  • a phenylether lubricant consists of phenylether oil, and consequently the lubricant can be easily applied to the sliding portion of the mechanism that tends to become small-sized.
  • molybdenum disulfide is added to the phenylether oil, and consequently oil film thickness can be better retained, resulting in a further improvement of oxidation resistance as well as in a superior lubrication quality such as load resistance, persistence, etc.
  • molybdenum disulfides 1.0 to 5.0 wt% molybdenum disulfides are contained, and consequently improvement can be achieved both in the aspect of oil film thickness that is superior in oxidation resistance and in the aspect of dispersion stability of molybdenum.
