摘要：
The invention provides a grease composition for lubricating resins which contains a base oil, a diurea compound represented by formula (I) as a thickener: R1—NHCONH—R2—NHCONH—R3 (I) (wherein R2 represents a bivalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and R1 and R3 each independently represent a straight-chain or branched alkyl group having 8 to 22 carbon atoms), and a chained hydrocarbon polymer having a weight-average molecular weight of 20,000 to 300,000.
