Abstract
A scroll fluid machine comprises a fixed-side member including a cylindrical casing and a fixed scroll fixed to the casing, and an orbiting scroll and a plurality of ball coupling devices provided between the fixed-side member and the orbiting scroll to prevent self-rotation of the orbiting scroll on its axis and receive a thrust load between the fixed-side member and the orbiting scroll. Each of the ball coupling devices comprises a first ball coupling mechanism for supporting the thrust load generated between the fixed-side member and the orbiting scroll and a second ball coupling mechanism disposed with a space from the first ball coupling mechanism to prevent the self-rotation of the orbiting scroll.
