Abstract

A movable member slides on a fixed member. The movable member is made of aluminum alloy. An inner layer coats the movable member. The inner layer is made of a material capable of adhering to the aluminum alloy. An outer layer coats the inner layer and contacts the fixed member. The outer layer has greater hardness than the hardness of the inner coating layer.
