    Abstract: A glow plug having a main body bracket, a heater, a center shaft, an insulator, an O-ring that is provided between the front end surface of the insulator and the main body bracket, and a pin terminal that is fitted to the rear end portion of the center shaft and used for supplying electricity from the outside. The pin terminal includes a small-diameter portion, a flange, and a large-diameter portion where an engagement portion and a fitting recess are formed. The large-diameter portion includes a crimp formation region, which is formed so as to have the even outer diameter and be capable of being crimped, in a range from the front end thereof to the front end of the engagement portion. A part of the crimping target portion forms a crimping portion that fixes the rear end portion of the center shaft by crimping.

    Abstract: A sheath heater for a glow plug comprises a sheath tube having a closed front end portion, and an open rear end portion. An insulating powder is charged into a gap between the sheath tube and a heat-generating resistor disposed within the sheath tube. A seal member includes an expanded portion extending radially outwardly from an outer circumference of the seal member, and a non-expanded portion of a smaller outside diameter than the expanded portion and formed on the outer circumference of the seal member at least at a leading end of the seal member. The seal member is fitted into the open rear end portion of the sheath tube such that the leading end enters the sheath tube first. The sheath tube is deformed radially inwardly around the seal member for sealing the heat-generating resistor and the insulating powder contained in the sheath tube.

    Abstract: The invention relates to a spark plug and method for manufacturing it, which spark plug has been manufactured from one electrically conductive element and one electrically non-conductive element, sintered composite ceramic material having been used for the manufacture. These spark plugs can preferably be used for stationary-mode heaters, operated with fuels, of motor vehicles. According to the object which is set, it should be possible to manufacture such spark plugs cost-effectively and flexibly and at the same time provide an extended service life and oxidation resistance. The conductive element here is to be embraced on two opposite sides by the electrically non-conductive element and it has an enlarged cross section in the distal region while a cross-sectional ratio of between 2.5 and 5 to 1 is maintained with respect to the cross section of the electrically conductive element. The cross-sectionally tapered proximal heating region of the electrically conductive element is covered by 60 to 85% of its surface by the material of the electrically non-conductive element.
