摘要：
A positive pressure generation mechanism includes a positive pressure generation groove provided on a high pressure side of one of sealing faces of a pair of sliding parts including annular bodies that relatively slide on each other, a negative pressure generation mechanism including a negative pressure generation groove provided on a low pressure side, a pressure release groove provided between the positive pressure generation groove and the negative pressure generation groove, and a radial groove that provides communication between the positive pressure generation groove.
