<p>PURPOSE:To realize a decrease in noise from radio, by installing through holes, which are formed to be insulated to metal tubes being housed in an armoring mold resin and composing a fixing hole for a car-body fixing hardware. CONSTITUTION:Metal tubes 16, to which a part of an ignition coil, that is, an armoring mold resin 17 is fixed with a car-body fixing hardware are housed in the armoring mold resin 17 which is molded by covering a high pressure terminal 12 and an external part of the coil 8 unitedly with thermoplastic syn thetic resin. Through holes 18 are formed to fix components such as the coil 8 in an iron mold when the armoring mold resin 17 is molded. The through holes 18 are insulated from the metal tubes 16, with them closed by inserting rubber bushes or the like into them, and therefore iron cores 13 and 14 are insulated to the car-body fixing hardware. Such composition, in which the igni tion coil for internal combustion engine insulates the iron cores to the car-body fixing hardware, realizes a decrease in noise in radio. And, closure by rubber can prevent water from invading the core part.</p> |
