Abstract
In a pair of sliding parts having sliding faces S that slide with respect to each other, at least one of the sliding faces S has a one-side peripheral edge (4a) and an other-side peripheral edge (4b) and includes: fluid introduction grooves (12) each of which has one end communicating with the other-side peripheral edge (4b), dynamic pressure generation grooves (11) each of which has one end communicating with the other-side peripheral edge (4b) and the other end being surrounded by a land portion, and a release groove (13) provided in the land portion, the release groove (13) communicating with the fluid introduction grooves (12). With the sliding parts, not only a liquid such as oil but also an oil mist serving as a mixture of oil and air can be sealed as a sealed fluid, and generation of oil mist itself can be reduced.
