ABSTRACT:
In an insertion and engagement operation of a coil spring into the high tension terminal, the insertion end portion of the coil spring is inclined so that the projection portions may be located at upper and lower positions, and the outer diameter of the projection portions is approximately the same diameter as the outer diameter of the coil spring. The engagement portion of the high tension terminal includes an engagement hole, so that it can be visually confirmed that the insertion terminal portion of the coil spring has been engaged, the insertion end portion of the coil spring having been inclined in advance.
