摘要： A lubricating grease composition comprising base oil and a blended thickener which comprises, as the thickener constituents, (a) one or more urea-type compounds; (b) one or more fatty acid metal salts; and (c) at least one type of amide compound selected from the group comprised of aliphatic amides and aliphatic bisamides shown by the general formulae (1) and (2) : R1CONH2 (1), R1CONHR2NHCOR1 (2), wherein R1 denotes a saturated or unsaturated alkyl group having from 15 to 17 carbon atoms and R2 denotes a methylene group or an ethylene group and wherein the blending weight proportions of (a) , (b) and (c) are in the ratio of a / (b + c) is in the range of from 0.20 to 10 wherein (1) constituent (a) has a blending weight ratio in the range of from 1 to 10; (2) constituent (b) has a blending weight ratio in the range of from 0.5 to 2.5; and (3) constituent (c) has a blending weight ratio in the range of from 0.5 to 2.5.
