ABSTRACT:
A housing structure of an ignition coil assembly for an internal combustion engine is disclosed, in which the coil assembly and the igniter are accommodated in a single casing. The coil assembly is wound around a leg of a rectangular core having a yoke portion running parallel to it. The casing accommodates the coil assembly and the leg of the core carrying it, leaving exposed to the outside the yoke of the core; a space is formed between a side of the coil assembly and a side wall of the casing. A plate-shaped heat sink abutting on the yoke of the core at its lower end extneds witin the casing between the coil assembly and the casing through said space, forming within the space a hollow receptacle between opposing surfaces of the coil assembly and the casing. The igniter is mounted to the heat sink within the hollow receptacle. The housing structure is attached to the body of an automobile, etc., at a surface of the heat sink abutting on the yoke of the core.
