In addition, there is provided a discharge gas flowing-out member which is provided on the fixed scroll to cover an outlet side of the discharge port, forms a discharge space for the discharge gas, and forms a discharge gas flow passage for guiding the discharge gas discharged into the discharge space to an outer peripheral side. A ring-shaped discharge gas swiveling area is formed between an outer circumferential surface of the discharge gas flowing-out member and an inner wall surface of the hermetic container. The discharge gas flow passage in the discharge gas flowing-out member flows out the discharge gas into the discharge gas swiveling area to perform a swiveling motion. An upper part of the discharged gas swiveling area is provided with a baffle plate for guiding the discharge gas in this discharge gas swiveling area toward a central side of the hermetic container.SELECTED DRAWING: Figure 1
