    摘要： In an engine igniting coil device directly attachable to an igniting plug, both primary and secondary coil bobbins have flangeless ends, the secondary coil bobbin has inwardly protruding ribs for coaxially supporting the flangeless end of the primary coil bobbin mounted therein and the secondary coil bobbin also has a protrusion formed at its external wall apart from a high-voltage terminal of the secondary coil wound thereon and is coaxially mounted in a coil case by abutting its protrusion on an inner wall thereof, thus eliminating the possibility of damaging the bobbins by a large thermal stress produced in solidified insulating resin in a coil case by a differential thermal shrinkage in an axial direction and preventing a leakage current from a high-voltage side of the secondary coil bobbin to the coil case through a flange-like connection.

    摘要： In an engine igniting coil device which is embedded in a cylinder bore of an engine and directly connected with an igniting plug therein, a coil case containing an igniting coil assembly is made of conductive magnetic material and held at the ground potential level, thus preventing a decrease of output factor of the igniting coil device due to an iron loss of a produced magnetic flux when spreading about and passing a cylinder head of the engine and eliminating the possibility of leakage discharge from a high-voltage portion of the igniting coil assembly to the coil case and the cylinder head.
