<P>PROBLEM TO BE SOLVED: To provide a scroll compressor, which is capable of improving the strength of a winding end portion of a lap, and further which is capable of achieving miniaturization of a compression mechanism. <P>SOLUTION: A lap 26b of a movable scroll 26 describes a spiral shape in which a base radius of an involute becomes smaller as a winding angle increases only in a region extending from a winding start part to a winding middle part, and also describes a spiral shape in which the base radius of the involute becomes larger as a winding angle increases in a region extending from the winding middle part to the winding end part or the base radius of the involute stays constant. <P>COPYRIGHT: (C)2013,JPO&INPIT |
