Patent ID: 6994474

Claim:
A rolling sliding member, comprising: an inside member having a raceway surface in an outer face; an outside member having a raceway surface opposite to the raceway surface of the inside member and disposed in the outside of the inside member; and rolling elements rollably placed between both raceway surfaces, wherein at least one of base materials of the raceway surface of the inside member, the raceway surface of the outside member and the rolling elements has a surface made of a steel, and a film is formed on the base material, wherein the film at least includes an intermediate layer having a metal component, a diamond-like carbon layer, an equivalent elastic modulus of 80 to 240 GPa, and a plastic deformation hardness of 8 to 37 GPa, wherein the plastic deformation hardness of the film is harder than that of a surface of the base material; wherein the film further comprises a composite layer, having a carbon component, between the intermediate layer and the carbon layer, and wherein a ratio of thickness of the composite layer divided by thickness of the film is in a range of 0.01 to 0.95.
