Patent ID: 8206035

Claim:
A low-friction sliding mechanism wherein a low-friction agent composition is interposed between sliding surfaces of a DLC coated sliding member (A) and a sliding member (B), wherein the DLC coated sliding member (A) is formed by coating diamond-like carbon having a hydrogen content of 20 atomic percent or less on a base material; the sliding member (B) is formed of at least one kind of material selected from a group consisting of a metal material, a non-metal material and a coated material obtained by coating a thin film on a surface of the metal material or the non-metal material; and the low-friction agent composition contains an oxygen-containing organic compound (C), the oxygen-containing organic compound (C) being at least one kind selected from a group consisting of alcohols, esters, ethers, ketones, aldehydes, carbonates and derivatives thereof, wherein the oxygen-containing organic compound (C) is contained in the range of 0.05 to 3.0% mass relative to a total mass amount of the low-friction agent composition.
