Abstract
Provided is a sliding component capable of stably reducing the frictional resistance of a sliding surface entailing eccentric rotation. A sliding component has a sliding surface relatively sliding with eccentric rotation, in which the sliding surface includes a land and a plurality of dynamic pressure generation mechanisms arranged in a circumferential direction, the dynamic pressure generation mechanism includes a shallow groove portion and a deep groove portion, and the shallow groove portion surrounds a circumference of the deep groove portion and communicates with the deep groove portion.
