Stage: PROBLEM TO BE SOLVED: To provide an excellent urea grease composition which hardly solidifies at a low temperature and can exhibit low and stable friction torque characteristics when sealed in a bearing or the like by combining a plurality of specific different urea compounds with a thickener.SOLUTION: One aspect of the present invention is an urea grease composition. The urea grease compound comprises: a base oil; and a thickener blended in the base oil and comprising an urea compound A and an urea compound B. The urea compound A is represented by a following general formula R1NHCONHR2NHCONHR3 (1) (in the formula, R1 and R3 independently represent an alkyl group having 6 to 10 carbon atoms, and R2 represents a divalent hydrocarbon group having 6 to 15 carbon atoms), the urea compound B is represented by a following general formula R4NHCONHR2NHCONHR5 (2) (in the formula, R4 and R5 independently represent an alkyl or alkenyl group having 12 to 20 carbon atoms), and a content of the urea compound B is 20 to 60 mass% based on a total mass of the thickener.SELECTED DRAWING: None (Grant)
