To improve cooling efficiency of a compressor main body by circulating cooling air in a package to efficiently cool the compressor main body.
An air intake port 8 taking air into a package 1 from an outside is positioned and provided on another end side on an axially opposite side to a cooling air inflow port 30 of a cooling air guide 26 in the package 1. Consequently, air taken in from the air intake port 8 can be introduced from the cooling air inflow port 30 of the cooling air guide 26 via a periphery of the compressor main body 12. Moreover, the compressor 12 can circulate cooling air toward an outflow port 31 from the inflow port 30 in the cooling air guide 26. Consequently, the compressor main body 12 can be efficiently cooled by flow of two systems of cooling air flowing in the package 1 and cooling air flowing in the cooling air guide 26.
