In a scroll compressor, the side of the orbiting end plate away from the compression chambers is slidably supported by an annular protusion formed in the frame. A lower pressure chamber is formed on the radially outer side of this annular protrusion, and an Oldham's ring is fitted inside the lower pressure chamber.
