PROBLEM TO BE SOLVED: To stably and firmly weld and fix a supporting leg to the bottom of a sealed container having a curved face in an inexpensive manner. SOLUTION: The curved face of the bottom of the sealed container is differentiated in shape from the supporting face of the supporting leg, the supporting leg before welded in a state of being installed on the bottom of the sealed container is made to abut on the bottom at the supporting face of the supporting leg near a compressor mounting hole, and a gap is formed in a welding position at the end of the supporting face between the bottom of the sealed container and the mounting face of the supporting leg. Thus, when the sealed container is welded to the supporting leg, molten metal enters into the gap between the bottom of the sealed container and the supporting face of the supporting leg during welding to cover a wide range of welding position and produce firm welding strength. There is no possibility of deviation from an abutment position between the bottom of the sealed container and the supporting face of the supporting leg even when distortion occurs after welding, achieving the stable fixing strength of the supporting leg.
