Abstract
Provided is a sliding component capable of stably reducing the frictional resistance of a sliding surface entailing eccentric rotation. A sliding component has an annular shape with high-pressure and low-pressure fluids facing inside and outside of the sliding component and has a sliding surface relatively sliding with eccentric rotation. The sliding surface is provided with a plurality of high-pressure grooves open to a space in which the high-pressure fluid exists and a plurality of low-pressure grooves open to a space in which the low-pressure fluid exists. The high-pressure and low-pressure grooves are arranged in a circumferential direction.
