{Technical Problem} Provide a sliding component that can prevent leakage while also providing lubrication regardless of the level of differential pressure between the inner periphery and outer periphery of the sealing face, by suctioning in the fluid in the cavitation area on the upstream side of the dimple or other concaved part formed on the sealing face and generating positive pressure between the sealing faces on the downstream side of the dimple. {Solution to Problem} The present invention is characterized in that dimples are provided on one sealing face of a pair of sliding parts that mutually slide relative to each other, where the cavitation formation area on the upstream side of each dimple is positioned closer to the low-pressure fluid side and the positive-pressure generation area on the downstream side is positioned closer to the high-pressure fluid side, and the fluid that has been suctioned in the cavitation formation area of each of the above dimples travels in the dimple and is returned to the high-pressure fluid side from the positive-pressure generation area. |
