(54) COMPRESSOR


(57) a cylindrical housing (11) extending in an axial direction (Da) and in which an opening (19) is formed in a side wall surface of the housing (11); a suction pipe (18) which allows a refrigerant to be suctioned into the housing (11); and a discharging pipe (50) which allows the refrigerant compressed by a scroll compression unit (30) in the housing (11) to be discharged to the outside of the housing (11). The discharging pipe (50) includes a discharging pipe main body (51) having a linear shape passing through the opening (19) so as to be extended in a radial direction (Dr) outward the housing (11) from an inside thereof. An inner peripheral surface of the opening (19) is separated from an opening facing portion (51d) facing the inner peripheral surface in an outer peripheral surface of the discharging pipe main body (51).
