Summary:PROBLEM TO BE SOLVED: To improve the reliability of the key sliding part of a scroll compressor by preventing the abnormal wear or seizure of the key sliding part of the Oldham's coupling (39) even in the case of the high speed operation of a scroll compressor comprising a fixed scroll, a movable scroll to be turned by a predetermined revolution radius with respect to the fixed scroll, and the Oldham's coupling (39) for allowing the revolution movement of the movable scroll while prohibiting the rotation movement thereof with the Oldham's coupling (39) comprising an annular ring (39a), and keys (39b, 39c) formed on the axial direction end face of the ring (39a).SOLUTION: By forming keys (39b, 39c) with materials having density higher than that of a ring (39a), the entirety of an Oldham's coupling (39) is made light in weight and the seizure resistance of the keys (39b, 39c) is improved.
