摘要： A glow plug includes: a sheath tube (810) extending in the axial direction and whose forward end is closed; an axial rod (200) inserted into the sheath tube; a spiral forward coil (820) disposed in the sheath tube and connected to a forward-end inner wall surface of the sheath tube; and a spiral rear coil (830) disposed in the sheath tube and connected between a rear end portion of the forward coil and a forward end portion of the axial rod. A resistance ratio R1 and a resistance ratio R2 satisfy the relational expression R1 > R2, where the resistance ratio R1 is the ratio of the resistance of the forward coil at 1,000°C to the resistance of the forward coil at 20°C, and the resistance ratio R2 is the ratio of the resistance of the rear coil at 1,000°C to the resistance of the rear coil at 20°C. A main component of the forward coil is tungsten (W) or molybdenum (Mo) to restrain melting thereof when high-temperature control is performed.

摘要： The present invention prevents the occurrence of damage on a small diameter portion 4a which is formed on a rear end portion of a ceramic heater fixed in a metallic outer sleeve 8. The ceramic heater 4 is fixed in the metallic outer sleeve 8 by blazing or the like in a state that a heat generating portion formed on a distal end thereof is exposed to the outside. The rear end portion of the ceramic heater 4 is positioned inside the metallic outer sleeve 8, and the small diameter portion 4b is formed on the rear end. The rear-end small diameter portion 4b of the ceramic heater 4 is connected to an electrode lead-out member (electrode lead-out wire 10) for taking out a positive electrode of a heat generating material. Granulated powder (alumina, for example) 18 made of inorganic insulating material is filled in around a connecting portion of the ceramic heater 4 in the metallic outer tube 8 and the electrode lead-out-wire 10, and in addition, magnesia 20 is sealed outside the granulated powder. Thereafter, swaging is performed to bring the magnesia 20 into a highly dense state thus fixing the electrode lead-out wire 10 and an electrode lead-out rod 12 in the metallic outer sleeve 8.

摘要： The object is to prevent damage to and overheating of an electric wire for electric discharge/ignition of a burner, thereby increasing its life, without increase in cost. The burner includes a housing 1, an intake pipe 3 and a burner head 4. Gas in the housing 1 is supplied to the burner head 4 through the intake pipe 3. An electric wire 8 extends through the intake pipe 3 which connects a piezoelectric element 7 to a core wire 10 from which electric discharge is generated near burner ports 9 of the burner head 4 by the piezoelectric element 7. Since the wire 8 is not exposed to outside the intake pipe 3, the wire 8 is never caught and damaged by an external object. Since air-gas mixture which is kept at around the room temperature is flowing through the intake pipe 3, the wire 8 is less likely overheat during use of the burner. Thus, it is not necessary to provide the wire 8 with a shield plate for protecting the wire 8. This simplifies the manufacturing steps and thus reduces the manufacturing cost.

摘要： To provide a glow plug capable of restraining a temperature drop in the event of lowering applied voltage for saturating temperature, while ensuring durability and provision of higher heating-up temperature.
A rearward coil connected to the rear end of a forward coil containing W or Mo as a main component has a resistance ratio R1 lower than a resistance ratio R2 of the forward coil, where the resistance ratio R1 is the ratio of the resistance of the rearward coil at 1,000°C to the resistance of the rearward coil at 20°C, and the resistance ratio R2 is the ratio of the resistance of the forward coil at 1,000°C to the resistance of the forward coil at 20°C. A tube has a tube forward portion ranging from the forward end of the tube to a position around the axial center of the forward coil and a tube rearward portion ranging from a position around the rear end of the rearward coil to a position around the forward end of the rearward coil. The wall thickness A of the tube forward portion is 0.5 mm or more; the wall thickness B of the tube rearward portion is 0.3 mm or more; and the minimal wall thickness B1 of the tube rearward portion is smaller than the wall thickness A of the tube forward portion.

摘要： [Objective] To provide a glow plug having a combustion pressure sensor whose accuracy in sensing combustion pressure is improved through mitigation of an action that a tubular seal member (holding member) disposed between the outer circumferential surface of a heater and the inner circumferential surface of a portion of a housing located toward the forward end of the housing presses the heater forward as a result of its instantaneous thermal expansion which arises instantaneously, since it is thin-walled and thus instantaneously assumes high temperature. [Means for Solution] 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.
