ABSTRACT:
A construction for retaining an electrically conductive coiled spring which is inserted into a hollow of a high-voltage terminal subjected to a high voltage in an engine ignition system so as to electrically connect a head terminal of a spark plug or an ignition coil and the high-voltage terminal, the construction comprising: a first stopper which is formed on a side wall of the hollow of the high-voltage terminal so as to project into the hollow and is brought into contact with an insertion end of the coiled spring so as to retain the insertion end of the coiled spring; and a second stopper which is radially fitted around an outer surface of the side wall of the high-voltage terminal and is formed with a tongue piece and a projection; wherein the tongue piece is inserted between neighboring coil windings of the coiled spring in the hollow from a slit of the high-voltage terminal, while the projection is brought into engagement with a hole of the high-voltage terminal so as to be inserted between further neighboring coil windings of the coiled spring in the hollow.
