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 combustion pressure sensor (1) includes a housing (2) having an axial hole (23), a flexible member (8) fixed at one end to the housing (2) and being displaceable along the direction of axis (CL1), a pressure transmission body (3) whose outer circumferential surface is fixed to the other end of the flexible member (8), and a sensor element (42) fixed to the housing (2) and outputting a signal on the basis of a pressure applied thereto from the pressure transmission body (3). The housing (2) includes a main body portion (21) having a screw portion (24), and a cap member (22) having a press contact portion (26) which is pressed against the internal combustion engine when the screw portion (24) is screwed into the mounting hole of an internal combustion engine. The one end of the flexible member (8) is fixed to the main body portion (21).

摘要： A protective sleeve for a spark plug includes a center electrode, an insulator, an attachment fitment having an attachment screw section formed on an outer peripheral surface thereof, and a ground electrode. A protective sleeve is disposed in a detachable manner on the outer periphery of the attachment screw section. The attachment fitment includes a flange section that has a diameter larger than that of the attachment screw section on a base end side of the attachment screw section. The protective sleeve includes a main body cylinder section having an inner diameter that is the diameter of the attachment screw section or larger, and smaller than the diameter of the flange section, a large diameter cylinder section having an inner diameter that is the diameter of the flange section or larger, and a step section formed between the large diameter cylinder section and the main body cylinder section.
