<p><P>PROBLEM TO BE SOLVED: To provide an internal combustion engine ignition coil that improves the assembly of each coil without deteriorating magnetic circuit performance. <P>SOLUTION: This internal combustion engine ignition coil comprises an iron core 21 composed of an outer ring iron core and a central iron core traversing the interior of the outer ring iron core and forming a closed magnetic circuit with the outer ring iron core. The central iron core 24 is separated from the outer ring iron core, the outer ring iron core is separated from a C-shaped part 22 and an I-shaped part 23 in a way that the end of the central iron core 24 is formed as an arcuate convex 24b to the I-shaped part 23, and the I-shaped part 23 corresponding to this convex 24b is formed as an arcuate concave 23b. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
