Document Type and Number:
Japanese Patent JP7404351
Kind Code:
B2
Abstract:
Provided is a sliding component capable of obtaining high lubricity over the entire surface of a sliding surface. An annular sliding component 10 disposed at a relative rotation point of a rotating machine, includes a plurality of positive pressure generation grooves 15 are arranged side by side in a circumferential direction on a sliding surface 11 of the sliding component 10. The positive pressure generation grooves 15 are configured for generating positive pressure by a sealing target fluid F on the sealing target fluid side being introduced during the relative rotation of the sliding component 10 and a sliding component 20. The positive pressure generation grooves 15 have a plurality of leading edge portions 9a at leading edges on a downstream side in a direction of the relative rotation. The plurality of leading edge portions 9a are arranged side by side in the circumferential direction. At least part of the plurality of leading edge portions 9a is disposed at different radial positions.
