PROBLEM TO BE SOLVED: To provide a sliding surface structure which has high load capacity and can alleviate aggressiveness of a periodic structure part.SOLUTION: A sliding surface of a first member and a sliding surface of a second member slide relatively under a lubricant, in a sliding surface structure. On at least one sliding surface of either of the first member and the second member, an uneven periodic structure part in a grating shape and a periodic structure unformed part are alternately formed along a sliding direction. A fluid introduction groove is formed on an upstream side in the sliding direction of the periodic structure part. The periodic structure part is communicated with a peripheral edge of the sliding surface. A projection height position of the periodic structure part is set lower than a height position of the unformed part. |
