PROBLEM TO BE SOLVED: To eliminate installation of an oil pumping up means such as a paddle by enlarging a centrifugal force generated by rotation of a rotational shaft and to reduce costs. SOLUTION: In this compressor, inside a closed vessel having an oil reservoir 7 on the bottom part, a compression element 3, an electric element 4, and the rotational shaft 5 having an oil supply hole 17 for supplying oil in the oil reservoir 7 to a sliding part of the compression element 3 and transmitting rotation of the electric element 4 to the compression element 3 are stored. A center 30 of an oil supply hole 17A in the lower part side of the oil supply hole 17 is provided, so as to be deviated by 1.6 mm from an axial center 50 of the rotational shaft 5 and be inclined to the axial center 50 at 1.2°in the approximately deviated direction.
