Low friction sliding mechanism

A low friction sliding mechanism employed in an internal combustion engine of an automotive vehicle. The low friction sliding mechanism includes first and second sliding members which are in slidable contact with each other. At least one of the first and second sliding members has a sliding surface portion whose at least a part is formed of a resinous material containing hydrophilic fine particle. Additionally, a lubricant exists between the first and second sliding members and includes a friction modifier containing at least one of organic oxygen-containing compound and aliphatic amine-based compound.
