Abstract

Sliding parts are provided where a plurality of dynamic pressure-generating grooves for generating dynamic pressure via the relative rotational sliding of the stationary ring and the rotating ring are formed in a circumferential direction on a sealing face of one of a stationary ring and the rotating ring so as to communicate with a sealed fluid-containing space, and pumping areas for generating pumping action via the relative rotational sliding of the stationary ring and the rotating ring are formed within the dynamic pressure-generating grooves.
