Abstract: This invention relates to an ignition distributor for an internal combustion engine and more specifically relates to a novel reluctor included in an ignition distributor for discriminating between cylinders of an engine. The reluctor has an elongated shape and is arranged relative to the rotating shaft of an ignition distributor so that the gravity center of the reluctor is located exactly on the rotational axis of the shaft. This arrangement enables the rotational movement of the shaft to be concentrated, so that the wear to which the bearings supporting the shaft is subjected is significantly reduced. The reluctor is attached to the governor base of an ignition distributor without any rivets by virtue of the novel configuration thereof, so that a reduction in the number of parts can be achieved, together with reduction in the total production cost.

Abstract: An ignition coil for an internal combustion engine can increase a contact area between an end of a GND line terminal and a bolt thereby to reduce the contact resistance therebetween. In the ignition coil, a GND potential is ensured by the GND line terminal that is electrically connected at one end thereof to an igniter and at the other end thereof to the internal combustion engine through a bolt inserted into a bolt insertion hole formed in a mounting flange. The GND line terminal is formed at the other end thereof with a bearing surface portion having a hole into which the bolt is inserted. At least part of an inner diameter of the hole in the bearing surface portion is smaller than an inner diameter of the bolt insertion hole.
