Lubricant composition
A lubricant composition includes a perfluoropolyether as a base oil, a fluororesin as a thickener, and a polyol ester, a urea grease and a zinc dialkyldithiophosphate as additives, wherein a mass ratio of content of the perfluoropolyether to total content of the polyol ester and the urea grease rang...
