Patent abstract
Sliding parts of a pair of annular bodies include sealing faces that relatively slide on each other. A reversed Rayleigh step mechanism serving as a negative pressure generation mechanism is provided in at least one of the sealing faces, and a negative pressure generation groove that forms the reversed Rayleigh step mechanism is provided in an arc shape along the circumferential direction of the sealing face so as to be isolated from a high pressure fluid side and a low pressure fluid side by a land section.
