Abstract:
Provided is a scroll compressor that pushes a movable scroll against a fixed scroll by means of a floating member, wherein the tilt of the floating member can be minimized, and the number of assembly and manufacturing steps can be minimized. A scroll compressor (100) is provided with a compression mechanism (20), an electric motor (70) that drives a movable scroll (22), a drive shaft (80) that links the movable scroll and the electric motor, a casing (10), a housing (40) accommodated inside the casing, and a floating member (30) that pushes the movable scroll against a fixed scroll (21) by means of a back pressure space formed between the floating member and the housing. In this scroll compressor, either: (A) the floating member has a plurality of bushes (37a) disposed in a circumferential direction, and a support part (41) of the housing supports the bushes so as to enable the bushes to slide in the axial direction of the drive shaft; or (B) the floating member has a main body member and an outer peripheral member that, as a separate member from the main body member, is attached to the outer periphery thereof, and the housing supports the outer peripheral member so as to enable the outer peripheral member to slide in the axial direction of the drive shaft.
