摘要：
A grounding member made of a spring steel includes a hexagonal top with a through hole, contact pieces extending from straight sides of the hexagonal top, and a grounding strip brazed to one of the contact pieces. The grounding member attaches to a spark plug with a spark plug insulator passing through the through-hole. The contact pieces pressure contact a peripheral surface of a hexagonal nut of the spark plug. A grounding wire is connected to a negative electrode of a battery. Electric charges generated in a spark gap are returned to the battery negative electrode from an external electrode of the spark plug via a spark plug housing, the grounding member, and the grounding wire. If the spark plug is loosely fitted in an engine cylinder head, or even if some engine body components are aged, electric charges flow without problems, preventing reduction of discharging performance.
摘要（中）：
由弹簧钢构成的接地构件包括具有通孔的六边形顶部，从六边形顶部的直边延伸的接触片和钎焊到接触片之一的接地片。 接地件附着在火花塞上，火花塞绝缘体穿过通孔。 接触件压力接触火花塞的六角形螺母的外周表面。 接地线连接到电池的负极。 在火花隙中产生的电荷经由火花塞壳体，接地部件和接地线从火花塞的外部电极返回到电池负极。 如果火花塞松动地安装在发动机气缸盖中，或者即使一些发动机主体部件老化，则电荷流动没有问题，防止排放性能的降低。
