PROBLEM TO BE SOLVED: To provide an oil level gauge for vehicle, including an O ring that can be produced by a simple method, by preventing the O ring of the oil level gauge from being fixed on an oil level gauge guide.SOLUTION: The oil level gauge for vehicle includes: a body of level gauge that is immersed in an oil sump in internal combustion of a vehicle and includes an oil surface detection part of measuring an oil level; and a handle part formed on the upper part of the body of level gauge. The body of level gauge includes an O ring of sealing oil by being inserted into an oil level gauge guide. The O ring is composed of a composition containing a fluororubber and a fluorine resin, and the fluorine resin is deposited on the surface of the O ring. The fluorine resin is a copolymer containing a polymerization unit based on ethylene and a polymerization unit based on tetrafluoroethylene. The fluororubber is a copolymer containing a polymerization unit based on vinylidene fluoride. |
