PURPOSE:To improve the performance of preventing fretting wear occurring on sliding parts and joints of members used to restrain a relative motion by compounding a mineral oil type and/or synthetic lubricating base oil, a gelling agent and a specified compd. CONSTITUTION:A mineral oil type and/or synthetic base oil (A) with a viscosity (at 40 deg.C) of 10-200cSt, 2-25wt.% gelling agent (B) selected from urea compd. and (urea)urethane compd. consisting of a diurea compd. of the formula [wherein R1 is a 6-15C divalent arom. hydrocarbon group; R2-3 are each a cyclohexyl (a), a 7-12C cyclohexyl deriv. group (b), an 8-20C alkyl (c) or an alkenyl (d)] and being a mixture with a content of the components (a) and (b) of ((the number of the components (a)-(d)/the number of the components (a)-(d))X100) of 20-90% and contg. 10mol% or more compd. wherein R2 is the component (a)-(b) and R3 is the component (c)-(d) and 0.2-5.0wt.% compd. (C) selected from oxidized paraffin, diphenyl hydrogen phosphite and hexamethylphosphoric triamide are compounded. |
