Abstract
A scroll fluid machine comprises a fixed scroll, an orbiting scroll and a plurality of self-rotation preventing device for preventing the orbiting scroll from rotating on its own axis. On the rear surface of the orbiting scroll, a reinforcement bearing plate is fixed with a central bolt and an outer circumferential bolt. A follower of the self-rotation preventing device is provided in the reinforcement bearing plate. An oil-supply hole is formed through the reinforcement bearing plate to supply oil to the follower.
