<P>PROBLEM TO BE SOLVED: To exhibit a sufficient dust preventing function to restrain dust such as sand dust etc., from entering a compressor, and to secure cooling performance that can cool a coupling sufficiently. <P>SOLUTION: The coupling 14 stored in a coupling case 15 couples a compressor drive part 13 with the compressor 12 to transmit a drive force. The compressor 12, the compressor drive part 13, the coupling case 15, a cooling fan 16, and an after-cooler 17 for cooling compressed air compressed by the compressor 12 are housed in the storage case 11. A first air supply path 26 communicates with a path for compressed air led to a compressed air discharge part 19 from the after-cooler 17 and the coupling case 15, and supplies the compressed air cooled by the after-cooler 17 to the coupling 14 so as to be blown out. <P>COPYRIGHT: (C)2012,JPO&INPIT |
