PROBLEM TO BE SOLVED: To provide an auxiliary bearing supporting structure of a compressor for a refrigerating air conditioner facilitating the supply of lubricating oil to a compression mechanism, being excellent in reliability, anti-noise performance, anti-vibration performance, assembling performance and the like, having a small number of components and being inexpensive. SOLUTION: An auxiliary bearing 202 has both a plain bearing structure capable of supporting a radial face 210 and a thrust face 211 and part of an oil supply mechanism, and is supported and fixed via a plate 201 fixed to a closed vessel 101 with bolts 203 and the like after vertical centering. By this structure, the lubricating oil 107 is branched, and can be lubricated to the radial face 210 and the thrust face 211. Accordingly, the simple auxiliary bearing structure with a small number of components can be constituted. COPYRIGHT: (C)2005,JPO&NCIPI
