ABSTRACT OF THE DISCLOSURE A scroll compressor according to the present invention has a fixed scroll member and an orbiting scroll member, the latter being arranged in a juxtaposed relation with the former so that wraps thereof are fitted closely together, an electric motor having a driving shaft, and a swing link between the orbiting scroll member and the electric motor for delivering a rotational force of the electric motor to the orbiting scroll member. The swing link has an opening for receiving a boss of the orbiting scroll member and an eccentric opening to receive a driving pin of the driving shaft so that the orbiting scroll member orbits but does not rotate relative to the fixed scroll member. In the present invention, the swing link, which has a novel feature in a positional relation between the eccentric opening and the boss opening of the swing link, has a first member which is a main portion of the swing link and a second member which is a balance weight movably attached to the first member. The balance weight is limited in its movement in a radius direction of the rotary shaft.
