摘要： PROBLEM TO BE SOLVED: To provide an ignition device for an internal combustion engine, which has superior durability, such as heat-resistive impulse properties and insulating properties, and high reliability. SOLUTION: A center core 7, a low-pressure side core 18 or a high-pressure side core 9 is disposed inside a constituent member such as a primary bobbin 1, a secondary bobbin 3 or a case 5, or is housed in a pocket formed in the constituent member, or is covered with an elastic member, whereby the core is isolated from an insulating epoxy resin 6, and air is prevented from penetrating into a coil high-pressure part. Since no bubbles remain in the high-pressure part, and an internal crack caused by thermal shocks or the separation of the insulating epoxy resin 6 from the constituent member can be prevented, the heat-resistive impulse properties and insulating properties of a cylindrical ignition device can be enhanced.

摘要： PROBLEM TO BE SOLVED: To adapt an ignition coil device of an independent ignition type to an engine having plastic head covers by enhancing resistance to a thermal shock and the mitigation of an electric-field concentration between a secondary coil and a center core. SOLUTION: The ignition coil has a second coil 3 located inside a primary coil 5 while a soft epoxy 17 is filled between a secondary bobbin 2 and the center core 1. Since the soft epoxy 17 is injected from the low voltage side of the secondary coil, the secondary bobbin 2 is provided with a taper that causes such a difference in the inner diameter that the inner diameter of the secondary bobbin 2 is larger in the low voltage side of the secondary coil and is smaller in the high voltage side so that the thickness of the secondary bobbin is thinner in the low voltage side and is thicker in the high voltage side. The soft epoxy 17 has a recess 17' as a result of pressurized molding. The soft epoxy 17 has a glass transition point Tg (-40°C) that satisfies a condition that the allowable stress of the secondary bobbin is greater than stress generated at the glass transition point Tg (-40°C) of the insulating resin.
