PURPOSE:To cope with the variation of specifications on the engine side simply and positively by forming a conductor connecting a heater bar and an external connecting terminal to a coil or corrugated shape and bringing the length in the axial direction to the irreducible minimum of a demand. CONSTITUTION:The conductor of a shape wound in a coil form is used as one 30 connecting the heater bar 11 and the external connecting terminal 14 in a holder 12, and the coil-shaped conductor 30 is incorporated into the holder 12 under the state in which it is inserted into a cylindrical insulating tube 31. Accordingly, flexibility sufficient to be able to absorb external force applied to the external connecting terminal 14 side is given, not only a buffer function is displayed but also length in the axial direction is brought to the irreducible minimum of a demand, and length in the axial direction of the glow plug 10 can be shortened in the coil-shaped conductor 30, and the conductor can cope with the modification, etc. of the specifications on the engine side. |
