WIPO Patent Application WO/2021/205554

Kind Code:

A1

Abstract:

[Problem] To provide a pair of sliding components that slide relative to each other on a sliding surface, with which high sealability and low sliding torque can be realized even if used over a broad range of rotation speeds and regardless of the direction of rotation. [Solution] A pair of sliding components that slide relative to each other on a sliding surface. At least one sliding surface S comprises a dimple group 14 in which a plurality of dimples 12 are arranged, each dimple having an opening with a long axis L and a short axis K that are orthogonal to each other. In the dimple group 14, the dimples 12 are arranged so as to form a curve having a curvature which differs from the curvature of the circumference of the sliding surface S.
