PURPOSE:To reduce a delivery amount of oil, by arranging a delivery pipe of compressed gas in the intermediate of plural delivery ports so that the deliv ery of compressed gas is directed in an opposite direction to each other, so as to extend a delivery route of the compressed gas and to sufficiently separate the oil. CONSTITUTION:A compressing mechanism part 2, provided in a case 1, is constituted into a two-cylinder type. That is, a compressor provides a shaft 10 penetrating through plural cylinders 3, 4 further mounts plural crank parts 11, 12 in the shaft 10 to be fitted to plural rollers 5, 6. And each roller 5, 6 is provided so as to turn in each cylinder 3, 4 by rotating the shaft 10. While the compressor forms plural delivery ports 16, 17 of compressed gas in a part of plural bearing 13, 14, supporting the shaft 10, so that the delivery ports 16, 17 are formed in parallel with the axial line further with the delivery of the compressed gas in an opposite direction. In the above constitution, a pipe 9 for delivery is arranged in the intermediate of each delivery port 16, 17.
