In a scroll-type fluid machine in which an eccentric drive pin protruding from a rotating shaft is slidably fitted into a slide groove bored in the drive bush, the orbiting scroll has a theoretical orbit radius. When in position, the gap between one end of the slide groove in the direction in which the turning radius increases and the eccentric drive pin is a preset minute distance δ (however, δ is the deformation due to processing error, temperature, and pressure of each scroll). etc.)
A scroll type fluid machine characterized by:
