    摘要: A grease composition containing a lubricant base oil, diurea compounds represented by the following general formulas (1) to (3), and at least one species selected from the group consisting of paraffin oxides and phosphorus compounds; wherein respective contents of the diurea compounds represented by the following general formulas (1) to (3) satisfy conditions defined by the following expressions (4) and (5); and wherein the total content of the paraffin oxides and phosphorus compounds is 0.1 to 15 mass % based on the total amount of the grease composition: where R1 is a hydrocarbon group containing an aromatic ring, R2 is a divalent hydrocarbon group, and R3 is a hydrocarbon group containing an aliphatic ring; 5≦W1+W2+W3≦30  (4) 0.3≦(W1+0.5×W2)/(W1+W2+W3)≦0.7  (5) where W1, W2, and W3 are respective contents (mass %) of the diurea compounds represented by general formulas (1) to (3) based on the total amount of the grease composition.
