A scroll compressor includes a compression section having an orbiting scroll with volutes that are substantially symmetrically formed on both surfaces of an orbiting base plate. A main shaft penetrates through and is fixed to a center portion of the base plate. A pair of fixed scrolls is placed on both surfaces of the orbiting scroll, and has volutes which correspond to the respective volutes of the orbiting scroll to form compression chambers. The main shaft has a notch part which is formed at a portion penetrating through the orbiting scroll and fixed scrolls. A slider is provided which has an eccentric hole including a flat slide surface corresponding to the notch part. The slider is fitted to the main shaft where the notch part is formed. The slider is made slidable in a direction orthogonal to a length direction of the main shaft by the flat slide surface.

A scroll fluid machine that suppresses fluctuations in a port aperture area during each revolution of an orbiting scroll. Suction ports for sucking in a working fluid are disposed on a second base plate to have openings in a vicinity of a winding start end portion of a second spiral tooth, and near an inward facing surface of the second spiral tooth at a position separated by an involute angle approximately 90° from the winding start end portion of the second spiral tooth. Discharge ports for discharging the working fluid are disposed on a first base plate to have openings in a vicinity of a winding start end portion of a first spiral tooth, and near an inward facing surface of the first spiral tooth at a position separated by an involute angle approximately 90° from the winding start end portion of the first spiral tooth.
