摘要： The invention provides a grease composition for a speed reducer part of an on-vehicle electric component, the grease composition containing a base oil and a thickener, wherein
the base oil is poly-α-olefin or a mixed oil of poly-α-olefin and mineral oil having a kinematic viscosity of 4 to 19 mm2/s at 100° C. and a pour point of −30° C. or lower,
the thickener is a mixture of a diurea compound expressed by formula (1) and a diurea compound expressed by formula (2)
R1—NHCONH—R2—NHCONH—R1 (1)
R3—NHCONH—R2—NHCONH—R3 (2)
wherein R1 is a straight-chain alkyl group having 8 or 18 carbon atoms, R2 is a divalent aromatic hydrocarbon group having 6 to 15 carbon atoms, and R3 is an aryl group having 6 to 7 carbon atoms, and

摘要： In a vehicle having a microscopic dynamics friction mechanism formed of at least two parts and charged to a positive potential due to traveling, a lubricant in which first additive fine particles made of a resin that generates a negative potential are uniformly mixed with an electrically insulating base oil is disposed in a clearance between members of the friction mechanism. While the first additive fine particles are in frictional contact with the member, neutralization and elimination of the positive potential of the member are started. The first additive fine particles are attracted by a Coulomb force to the positive potential of the surface of the member other than a frictional contact part of the member when floating in the electrically insulating base oil and moving and circulating. The neutralization and elimination of the positive potential of the member are continued.
