    • A glow plug which includes an intermediate shaft (3) inserted into a shaft hole (43) of a metal shell (4) and having a connecting end part (36) of a rear end part (32) protruding from a rear end surface (48). An insulating member (6) is arranged between the intermediate shaft (3) and the shaft hole (43) of the metal shell (4). The insulting member (6) has a tapered part (63) which abuts a tapered part (47) provided in the metal shell (4). The insulating member (6) is pressed into position by a connecting terminal (5) fixed to the connecting end part (36) to assuredly hold the intermediate shaft (3) in a rear end part (45) of the metal shell (4) and to thereby prevent a deflection or bend of the intermediate shaft (3). Also disclosed is a method for manufacturing the glow plug.
    • 一种电热塞,其包括插入金属壳(4)的轴孔(43)中的中间轴(3),并具有从后端面(32)突出的后端部(32)的连接端部(36) 48)。 中间轴(3)和金属壳(4)的轴孔(43)之间设置有绝缘件(6)。 绝缘构件(6)具有抵靠设置在金属壳(4)中的锥形部分(47)的锥形部分(63)。 通过固定到连接端部(36)的连接端子(5)将绝缘构件(6)压入到位,以将中间轴(3)可靠地保持在金属壳(4)的后端部(45) 并由此防止中间轴(3)的偏转或弯曲。 还公开了用于制造电热塞的方法。
