PROBLEM TO BE SOLVED: To reduce a rotary direction vibration generated due to torque fluctuation with a simple structure in order to solve such a problem that a method positively reducing vibration value of a hermetic vessel is not adopted to a former compressor and that the hermetic vessel of the compressor vibrates. SOLUTION: In this hermetic compressor, magnets 50 are attached in a circumference direction and a radial direction of an accumulator 13 of the hermetic compressor comprising an electric motor part, a compressor mechanism part driven by the electric motor part, the hermetic vessel 10 storing the compression mechanism part, an accumulator 13 and legs 11 supporting the same. Consequently, the weight of the accumulator part is increased and inertia moment is increased to reduce rotary direction vibration of the compressor over whole operation frequency.
