The purpose of the present invention is to provide: a sliding mechanism having a lubricating film formed on the sliding surface thereof, and capable of exhibiting friction-reducing performance; and a friction reduction method for the same. To that end, the present invention entails coating the sliding surface with chromium nitride, adding a molybdenum dithiocarbamate with molybdenum in the amount of 600-1000 ppm to diesel engine oil, setting the arithmetic mean roughness of the sliding member to 2-60 nm, and upon converting the Sommerfeld number viscosity to Pa·s, the speed to s -1 , and the load to mean Hertzian stress (Pa), then the lubrication conditions for use are within the range of 2.12365x10 -20 to 5.94509×10 -19 . |
