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.
