To increase the reliability of a fixed scroll and a rotary scroll of a scroll compressor and also increase the efficiency of the scroll compressor by reducing leakage loss to match the compressor to recent refrigerating air conditioners increased in efficiency and life and using a high-pressure refrigerant such as carbon dioxide.
A spiral seal member 80 is attached to a winding start part of the spiral lap end 12b of the fixed scroll 12. When the scroll compressor is under high load, the tooth bottom of the end plate 13a of the rotary scroll 13 and the winding start part of the lap end 12b of the fixed scroll 12 are deformed, and the winding start part of the fixed scroll 12 is heated and thermally expanded to the rotary scroll 13 side. However, since the seal member 80 is attached to the end of the winding start lap 12b of the fixed scroll 12, nonuniform contact does not occur, and high reliability can be realized.
