A scroll compressor with two scrolls including respective scroll wraps to form a compression chamber therebetween so that a volume of the compression chamber is decreased to compress a fluid therein by an orbital motion between the scrolls around an axis, has a frame supporting the scrolls thereon, a drawing force generator generating a drawing force urging axially one of the scrolls toward another one thereof, and a contacting force limiter bearing at least a part of the drawing force to prevent the at least a part of the drawing force from being born by a contact between the scrolls, when an axial distance between the scrolls is not more than a predetermined axial distance.

[ What is claimed is:] [1.] A scroll compressor comprising,two scrolls including respective scroll wraps to form a compression chamber therebetween so that a volume of the compression chamber is decreased to compress a fluid therein by an orbital motion between the scrolls around an axis,a frame supporting the scrolls thereon,a drawing force generator generating a drawing force urging axially one of the scrolls toward another one thereof, anda contacting force limiter bearing a part of the drawing force to prevent the part of the drawing force from being borne between the scrolls, when an axial distance between the scrolls is not more than a predetermined axial distance, wherein the drawing force generator includes a thrust bearing which is provided adjacent the one of the scrolls to apply the part of the drawing force therethrough to the one of the scrolls so that the one of the scrolls is urged axially toward the another one of the scrolls, and the contacting force limiter prevents an axial distance between the another one of the scrolls and the thrust bearing from being less than another predetermined axial distance so that the contacting force limiter bears the part of the drawing force to prevent the part of the drawing force from being borne between the scrolls when an axial distance between the scrolls is not more than the predetermined axial distance, wherein another part of the drawing force is borne by a contact between the scrolls.
