Abstract
a First gap () in a thrust direction between teeth bottoms of a fixed mirror plate () and teeth tips of an orbiting lap (), and a second gap () in the thrust direction between teeth bottoms of an orbiting mirror plateand teeth tips of a fixed lap () are formed such as to gradually increase from an outer peripheral side to an inner peripheral side of a scroll compressor, the first gap () is made greater than the second gap (). Contact surface pressures of the laps () and () are kept low with respect to pressure formation, contact pressure of the teeth tips of the fixed scroll part () and the teeth bottoms of the orbiting scroll part ()are equally maintained. With this loads applied to the scroll parts () and ()are equally received by a thrust surface.
