<p>PURPOSE: To prevent the backlash between a coil main body and iron cores with a simple shape by holding iron cores between two parallel parts by respectively press-contacting the parallel parts against the internal surface of an iron core inserting hole and the external surface of the coil main body. CONSTITUTION: A coil 2 is incorporated in a coil casing 1. The primary winding of the coil 2 is connected to a terminal in a connector section 1a and the secondary winding is connected to a terminal in a high-voltage terminal section 1b. One end sides of first and second iron coils 31 and 32 are inserted into an iron core inserting hole 4 into which a cylindrical iron core integrally provided on the bottom face 1f of the casing 1 is inserted. Then a closed magnetic path is formed by coupling the other end sides of the cores 31 and 32 with each other so that the coil 2 and core 3 can be interlinked with each other. The cores 31 and 32 are held between two parallel parts 3a and 3b installed to the iron cores 3 by respectively press-contacting the parts 3a and 3b against the internal surface of the iron core inserting hole 4 and the external surface of the coil casing 1.</p> |
