ABSTRACT:
Joint guides comprise mutually opposing guide portions formed on a casing and mutually opposing guide portions provided on an orbiting scroll member. A plate spring is integrally attached to a part of each guide portion. Even when a load due to rotational torque from the orbiting scroll member acts on each slider from a loading-side guide portion, resilient force from the plate spring presses a sliding surface of the slider toward a sliding surface of the loading-side guide portion, thereby preventing the formation of a gap between the sliding surface of each slider and a convexly curved portion of the associated plate spring or between the sliding surface of each slider and the sliding surface of the associated guide portion, and thus preventing the occurrence of a rattle.
