PURPOSE: A bearing structure is provided to significantly reduce a frictional loss and eliminate a process of finishing a thrust surface by installing, between a crankshaft and a frame, a bearing structure that utilizes a magnetic member having the same polarity. CONSTITUTION: A structure comprises a bearing unit(60) disposed between a frame(51) and a crankshaft(52) so as to support a rotation axis(50) of a compressor, wherein the bearing unit is provided with magnetic members(61a,61b) having same polarity, the magnetic members being fitted into holes formed at the frame and crankshaft. Thus, a frictional loss produced during a rotation of the compressor can be reduced regardless of oil supply.
