A grease composition is described comprising 0.1 to 10 partsnby weight of a powdery molybdenum oxysulfide dithiocarbamatencomposition which comprises a compound represented by thenfollowing general formula (1):n nwherein R 1 , R 2 , R 3 and R 4 are independent hydrocarbyl groupsnand may be the same or different groups, and the total numbernof carbon atoms contained in R 1 to R 4 is 4 to 36; and whereinnX is sulfur or oxygen and the composition of the total of allnXs is given as S m O n in which n and m satisfy the ranges ofn1.7 ≤ m ≤ 3.5 and 0.5 ≤ n ≤ 2.3, respectively, and in whichnthe constituent particles have diameters of not larger thann50 µm, based on 100 parts by weight of a base grease. |
