A grease composition which provides, in the working range of 150° C. to −40° C., an enhanced temperature control performance, a reduced low-temperature rotational torque and an improved boot resistance; and a constant velocity joint wherein the grease composition is filled; are provided. A grease composition for a constant velocity joint comprising the following components (A) to (E): n (A) a base oil containing 10 to 95% by mass of an ester synthetic oil produced from an aliphatic alcohol and an aromatic carboxylic acid and 90 to 5% by mass of a synthetic hydrocarbon oil; n (B) a thickener; n (C) molybdenum disulfide; n (D) molybdenum dialkyldithiocarbamate e; and n (E) zinc dithiophosphate. |
