaller than that of the other portion, a spring has a larger diameter portion having a diameter size larger than that of the other portion, and a plurality of reduced clearances each having a width reduced by the reduced-inner-diameter portion and the larger diameter portion are formed between the spring and the inner wall surface of the plug boot.

Claim (Index 1):
An ignition device for an internal combustion engine, the ignition device comprising:\n an ignition coil having a primary coil, a secondary coil, an iron core magnetically coupling the primary coil and the secondary coil to each other, and an insulating case containing the primary coil, the secondary coil, and the iron core; a high-voltage tower provided integrally with the insulating case and internally holding a high-voltage output terminal which outputs, to the outside of the ignition coil, a high voltage generated in the secondary coil when conduction of an excitation current flowing in the primary coil is interrupted; a plug boot formed in a cylindrical shape and having an end portion attached to the high-voltage tower; and an interposing member provided in the plug boot and having a spring that is formed in a coil shape and electrically connects, to the high-voltage output terminal, an ignition plug terminal of an ignition plug having a tip portion facing an inside of a cylinder of the internal combustion engine, wherein the plug boot has a reduced-inner-diameter portion having an inner diameter size smaller than that of another portion, the spring has a larger diameter portion having a diameter size larger than that of another portion, and a plurality of reduced clearances each having a width reduced by the reduced-inner-diameter portion and the larger diameter portion are formed between the spring and an inner wall surface of the plug boot.
