[Technical Problem] An object is to provide a lubricant capable of forming a stable adsorption film on a sliding surface and stabilizing the sliding characteristics (for example, ensuring the wear resistance, etc.). [Solution to Problem] The present invention provides a lubricant represented by the following chemical structural formula. (R: a hydrocarbon group whose carbon number is 8 to 24, m and n: integers of 2 to 8) [Selected Figure] FIG.A

Lubricant, lubricating composition, and sliding machine

An oil deterioration suppressing apparatus is provided. The apparatus may include a filtering portion including a filter element for filtering oil, and a deterioration suppressing portion including a powdery deterioration retarder which suppresses deterioration of oil. The deterioration suppressing portion may include a flow passage wall which holds the powdery deterioration retarder and defines an oil flow passage, and the powdery deterioration retarder includes mesoporous inorganic material.

A low-friction sliding member is used under a wet condition employing a lubricant, and includes a substrate having a surface, and an amorphous hard carbon film formed on the surface of the substrate for contacting slidably with a mating member. The amorphous hard carbon film includes silicon in an amount of from 1 atomic % or more to 20 atomic % or less, hydrogen in an amount of from 20 atomic % or more to 50 atomic % or less, and the balance of carbon and inevitable impurities, when the entirety is taken as 100 atomic %, and exhibits a surface roughness Rzof 0.8 &#x3bc;m or less. The low-friction sliding member exhibits reduced friction coefficients between itself and mating members, without relying on the adsorption and reaction of additives, included in lubricants, to the amorphous hard carbon films.
