ABSTRACT:
In a glow plug configured such that a metallic, tubular member having a heater fixedly provided therein is joined to a metallic shell, an external-thread portion is formed on the outer circumferential surface of the metallic shell so as to allow the glow plug to be screwed into a plug-mounting hole formed in an engine head. An annular protrusion is formed on the outer circumferential surface of the metallic, tubular member in such a manner as to protrude radially outward, to annularly extend in the circumferential direction, and to be located in the vicinity of a distal end of the metallic shell. A distally-facing end face of the annular protrusion abuts an annular seat face in the mounting hole, and the metallic, tubular member and the metallic shell are joined such that a distal end face of the metallic shell abuts a rearward-facing end face of the annular protrusion.
