摘要：
A grease composition comprising a lubricating base oil, at least one diurea compound represented by one of the general formulas (1) to (3) below, a naphthenic acid salt, and succinic acid or a derivative thereof, wherein each of the proportions of the diurea compounds represented by general formulas (1) to (3) satisfies the conditions represented by inequalities (4) and (5) below, and each of the proportions of the naphthenic acid salt and the succinic acid or its derivative is 0.1-10 % by mass based on the total amount of the grease composition. Äwherein R represents a C7-12 aromatic ring-containing hydrocarbon group, R represents a C6-15 divalent hydrocarbon group, and R represents a cyclohexyl group or a C7-12 alkylcyclohexyl groupÜ 5 ≤ W1 + W2 + W3 ≤ 35 0 ≤ (W1 + 0.5 x W2)/(W1 + W2 + W3) ≤ 0.55 Äwherein W1, W2 and W3 represent the proportions of diurea compounds represented by general formulas (1) to (3), respectively, based on the total amount of the grease composition (% by mass)Ü.
