PROBLEM TO BE SOLVED: To provide a new grease composition for a constant velocity joint which shows an excellent effect in decreasing friction and abrasion even without use of molybdenum dialkyldithiocarbamate sulfide. SOLUTION: A grease composition comprising a basic oil and a urea-based viscosity increasing agent contains (A) 0.1 to 10 wt.% of an organic molybdenum complex, (B) 0.1 to 5 wt.% of at least one sulfur-containing additive selected from an olefin sulfide, a sulfur-phosphorous-based extreme pressure agent, a non-ash dithiocarbamate, a polysulfide, a thiodiazole-based compound and zinc thiocarbamate and (C) 0.1 to 5 wt.% of at least one additive selected from molybdenum dithiophosphate, zinc dithiophosphate and triphenylphosphorothionate. |
