摘要： In a spark plug of the invention, as the top end edge of a terminal 13 is located within a middle trunk portion 2g of the insulator 2 with a longer reach of the screw portion 7, it acts as a support against fracture, more likely causing the problem of strength. Thus, the wall thickness of the middle trunk portion 2g at a position corresponding to the top end edge of the terminal 13 is sufficiently secured to be 0.42 or larger, based on the value of (Dnulld)/D, whereby it is possible to prevent the inconvenience such as fracture of the insulator, particularly, the middle trunk portion 2g from occurring owing to some strong force of bending, impact or torque applied on the insulator 2, when the spark plug is attached.
摘要翻译： 在本发明的火花塞中，由于端子13的顶端边缘位于绝缘体2的中间主体部分2g中，螺钉部分7的距离较长，所以它起支撑作用以抵抗断裂，更可能导致 力量的问题 因此，基于（Dd）/ D的值，在与端子13的顶端边缘对应的位置处的中间主干部2g的壁厚被充分地确保为0.42以上，由此可以防止 当安装火花塞时，由于施加在绝缘体2上的一些强大的弯曲力，冲击力或扭矩导致绝缘体断裂特别是中间主干部分2g的不便。

摘要： In insulator including alumina as a main component, a Na component in the insulator is set in the range of 0.07 to 0.5 wt % as Na2O. While the Na component content is as high as to have conventionally been regarded to be beyond the common sense, with this range of the Na component content, insulation resistance, mechanical strength and the like at high temperature are unexpectedly not reduced and an insulator with performances comparable to those of an insulator from conventional low soda alumina lower in Na component content than the above described range can be obtained. As a result, medium soda alumina and regular soda alumina that are much lower in cost than conventionally used low soda alumina can be used instead of the low soda alumina, so that dramatic reduction in production costs of insulator 2 for a spark plug 100 and in addition, of the spark plug 100 using the insulator 2 are realized.
摘要翻译： 在以氧化铝为主要成分的绝缘体中，绝缘体中的Na成分设定为Na 2 O 0.07〜0.5重量％的范围。 虽然Na成分含量一直高于以往被认为是超常常数，但Na组分含量的这一范围，高温下的绝缘电阻，机械强度等意外地没有降低，并且具有性能的绝缘体 可以得到与常规低苏打氧化铝相比，Na成分含量低于上述范围的绝缘体。 结果，可以使用比常规使用的低苏打氧化铝低得多的中等苏打氧化铝和规则的苏打氧化铝代替低苏打氧化铝，从而大大降低了用于火花塞100的绝缘体2的生产成本 此外，实现了使用绝缘体2的火花塞100。
