PURPOSE:To prevent radiation of noise-wave and reduce the electrostatic capacity of a high voltage cord by applying a conductive cord cover which encloses the high- voltage cord into a bellows-shaped tube and connecting the said cord cover to the conductive cover installed onto ignition devices. CONSTITUTION:The first cord cover 90 made of soft conductive rubber is formed into the bellows-shaped tube having the mountain part 91 and the valley part 92 connected alternately. The cover 90 is installed onto the first high-voltage cord 41, and a space 95 is formed between the mountain part 90 and the outer periphery of the cord 40. Also the second cord cover 100 is formed basically likewise to the first cover 90 and installed onto the second high-voltage cord 50. A space 105 is formed between the mountain part 101 of the cover 100 and the outer periphery of the cord 50. The cover 90 is electrically connected with a coil cover 60 and a discover 70 and grounded, and the cover 100 is connected with the discover 70 and a plug cover 30 and grounded. Therefore, each high-voltage cord 40, 50 as the wave- noise radiation source is shiedlded, and the samll value of electrostatic capacity can be kept in each space 95, 105. |
