As described in the above publication, a frame body, an electric motor section and a compressor section attached to the frame body are housed in a closed container, and these two rock sections are connected by a rotating shaft. It is constructed by closing the opening of the cylinder of the compressor section with a valve plate and cylinder head. Here, since the closed container is a pressure container to which an internal pressure of 4 to 5 kg/cm2 is normally applied, it is generally formed by welding a pair of cup-shaped containers formed by deep drawing of a steel plate. Furthermore, since the ambient temperature inside the closed container during operation usually reaches 100° C. or higher, the frame body is formed by casting. Further, the cylinder on which the piston slides is similarly formed of casting, and is fastened to the frame with bolts. Further, the piston, which reciprocates within the cylinder, is connected to a crank pin of a rotating shaft by a so-called ball joint system, and reciprocates within the cylinder.
