摘要： Provided is a lubricating oil composition for a differential gear unit that is effective in limiting the generation of noise and vibrations even when a limited-slip differential is operated. The lubricating oil composition contains (A) a mineral oil and/or (B) a synthetic oil and (C) a friction modifier selected from amide- and imide-based friction modifiers and derivatives thereof in an amount of 0.01 to 10 percent by mass on the basis of the total mass of the composition. Also provided is a differential gear unit that is lubricated with the lubricating oil composition.

摘要： A sliding member includes a base material portion formed of steel; a nitrogen diffusion layer with a thickness of 10 μm to 50 μm; and a nitrogen compound layer with a thickness of 10 μm to 50 μm. The nitrogen compound layer and the nitrogen diffusion layer are formed by performing a first heating process of performing heat treatment on a material formed of steel in an ammonia atmosphere at a temperature of 570° C. to 660° C., a second heating process of performing heat treatment on the material in a non-oxidizing and non-ammonia atmosphere at a temperature of 660° C. to 690° C., the temperature in the second heating process being higher than the temperature in the first heating process, and an oil cooling process of performing oil cooling treatment at an oil temperature of 60° C. to 80° C. subsequently to the second heating process.

摘要： An annular wet clutch plate has lubrication grooves formed of multiple grooves in at least one of both axial end faces, the at least one of the both end faces having the lubrication grooves and a frictional engagement surface. The frictional engagement surface has a plurality of small grooves having a width and a depth that are smaller than those of the lubrication grooves. At least one of the small grooves is extended in a direction that crosses a circumferential direction of the annular clutch plate. A mean value of surface roughness of the frictional engagement surface having the small grooves is from 3.0 μm to 4.0 μm when the surface roughness is measured with the use of Rz at three positions that are offset from each other by 120° in the circumferential direction around a central axis of the annular clutch plate.
