ABSTRACT:
In a scroll fluid machine, an orbiting scroll is eccentrically revolved with respect to a fixed scroll by a driving shaft to compress a gas toward a center. To manufacture the orbiting scroll, a reference bore is formed at the center of orbiting scroll material, and a reference bore is formed at the center of bearing plate material. A dowel pin is inserted in the two reference bores. The orbiting scroll material is combined with the bearing plate material with a bolt and an adhesive.
