A muffler cover of a compression element has discharge outlets or hole portions that discharge a compressed refrigerant gas into a closed vessel from a compression element. A suction pipe provides refrigerant gas, which can be sucked into the compression element in the closed vessel. The suction pipe is attached to the closed vessel. A first direction and a second direction, which correspond to natural vibration modes of the suction pipes, do not coincide with a direction that connects two hole portions. Therefore, even if the refrigerant gas discharged from the compression element resonates in the closed vessel, vibrations of the suction pipe can be reduced. |
