PROBLEM TO BE SOLVED: To facilitate the structure of an overall compressor by connecting an electric motor to a compressor body through a cooling fan to reduce the number of parts for connection. SOLUTION: The cooling fan 14 connecting the output shaft 2 and the rotating shaft 6 of the electric motor 1 and the compressor body 3 is installed between the electric motor 1 and the compressor body 3. In this case, the output shaft 2 is connected to the cooling fan 14 in a swingable state relative to an axis O-O by a coupling 15, and the rotating shaft 6 is fitted into the rotating shaft fitting hole 21 of the cooling fan 14 through a key 17. When the compressor is operated, the compressor body 3 is driven by the electric motor 1 through the cooling fan 14 while the compressor body 3 is cooled by the cooling fan 14. Thus, with a simple structurer, the electric motor 1 can be connected to the compressor body 3 through the cooling fan 14, and the workability in assembling the compressor and the maintainability in disassembly and repair can be increased.
