Document Type and Number:
WIPO Patent Application WO/2023/026755
Kind Code:
A1
Abstract:
Provided is a pair of sliding components which can suppress wear between sliding surfaces thereof from start of relative rotation to high-speed rotation and which can suppress leakage of a sealed fluid. A sliding surface 11 of a first sliding component 10 and a sliding surface 21 of a second sliding component 20 are configured to slide on each other with first positive pressure generating grooves 14, 15 and a second positive pressure generating groove 24 intersecting so as to overlap at least partially. The first positive pressure generating grooves 14, 15 include at least one groove 15 having a terminal end portion at a different position from that of another groove 14. The one groove 15 has a terminal end portion 15B located on a sealed fluid space S2 side with respect to a terminal end portion 14B of the other groove 14 and a terminal end portion 24B of the second positive pressure generating groove 24.
