PROBLEM TO BE SOLVED: To obtain a grease composition for constant velocity joints, low in a frictional coefficient, large in an effect on reducing induced thrusts and excellent in durability. SOLUTION: This grease composition for constant velocity joints comprises (a) a base oil, (b) a diurea-based thickening agent of the formula: R<1> NH-CO-NH- C6 H4 -p-CH2 -C6 H4 -p-NH-CO-NHR<2> (R<1> and R<2> are each a same or different 6 or 7C aryl group or cyclohexyl group), (c) a molybdenum sulfide dialkyldithiocarbamate, (d) molybdenum disulfide, (e) a zinc dithiophosphate compound, and (d) a phosphorus-free sulfur-based extreme-pressure additive. |
