イーゼルエンジン用グロープラグ。 In a glow plug for a diesel engine, a rod-shaped ceramic heater having a resistor embedded therein is held in a hollow holder tip through a metal pipe fitted in the axial center of the rod-shaped ceramic heater. One end of the buried resistor is exposed at an outer peripheral portion closer to the rear end than the portion held by the metal pipe, and has a grip portion that grips the exposed portion at at least two positions in the circumferential direction. An electrode fitting formed by bending a thin metal plate is provided so that the proximal end connected to the gripping part via the arm is joined to the inner end of the metal pipe in a surface contact state. A glow plug for diesel engines with special features.
