Zusammenfassung:PROBLEM TO BE SOLVED: To achieve miniaturization of a helical compressor and reduce sliding resistance caused by revolution of a revolving body. SOLUTION: A disk shaped front side closing body 12 is joined to a front end surface of a cylinder 11, and a disk shaped rear side closing body 13 is joined to a rear end surface of the cylinder 11. The cylinder 11, the front side closing body 12 and the rear side closing body 13 constitute a whole housing 10. A recessed part 213 formed on a rear end surface 212 of a rotating body 18 communicates with a delivery path 122 through a ring space 233 of a radial bearing 23, the cylinder inside 181 of the rotating body 18, a ring space 223 of a radial bearing 22, and a space ρ between a front end wall 20 of the rotating body 18 and the front side closing body 12.
