A second muffler cover (240) of a compression element (2) has two hole portions (240a) that discharge a refrigerant gas into a closed vessel (1). A suction pipe (11) that sucks the refrigerant gas is attached to the closed vessel (1). A first direction (D 1 ) and a second direction (D 2 ) of natural vibration mode of the suction pipe (11) do not coincide with a direction (D 0 ) that connects the two hole portions (240a). Therefore, even if the refrigerant gas discharged from the compression element (2) resonates in the closed vessel (1), vibrations of the suction pipe (11) can be reduced. |
