とを特徴とするスクロール圧縮機。 In a scroll compressor consisting of a casing having a suction port and a discharge port, a fixed scroll fixed to the casing, and an orbiting scroll rotating opposite to the fixed scroll, the rotation of the orbiting scroll and the fixed scroll occurs during steady operation of the scroll compressor. In order to maintain a predetermined gap between the ends of the wraps, the height of the wraps is reduced by a dimension corresponding to the elongation of the ends of the wraps due to thermal expansion in each part of the scroll's spiral shape. A scroll compressor characterized in that the height on the inside of the wrap is lower than the height on the outside of the wrap in areas where there is a difference.
