Abstract
A scroll compressor includes fixed and movable scrolls, each scroll having a spiral lap placed on one surface of a plate. The lap of the fixed scroll and the lap of the movable scroll are interlocked to form a compression chamber between the laps of the scrolls which are adjacent to each other. At least one of the laps has a spiral shape in which a base radius of an involute decreases as a winding angle increases in a region extending from a winding start part to a winding middle part, and the base radius of the involute in a region extending from the winding middle part to a winding end part is larger than the smallest value of the base radius of the involute in the region extending from the winding start part to the winding middle part.
