<p><P>PROBLEM TO BE SOLVED: To provide a grease composition which uses together as a viscosity improver a thickener and a gelling agent, and moreover which is contrived to give a lower torque as well as to suppress a grease leakage by curtailing still more the content of the viscosity improver. <P>SOLUTION: The grease composition is a lubricant composition including a base oil and a viscosity improver of a mixture of a gelling agent and a thickener, wherein this grease composition is such that the gelling agent is an amino acid-based gelling agent or a benzylidene sorbitol derivative, and comprises a mixture having a ratio (a gelling agent:a thickener) of (50-95):(5-50), and besides contains 1-10 mass%, based on the whole amount, of a total of the gelling agent and the thickener. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
