<P>PROBLEM TO BE SOLVED: To solve large problems of reliability of a conventional scroll compressor wherein since the bush of a rotary bearing installed in the rotary scroll of the scroll compressor is of press-fit type, the bush is easily moved by the pressure of a refrigerant and due to a friction from a crankshaft when in actual use (heated). Ž<P>SOLUTION: A guide 8 of the same material as the bush 12 (or the back plate) or a guide 8 having a coefficient of thermal expansion equal to or lower than that of the bush 12 is attached to the outer peripheral part of the housing of the rotary bearing part 11 of the rotary scroll 1. Since the inner diameter dimension of the housing is prevented from being increased, the rotary bearing bush 12 attached to the rotary scroll 1 in the actual use is not moved. Consequently, the highly reliable scroll compressor having the rotary scroll can be provided at low cost. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
