Abstract
A sliding machine includes: a pair of sliding members having sliding surfaces that oppose each other and are able to move relative to each other; and a lubricating oil which is able to be interposed between the opposed sliding surfaces, in which at least one of the sliding surfaces is covered with a chromium (Cr)-containing amorphous carbon film (chromium-coating DLC), and the lubricating oil contains an oil-soluble molybdenum compound having a chemical structure formed from a trinuclear material of molybdenum (Mo). Specifically, the chromium-coating DLC contains, when the entirety of the film is assumed to be 100 at. %, 1% to 49% of Cr, 0% to 30% of hydrogen (H), carbon (C) as a remainder, and impurities. The lubricating oil contains 5 ppm to 800 ppm of the oil-soluble molybdenum compound in terms of Mo mass ratio with respect to the entirety of the lubricating oil.
