Abstract
There is provided a sliding component disposed at a relative rotational location of a rotating machine to slide relative to another sliding component. The sliding component has a sliding surface provided with a fluid inlet groove communicating with at least one of a sealed fluid side space and a leakage side space and a dynamic pressure generation groove communicating with the fluid inlet groove and extending in a circumferential direction. Both side edges and a terminating end edge of the dynamic pressure generation groove are curvedly continuous with each other in a plan view.

A sliding component which is disposed at a relative rotational location of a rotating machine to slide relative to another sliding component, the sliding component having a sliding surface provided with:
- a plurality of fluid inlet grooves each communicating with at least one of a sealed fluid side space and a leakage side space;
- and
- a plurality of dynamic pressure generation grooves each having one end which communicates with the fluid inlet groove and other end which is a closed end, and extending from the one end to the closed end in a circumferential direction,
- wherein both side edges and a closing end edge of each of the dynamic pressure generation grooves are curvedly continuous with each other in a plan view, and
- the closed end of one of adjacent two of the dynamic pressure generation grooves overlaps, in a view of the circumferential direction, with the fluid inlet groove communicating with remaining one of the adjacent two of the dynamic pressure generation grooves on a downstream side of relative rotation direction.
A sliding component which is disposed at a relative rotational location of a rotating machine to slide relative to another sliding component, the sliding component having a sliding surface provided with:
- a fluid inlet groove communicating with at least one of a sealed fluid side space and a leakage side space;
- and
- a dynamic pressure generation groove communicating with the fluid inlet groove and extending in a circumferential direction,
- wherein both side edges of the dynamic pressure generation groove are connected to each other by a closing end edge which is formed in a semi-elliptical shape in a plan view.
A sliding component which is disposed at a relative rotational location of a rotating machine to slide relative to another sliding component, the sliding component having a sliding surface provided with:
- a fluid inlet groove communicating with at least one of a sealed fluid side space and a leakage side space;
- and
- a dynamic pressure generation groove communicating with the fluid inlet groove and extending in a circumferential direction,
- wherein the dynamic pressure generation groove has a first side edge disposed on a leakage side in a plan view and a second side edge disposed on a sealed fluid side, and a closing end edge on a terminal end side,
- the first side edge and the closing end edge are connected to each other by a first arc in the plan view,
- the second side edge and the closing end edge are connected to each other by a second arc in the plan view.
A sliding component which is disposed at a relative rotational location of a rotating machine to slide relative to another sliding component, the sliding component having a sliding surface provided with:
- a fluid inlet groove communicating with at least one of a sealed fluid side space and a leakage side space;
