PROBLEM TO BE SOLVED: To obtain a compressor capable of suppressing removal of refrigerator oil from the compressor as compared with a conventional compressor.SOLUTION: A high-pressure shell type compressor 100 includes: an electric mechanism 10 in which a counter bore 13 is formed under a rotor 12; a driving shaft 2 in which a passage 2a of refrigerator oil and a gas-vent hole 3 connected to the passage 2a and opened into the counter bore 13 are formed; a compression mechanism 1 arranged under the electric mechanism 10; and a closed vessel 20 which stores these units and forms an oil reservoir on a lower part. In plain view, a distance from a center axis of the driving shaft 2 up to an outer peripheral part of the counter bore 13 is shorter than a distance from the center axis of the driving shaft 2 up to a discharge port 6 of the compression mechanism 1, and an upper bearing 4 of the compression mechanism 1 is arranged so that its upper end part is inserted into the counter bore 13. |
