ラミツクグロープラグ。 A ceramic heater is used in which a heating wire made of a high-melting point metal is embedded in a ceramic sintered body as a heating element provided at the tip of the mounting bracket, and a resistor is connected in series to the heating wire within the inner cavity of the mounting bracket. , the resistor coil is placed in a metal tube with both ends open, and within the tube, one end of the resistor coil is placed at the tip of a central shaft protruding from the rear end of the mounting bracket, and the other end is connected to the heating element. The resistor coil and the connecting portion are embedded in a heat-resistant insulating material filled in the inner cavity of the tube, and are formed as an integrated assembly. In a self-regulating ceramic glow plug having a structure in which a metal tube is caulked from the outer periphery with a part of the body of the mounting bracket and fixed in the inner cavity of the mounting bracket, the metal tube is separated from the buried part of the resistor coil. A self-controlling ceramic glow plug characterized by being fixed by caulking a part of the mounting bracket from the outer periphery of the upper center shaft buried part.
