Abstract (en)

A grease composition containing a lubricant base oil, diurea compounds represented by the following general formulas (1) to (3), and an organic molybdenum compound; 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 organic molybdenum compound is contained by 0.1 to 20 mass% based on the total amount of the grease composition: <CHEM> <CHEM> <CHEM> where R<1> is a hydrocarbon group containing an aromatic ring, R<2> is a divalent hydrocarbon group, and R<3> is a hydrocarbon group containing an aliphatic ring; <DF NUM="(4)">5 ≤ W1 + W2 + W3 ≤ 30 </DF> <DF NUM="(5)">0.1 ≤ (W1 + 0.5 x W2)/(W1 + W2 + W3) ≤ 1.0 </DF> 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.
