Low-friction sliding mechanism

A low-friction sliding mechanism, comprising:

• a first sliding member having a sliding surface, at least the sliding surface of the first sliding member being made of a diamond-like carbon material;
• a second sliding member having a sliding surface slidable relative to the sliding surface of the first sliding member, at least the sliding surface of the second sliding member being made of either one of an aluminum-based alloy material, a magnesium-based alloy material and a diamond-like carbon material;
• and
• a lubricant applied to the sliding surfaces of the first and second sliding members, the lubricant comprising at least one of an ashless fatty-ester friction modifier and an ashless aliphatic-amine friction modifier.
