<P>PROBLEM TO BE SOLVED: To materialize a hermetic compressor compatibly achieving both of improvement of efficiency of an electric motor and reduction of oil discharge. Ž<P>SOLUTION: Deformation of a hermetic vessel 1 due to pressure is reduced by a structure in which a groove 9 extending in a cylinder axial direction is provided on an inner wall of the hermetic vessel 1 and skew is given on the groove. Thereby, a stator is prevented from coming off during operation, efficiency of the electric motor is secured since the stator is kept in a round shape, and refrigerant and oil are separated by centrifugal force and quantity of oil discharged to an outside of the hermetic vessel 1 is further reduced since refrigerant gas flows in turning flow.
