Document Type and Number:
Japanese Patent JP7280800
Kind Code:
B2
Abstract:
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, whereinthe 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, anda penetration of the grease composition is 220 to 280.
