Claims

[Scope of utility model registration request]

A bushing is rotatably fitted into a boss provided on an orbiting scroll that meshes with the fixed scroll, and an eccentric pin of a rotating shaft is rotatably fitted into an eccentric hole provided in this bushing, and the center of the rotating shaft is and a scroll-type fluid that causes the orbiting scroll to revolve around the center of the bush with a radius of revolution, and changes this radius of orbit in response to a moment around the center of the eccentric pin acting on the orbiting scroll. A scroll type fluid machine, characterized in that a spring is provided between the bush and the rotating shaft to bias the bush in a direction in which its center moves away from the center of the rotating shaft.
