  However, the liquid-side operation valve 61 and the gas-side operation valve 62 are in a state in which the pair of screw holes 35c for fixing screws and the pair of screw holes 35d for fixing screws are shifted laterally from each other. Since the support member 30 is lined up in the longitudinal direction (lateral direction) and supported by the front portion of the compressor chamber, the compressor can be used in a range where the liquid side operation valve 61 and the gas side operation valve 62 are arranged in the horizontal direction. Since it occupies so as to block the front part of the chamber, there is a problem that the opening of the front part of the compressor room cannot be sufficiently secured, and maintenance of the compressor room cannot be performed satisfactorily.

  Further, the support member 30 has a strength by forming a stepped portion 37 between the mounting portion 35 and the interference preventing portion 36 and forming a plurality of groove portions 38a, 38b and 38c extending in the longitudinal direction (lateral direction). For example, the hex nut provided in the service port 61b or 62b of the operation valve 61 on the liquid side or the operation valve 62 on the gas side is tolerated with torque when fastened with a wrench (not shown). In addition, it is insufficient to provide sufficient strength so that the portion does not deform.
