Abstract
In a scroll fluid machine, a stationary scroll and an orbiting scroll are provided. On the stationary scroll opposing the orbiting scroll, an annular groove is formed. An O-ring, a flexible support ring and a sliding member are put in the annular groove. The support ring has legs between which the O-ring is held. The sliding member in sliding contact with the annular groove is placed on the support ring, thereby decreasing deterioration and keeping stable sealing.
