ラグ。[Scope of Claim for Utility Model Registration] (1) A coiled heating resistance wire is embedded in a rod-shaped ceramic sintered body, a positive electrode extraction fitting is provided at the base end of the ceramic sintered body, and the temperature is raised rapidly when the engine is started, and then kept constant. This is a rapid heating-temperature saturation type glow plug designed to saturate the temperature, and the heating resistance wire at the tip of the ceramic sintered body is provided with a first dense portion where the coil winding pitch is dense. A first coarse part with a coarse coil winding pitch is provided from the dense part to the anode extraction metal fitting side, and first and second coarse parts with a larger coil winding pitch than the first coarse part are provided.
The second dense part is connected to the positive electrode extraction fitting through the second dense part sandwiched between the coarse parts, and the number of coil turns and length of the second dense part are smaller than that of the first dense part. A rapid temperature rise-temperature saturation type glow plug characterized by the fact that all the heat-generating resistance wires are made of a single wire made of the same material. (2) The rapid temperature rise according to claim 1 of the utility model registration claim, in which the second dense portion is arranged avoiding the metal tube that holds the ceramic sintered body and the metallized portion formed on the base end electrode portion. - Temperature saturated glow plug.
