Definitions

  • An ignition coil 12 is disposed above the spark plug 20.
  • the ignition coil 12 has an iron core 13 at the center thereof and is disposed vertically.
  • a rubber molding 15 embeds therein the ignition coil 12 so as to cooperate with the ignition coil 12 to constitute an integral unit.
  • the rubber molding 15 has a hollow lower end portion 15A in which the upper end portion 21A of the insulator 21 is fitted.
  • the hollow lower end portion 15A has at an inner periphery thereof a projection or smaller diameter section 15B.
  • the inner periphery of the lower end portion 15A serves as a second joining section joined with the above described first joining section, i.e., the outer periphery of the upper end portion 21A of the insulator 21.
  • the upper end portion 21A of the insulator 21 is fitted in the hollow lower end portion 15A of the rubber molding 15, while allowing the projection or smaller diameter inner peripheral section 15B of the rubber molding 15 to engage in the recess or smaller diameter outer peripheral section 21C of the insulator 21.
  • the ignition coil 12 and the spark plug 20 are firmly joined together.
  • the end of the connecting terminal 14 in the form of a needle is held assuredly in contact with the terminal 22, whereby it becomes possible to supply a high voltage produced by the ignition coil 21 to the spark plug 20 assuredly.
  • Fig. 2 shows a spark plug and ignition coil assembly according to the second embodiment of the present invention.
  • a hollow upper end portion of an insulator of a spark plug has an outer periphery serving as a first joining section, a hollow lower end portion of a rubber molding which embeds therein an ignition coil so as to cooperates with the ignition coil to constitute an integral unit has an inner periphery serving as a second joining section which is joined with the first joining section, and a fastening means is provided for fastening the first and second joining sections together, so the ignition coil and the spark plug are joined together with a large joining force so that leakage hardly occurs even if deterioration of the rubber molding occurs to sane extent.
