Abstract
An ignition unit promotes the efficiency of assembly because connections on the high voltage output side and the ground side are completed by a single operation, when an ignition electrode part and a main unit are connected together directly. A guide rail of the main unit is insertion-engaged into a slit between clamp pieces of a bracket so that the main unit is mounted onto the bracket. With the insertion engagement, a high voltage output terminal receives therein a high voltage input terminal of a spark plug supported by the bracket, a plate terminal which is a part of the bracket is driven into a ground-side connection terminal, and a convex portion of a projected piece is engaged into an engagement hole, for positioning and slipping-off prevention.
