Document Type and Number:

WIPO Patent Application WO/2014/034647

Kind Code:

A1

Abstract:

The present invention provides a grease composition for constant velocity joints, which contains: a lubricant base oil; at least one thickening agent that is selected from among urea thickening agents, urethane thickening agents and urea/urethane thickening agents; an organic molybdenum; zinc dithiophosphate; a polysulfide; and triglyceride. The content of the organic molybdenum is 1,000-5,000 ppm by mass in terms of molybdenum element based on the total mass of the grease composition. This grease composition is capable of exhibiting sufficient characteristics even in cases where the amount of an additive such as molybdenum disulfide is reduced.
