PROBLEM TO BE SOLVED: To solve such problems that increase of thickness of a sealed container is required in a compressor using refrigerant such as CO<SB>2</SB>of which operation pressure is high in order to secure pressure resistance and a case part is the largest part in the sealed container, which increases the cost of materials and the weight. SOLUTION: A reinforcement cylindrical member attached to an outside diameter surface of a cylindrical part wherein deformation of the sealed container is easily generated by enlarging an inside diameter of a cylindrical part is attached to a suitable position where deformation is required to be prevented, and thereby, pressure resistance of the sealed container is improved.
