A grease composition which contains a large amount of thickener, and may prevent a flaking effectively for a long period of time, and machine elements in which the grease composition is filled are provided. A grease composition comprising a thickener and a base oil, characterized in that the thickener contains a diurea compound represented by the Formula (I):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒR 1 -NHCONH-R 2 -NHCONH-R 3 ,€ƒ€ƒ€ƒ€ƒ€ƒ(I)
wherein R 1 and R 3 are a phenyl group and/or a cyclohexyl group, R 2 is a C 6 -C 15 divalent hydrocarbon group, and the molar ratio of cyclohexyl group/(cyclohexyl group + phenyl group) in R 1 and R 3 is 0.95 to 0.10. |
