摘要： An ignition coil includes a coil body transversely arranged outside of a plug hole, and a plug connection portion protruding in a direction perpendicular to an axial direction of the coil body. A secondary coil of the coil body has a maximum outer diameter portion, and an inclined outer diameter portion arranged on two sides of the maximum outer diameter portion in the axial direction. The secondary coil includes a secondary electric wire that is wound obliquely around an outer periphery of a secondary spool such that reduced winding parts and enlarged winding parts are alternately superimposed on each other. The reduced winding part is wound with a winding diameter decreasing obliquely from one side to the other side in the axial direction, and the enlarged winding part is wound with a winding diameter increasing obliquely from the other side to the one side in the axial direction.

摘要： An ignition coil includes a housing which contains a central core portion, an inner spool having a first winding, and an outer spool having a second winding. The inner spool extends outward of the central core portion. The outer spool extends outward of the inner spool. A locating member includes a locating rib adjacent to an upper portion of the central core portion. The locating rib is in a gap between the inner spool and the central core portion, and locates the inner spool and the central core portion relative to each other. Insulating resin injected into the housing provides insulation among parts in the housing. At least one of the inner spool and the locating member has a void-escape passage which connects the gap and an outside of the inner spool with each other, and which allows a void to escape from the injected insulating resin in the gap.

摘要： In a stick coil, there is disclosed an ignition coil for an internal combustion engine which can prevent a crack (a collar leak) from being generated due to a thermal stress. In this ignition coil, the structure is made such that a size (L) of a portion which is in parallel to an axial direction of a primary spool (121) in a projection portion (121b) is larger than a size (T) of a portion which is in parallel to an orthogonal direction to the axial direction of the primary spool (121). Accordingly, a frontal projected area of the projection portion (121b) as seen from a flowing direction of a resin becomes small, a resin flow is hard to get out of order at a time when the resin flows through a portion corresponding to the projection portion (121b) at the forming time, and a convoluted void and a weld are hard to be generated. Accordingly, since it is possible to prevent a mechanical strength in a root portion of the projection portion (121b) from being reduced, it is possible to previously prevent a crack from being generated in the root portion of the projection portion (the collar portion) (121b) due to a thermal stress so as to reduce an insulating property.
摘要翻译： 在棒状线圈中，公开了一种用于内燃机的点火线圈，其可以防止由于热应力而产生裂纹（轴环泄漏）。 在该点火线圈中，该结构被制成使得与突起部分（121b）中的初级线轴（121）的轴向方向平行的部分的尺寸（L）大于 与主卷轴（121）的轴向的正交方向平行的部分。 因此，从树脂的流动方向看，突出部分（121b）的正面投影面积变小，在树脂流过与突起部分相对应的部分时，树脂流动难以变得不顺利 （121b），并且难以产生卷积的空隙和焊缝。 因此，由于可以防止突起部（121b）的根部的机械强度降低，所以能够防止在突起部（轴环部）的根部产生裂纹， （121b）由于热应力而降低绝缘性能。
