    摘要： {Technical Problem} Provide a sliding component that reduces the leakage rate of sealed fluid and significantly improves the lubrication characteristics at startup or stop, while being actuated by means of fluid lubrication in the rotation phase, thereby achieving the effects of sealing and lubrication at the same time.
    {Solution to Problem} The sliding component is characterized in that: on one sealing face of a pair of sliding parts that slide relative to each other, multiple positive pressure-generating mechanisms that comprise extremely shallow parallel grooves running roughly in parallel with the sealing face and having submicron-level height differences are provided independently in the circumferential direction; the extremely shallow parallel grooves connect to the high-pressure fluid side, but are isolated from the low-pressure fluid side by a seal area; and extremely shallow thin grooves are formed at the bottom of the extremely shallow parallel grooves.

    摘要： There is provided a sliding component that supplies a sealed fluid to a leakage side in a gap between sliding surfaces to exhibit high lubricity and has a small leakage of the sealed fluid. A sliding component 10 that has an annular shape and is disposed in a place where relative rotation is performed in a rotary machine, includes a plurality of dynamic pressure generating mechanisms 14 provided in a sliding surface 11 of the sliding component 10, each of the dynamic pressure generating mechanisms 14 including a deep groove portion 15 that communicates with a leakage side, and a plurality of shallow groove portions 9A that communicate with the deep groove portion 15 and are arranged in a circumferential direction in parallel relationship to each other.
