Abstract
(EN) Provided is a sliding component capable of stably reducing frictional resistance of the sliding surface accompanied by eccentric rotation. A sliding component 7 has a sliding surface 7a that relatively slides in accordance with the eccentric rotation. The sliding surface 7a comprises a land 79 and a plurality of dynamic pressure generation mechanisms 70 arranged in the circumferential direction. Each of the dynamic pressure generation mechanisms 70 includes a shallow groove portion 71 and a deep groove portion 72. The shallow groove portion 71 surrounds the periphery of the deep groove portion 72 and communicates with the deep groove portion 72.
(FR) La présente invention concerne un élément coulissant qui peut réduire de manière stable la résistance de frottement de la surface coulissante accompagnée par une rotation excentrique. Un élément coulissant (7) présente une surface de glissement (7a) qui coulisse relativement conformément à la rotation excentrique. La surface de glissement (7a) comprend un méplat (79) et une pluralité de mécanismes de génération de pression dynamique (70) disposés dans la direction circonférentielle. Chacun des mécanismes de génération de pression dynamique (70) comprend une partie rainure peu profonde (71) et une partie rainure profonde (72). La partie rainure peu profonde (71) entoure la périphérie de la partie rainure profonde (72) et communique avec la partie rainure profonde (72).
