Abstract: The purpose of the present invention is to provide a scroll fluid machine, the reliability of which is ensured and which can be manufactured with high productivity. The present invention provides a scroll fluid machine comprising: a stationary scroll having a spiral wrap upstanding therefrom; an orbiting scroll provided facing the stationary scroll and orbiting; a casing provided outside the orbiting scroll; a drive shaft for causing the orbiting scroll to orbit; an orbiting bearing for transmitting the rotational movement of the drive shaft to the orbiting scroll; and a plurality of rotation prevention mechanisms for preventing the orbiting scroll from rotating. The scroll fluid machine is characterized in that: the rotation prevention mechanisms have crankshafts and also have crank bearings for supporting the crankshafts; and the gap between each of the crankshafts and the corresponding one of the crank bearings is set to be greater than the gap between the drive shaft and the orbiting bearing.
