PROBLEM TO BE SOLVED: To reduce the cost of a compressor, and to simplify maintenance work by improving separation efficiency of lubricating oil contained in a compressed refrigerant, improving reliability of the compressor, and using an integrally moldable member. SOLUTION: The compressed refrigerant delivered from a compression mechanism 15 flows in a first flow passage 72a to a peripheral direction of a sealed container. The lubricating oil contained in the compressed refrigerant is pushed to an outer peripheral direction of the sealed container 10 by centrifugal force, and sticks to an inner peripheral surface of the sealed container 10. Then, the lubricating oil falls downward the first flow passage 72a by the own weight, and is supplied to a narrow part wherein a width of a flow passage cross section in a radial direction of the sealed container 10 is narrow.
