<p>PURPOSE:To improve the reliability of mechanical strength and electric connection by placing a plug terminal metal in which the head terminal of an ignition plug is inserted between a casing and the bobbin of a secondary coil and pushing the inserted plug head inside the bobbin of the secondary coil. CONSTITUTION:A plug terminal metal 14 integrally has an inserted part 14a wherein the head terminal Pb of an ignition plug P is inserted, a cylinder 14b continuous to one end of the inserted part 14a and a terminal 14c projected from the outside of the cylinder 14b. The part 14a is inserted in the smaller diameter part 13c2 of the hole 13c for plug insertion of a bobbin 13 and the cylinder 14b is pushed in the larger diameter part 13c1. This prevents the slipping of the position or a damage by the vibration of an engine. Since an ignition coil Ig is connected to the ignition plug P in the state that the head terminal of the ignition plug is inserted in the inserted part 14a, the removal of the ignition coil from the ignition plug due to the vibration of the engine can be prevented.</p> |
