Abstract:
An ignition coil for an internal combustion engine capable of effectively preventing leakage of noise occurring due to, for example, radio waves or unpleasant sounds generated by a spark discharge is provided. When an elastic O-ring  12,  which is a main part of the invention and which is made of a annular elastic resin material, is used as securing means, with a simple structure, it is possible to hold a second cap  9  (on a second electrode side) of an electric noise suppressing resistor  10  and to close a gap formed between an inner wall surface of a resistor accommodation section  4  and the second cap  9  of the electric noise suppressing resistor  10.  Therefore, this ignition coil is characterized in that, after securing the electric noise suppressing resistor  10  to the resistor accommodation section  4  by using the elastic O-ring  12,  even if the inside of the resistor accommodation section  4  is uniformly filled with the insulating material  5,  it is possible to prevent leakage to a location below the resistor accommodation section  4  from occurring.

Claim (Index 1):
An ignition coil for an internal combustion engine, the ignition coil causing a high voltage applied to a spark plug for the internal combustion engine to be generated, accommodated in a coil accommodation section, secured by injecting an insulating resin into the coil accommodation section, solidifying the insulating resin, and having an electric noise suppressing resistor that prevents leakage of noise occurring due to radio waves or unpleasant sounds that are generated by the ignition coil,\n the ignition coil comprising:\n a resistor accommodation section being a cylindrical space portion communicating with the coil accommodation section, being provided at a portion below the coil accommodation section when injecting the resin into the coil accommodation section, \n wherein a first electrode of the electric noise suppressing resistor is positioned at an upper side the resistor accommodation section being a side of the coil accommodation section, and a second electrode of the electric noise suppressing resistor is positioned at a lower side being a side opposite to the upper side, \n the resistor accommodation section including securing means, below the resistor accommodation section, for holding a side of the second electrode of the electric noise suppressing resistor and for closing a gap formed between an inner wall surface of the resistor accommodation section and the side of the second electrode of the electric noise suppressing resistor, and \n a securing means holding section for holding the securing means at a required position, having\n a plurality of upper protruding portions disposed at equal intervals in an inner peripheral direction of the resistor accommodation section, and \n a plurality of lower protruding portions provided below the upper protruding portions by a distance corresponding to a vertical width of the securing means and are disposed at equal intervals in the inner peripheral direction of the resistor accommodation section, and \n wherein the upper protruding portions and the lower protruding portions are alternately provided so as not to overlap each other in a circumferential direction as viewed from an axial direction of the resistor accommodation section being the cylindrical shape.
