Abstract: In an ignition coil for an internal combustion engine, a resistor is disposed in a tower insertion hole of a high-voltage tower section. A coil spring is inserted in the tower insertion hole. An inner diameter of a proximal end side portion of the tower insertion hole is larger than an outer diameter of a maximum outer diameter portion of the resistor. An inner diameter of the distal end side portion of the tower insertion hole is larger than an outer diameter of a proximal end side portion of the coil spring, and is smaller than the outer diameter of the maximum outer diameter portion. In a state where the coil spring is pulled out from the tower insertion hole, the maximum outer diameter portion is restrained by the distal end side portion of the tower insertion hole, and a gap is formed between the resistor and a high-voltage cap.

Abstract: An ignition coil for an internal combustion engine is equipped with an assembly of a connector casing and a coil body. The coil body includes a primary winding wound around a primary spool. The connector casing has terminals each of which is equipped with a conductor fastener. The conductor fastener has a slit in which one of ends of the primary winding is fit to make an electric connection between the terminal and the primary winding. The primary spool has conductor guides and a backup support to establish alignment of each of the ends of the primary winding with one of the conductor fasteners and also to facilitate insertion of each of the ends of the primary winding into one of the conductor fasteners when the coil body is fitted into the connector casing, thereby ensuring the stability of electric connection between the primary winding and the terminal.

Abstract: An ignition coil for an internal combustion engine is provided.The ignition coil includes: a primary coil and a secondary coil magnetically coupled to each other; a second spool which the secondary coil is wound around; and a connection terminal connected to a high voltage side of the secondary coil and supported by a terminal support portion provided at the second spool. The terminal support portion includes an insertion hole portion allowing the connection terminal to be inserted in an insertion direction as a coil radial direction. The connection terminal includes a protrusion protruding outside the connection terminal in a direction orthogonally crossing the insertion direction. The protrusion is engaged to the insertion hole portion from inward in the coil radial direction.

Abstract: In an ignition coil for an internal combustion engine, a coil case includes a housing section and a high-voltage tower section. The housing section houses a primary coil, a secondary coil, a center core, and an outer peripheral core, and is arranged outside a plug hole in a cylinder of an internal combustion engine in which an ignition plug is arranged. The high-voltage tower section protrudes from the housing section, and is disposed within the plug hole. A pole joint is disposed within the plug hole, and is mounted to the high-voltage tower section via a seal rubber. The pole joint is provided with a rib that protrudes to an outer periphery and faces an inner peripheral surface of the plug hole. The inner peripheral side of the rib faces the high-voltage tower section via the seal rubber.
