In a scroll fluid machine, an orbiting scroll is revolved with respect to a fixed scroll in a housing. A self-rotation-preventing device is provided to prevent the orbiting scroll from rotating on its own axis. The device comprises a pair of holders, one of which is disposed in an orbiting side and the other is disposed in the housing. The holder in the orbiting side comprises a bearing, a holding plate for holding the bearing and a plurality of ears. At least one of the ears is disposed within a circle passing through the centers of the holders around the center of the orbiting scroll.
