摘要： A glow plug in which a convex portion (70) is formed in an outer peripheral surface (10b) of a heater (10) in a part facing an inner peripheral surface (137b) of a leading end part (137) of a housing (110) and interposed in a leading end side annular gap K1, so as to maintain a gap with the inner peripheral surface (137b). A decline in detection accuracy can be prevented to the extent that combustion gas can be received by the leading end (72) of the convex portion (70) even if soot clogging should occur.

摘要： A glow plug with a combustion pressure sensor is improved in airtightness between the same and a combustion chamber. The glow plug 100 includes a housing having a substantially tubular metallic shell extending in an axial direction and a substantially tubular cap member which is provided at the front end of the metallic shell, which is shorter in length along the axial direction than the metallic shell, and whose diameter decreases toward the front end thereof, a heater unit, a connecting member, and a pressure sensor. The cap member is formed of a material higher in tensile strength or yield strength than a material used to form the metallic shell, and the metallic shell is formed of a material higher in thermal expansion coefficient than that used to form the cap member.

摘要： A seal member (60) has a dual-tube structure consisting of an outer tubular seal member (160a) and an inner tubular seal member (160b); the outer tubular seal member (160a) is welded, at its rear end portion, to the inner circumferential surface of a forward-end housing (131), thereby forming a housing-side joint W2; the inner tubular seal member (160b) is welded, at its forward end portion, to a forward end portion of the outer tubular seal member (160a), thereby forming an inter-tubular-seal-member joint W3; and the inner tubular seal member (160b) is welded, at its portion located rearward of the joint W3, to the outer circumferential surface of the heater (10), thereby forming a heater-side joint W1. An action of pressing the heater forward is effected on the basis of an axial dimension L1 between the joints W2 and W1 shorter than an axial dimension between the joints W2 and W3 and is, therefore, mitigated.
