Abstract
In an embodiment, a sliding part is provided with a mechanism to generate dynamic pressure by means of relative sliding of a pair of sealing faces of the sliding part, which is characterized in that one sealing face is provided with a land 10 for generating dynamic pressure facing the high-pressure fluid side and a seal area 11 facing the low-pressure fluid side, wherein the land 10 and seal area 11 are positioned away from each other in the radial direction and the areas of the sealing face other than the land 10 and seal area 11 are formed lower than these areas to constitute fluid communication paths 12. The fluid entering the grooves for generating dynamic pressure formed on the sealing face is allowed to circulate.
