Abstract (en)

In a scroll fluid machine, an orbiting scroll comprises an orbiting end plate having an orbiting wrap and a fixed scroll comprises a fixed end plate having a fixed wrap. An engagement groove is formed at the tip ends of the orbiting wrap and fixed wrap, and/or the fixed or orbiting end plate. A seal is fitted in the engagement groove in sliding contact with a counter member. The seal comprises a sealing material and a backup material between the sealing material and the bottom of the engagement groove. The backup material has a plurality of projections which elastically stretch to press the inner circumferential surface of the engagement groove when the seal is pressed.
