摘要： In an ignition device for an internal combustion engine, comprising a spark plug made to carry out an electric discharge between an center electrode and an earth electrode and an ignition coil having a primary winding and a secondary winding for supplying a high voltage to the spark plug, notch portions are made in a ceramic spool on which one of the primary and secondary windings is wound and projecting portion are made in an insulating-resin-made holding member into which connector terminals are incorporated, with the projecting portions being engaged with the notch portions. The engagement of the projecting portions and the notch portions prevents the connector terminals from moving with respect to the ceramic spool in circumferential directions of the ceramic spool during terminal connection work. This solves the problems in that, in the case of the employment of a ceramic spool, because difficulty is encountered in insert-molding the connector terminals in the ceramic spool, the connector terminals can move with respect to the ceramic spool during terminal connection work for the connection of the winding to the connector terminals to cause poor terminal connection workability.

摘要： In an ignition device for use in an internal combustion engine in which a spark plug and an ignition coil are integrated with each other and mounted in a cylinder head, a case is made of an electrical conductive material and one end portion of a secondary winding of the ignition coil is electrically connected to a center electrode of the spark plug while the other end portion of the secondary winding and an earth electrode of the spark plug are electrically connected to the case. Thus, the low-voltage side of the secondary winding and the earth electrode are electrically connected to each other through the case. This eliminates the need for a connector terminal and a wire harness for the electrical connection of the low-voltage side of the secondary winding to the internal combustion engine.

摘要： An insulator includes a coil side cylindrical portion extending from a plug side cylinder portion in a direction departing from a combustion chamber. One end of the coil side cylindrical portion protrudes in the direction departing from the combustion chamber with respect to a primary winding and a secondary winding. A pressure sensing element is disposed next to the one end of the coil side cylindrical portion. The signal lines of the pressure sensing element are taken out of a casing without passing aside an ignition coil. Thus, the diameter of the casing does not increase. The output signal of the pressure sensing element is not adversely influenced by discharge noises generated from the ignition coil.

摘要： An insulator includes a plug side cylindrical portion having an inner space for accommodating a center electrode and a coil side cylindrical portion extending in a direction departing from a combustion chamber. The high-voltage portion of an ignition coil is entirely accommodated inside the coil side cylindrical portion. According to this arrangement, the coil side cylindrical portion can assure insulation between the high-voltage portion and the low-voltage portion. The portion to be insulated and fixed by an insulating resin is limited only to the secondary winding.

摘要： A stator which may be employed in an electric rotating machine. The stator includes a stator winding which includes in-slot portions disposed in slots of a stator core. The in-slot portions are arrayed in each of the slots in a form of multiple layers aligned in a radial direction of the stator core. The stator winding is made up of a first winding and a second winding which are connected together through a joint. The first winding is defined by a portion of the stator winding between the joint and an end of the stator winding which is to be connected to an external. The second winding includes the in-slot portion placed within at least one of the slots as an outermost layer that is one of the layers placed most outwardly in the radial direction of the stator core. This results in a great decrease in leakage current.
