A sliding surface of at least one of sliding members sliding with respect to each other in a sliding direction comprises a protrusion extending along a direction intersecting the sliding direction and fine dimples provided on a surface of the protrusion. In the sliding members. lubricating oil is accumulated in the dimples, and is easily extracted through a drain portion formed by dimple in a running-in operation.

L'invention se rapporte à un élément coulissant dans lequel une partie fait saillie dans une direction coupant une direction de coulissement. Cet élément est disposé sur au moins une des surfaces de glissement des éléments coulissants qui coulissent les uns avec les autres, et de fines fossettes sont formées sur les surfaces de ladite partie en saillie. Ces fossettes servent à retenir l'huile et pendant la période de rodage, l'huile lubrifiante peut être plus facilement retirée d'une partie d'admission formée par lesdites fossettes.
