PROBLEM TO BE SOLVED: To provide a grease composition to be used in stationary-type constant velocity joints, excellent in antiflaking performance and durability as well. SOLUTION: This grease composition for constant velocity joints comprises (a) a base oil, (b) a diurea-based thickening agent of general formula (I): R1-NH- CO-NH-C6H4-p-CH2-C6H4-p-NH-CO-NHR2 (wherein, R1 and R2 are each a 6C or 7C aryl or cyclohexyl), (c) molybdenum dithiocarbamate, (d) molybdenum disulfide, (e) a phosphorus-free sulfur-based extreme-pressure agent, and (f) sodium sulfonate. |
