By using a lubricating oil composition capable of exhibiting excellent low friction properties while maintaining various characteristics as a lubricating oil, in combination with a sliding member having a specific DLC film on a sliding surface, To provide a sliding mechanism with excellent low friction properties. A sliding mechanism in which lubricating oil is interposed on a sliding surface on which two sliding members slide relative to each other, wherein the lubricating oil has a phosphorus-zinc-containing compound having a specific structure, and a specific structure. A lubricating oil composed of a lubricating oil composition comprising an additive selected from sulfur-containing compounds having a DLC film formed on at least one sliding surface of two sliding members; The DLC film is a sliding mechanism characterized by containing 1 to 30 atom% of tungsten (W) or molybdenum (Mo).
