Abstract
The present invention provides a grease composition for constant velocity joints containing a lubricating base oil, at least one thickener selected from urea-based thickeners, urethane-based thickeners and urea/urethane-based thickeners, an organomolybdenum, a zinc dithiophosphate, a polysulfide, and a triglyceride, wherein the content of the organomolybdenum is 1000-5000 ppm by mass in terms of molybdenum element based on the total amount of the grease composition. According to the grease composition, it is possible to exert sufficient characteristics even in the case of reducing the amount of the additive such as molybdenum disulfide.
