Abstract
In a scroll compressor, a thrust bearing is movably held and urged to support thrust force of an orbiting scroll member against a fixed scroll member within a predetermined stroke in the axial direction of the scroll members, thereby to always allow desirable minute gap and also allow to move back against the urging force to reduce abnormal pressure in a compression chamber.
