Abstract:
1. A sensor comprising a detecting element for detecting a state of a gas to be measured, and a metal shell that holds the detecting element, the metal shell including a fitting part for fitting the detecting element to an exhaust pipe when the detecting element is exposed to a gas to be measured, wherein an anti-seizing agent is present at an outer surface of the fitting part, said anti-seizing agent comprising: a first solid lubricant containing at least one of metallic bismuth and bismuth oxide; and a second solid lubricant containing at least one of graphite, molybdenum disulfide and boron nitride, a lubricant base oil; and a thickening agent selected from the group consisting of a calcium sulfonate complex soap, a lithium complex soap, a calcium complex soap, a lithium soap, a calcium soap, an organized bentonite, powdery silica, an aliphatic diurea compound, an alicyclic diurea compound, an aromatic diurea compound, a triurea compound and a tetraurea compound, wherein the anti-seizing agent satisfies 20 weight %≦a≦90 weight % and 10 weight %≦d≦80 weight %, in which a sum of the contents of the first solid lubricant and the second solid lubricant in the anti-seizing agent is taken as 100 weight %, and a represents the content of the first solid lubricant and d represents the content of the second solid lubricant, and when a sum of the contents of the first solid lubricant and the second solid lubricant is taken as 100 parts by weight, a sum b of the contents of lubricant base oil and the thickening agent satisfies 90 parts by weight≦b≦400 parts by weight.
