Zusammenfassung:	PURPOSE:To attain compactness and light weight and reduce the load of a main bearing, inertial force, vibration and oil agitating action caused by a balance weight by improving the shape and position relation of the Oldham's coupling and balance weight of a scroll compressor. CONSTITUTION:A ring-shape Oldham's coupling 5 is provided between a turning scroll 2 and the key groove base seat 4b of a frame 4 supporting a fixed scroll 1. A rotary shaft 3 provided with a crank pin 3a fitted to the boss 2c of the turning scroll 2 is supported on the frame 4 by a main bearing 4a. A balance weight 6, fitted to the rotary shaft 3 between the boss 2c and the main bearing 4a, is provided with an axially protruding weight part 6a protruded to the ring inner side of the Oldham's coupling 5, and a radially protruding weight part 6b positioned below the key groove base seat 5b. The ring of the Oldham's coupling is formed into elliptical shape in such a way as to keep constant small clearance to the outer peripheral turning locus of the weight part 6a.
