PROBLEM TO BE SOLVED: To provide a scroll compressor capable of preventing degrading of compression performance due to leakage caused by torsion assembling errors. SOLUTION: The scroll compressor has a fixed scroll having volute laps with the same tooth thickness Tr formed by an involute curved surface respectively specified with the same base circle radius b on an end plate, and a turning scroll, wherein they are set up to be mutually eccentric at a turning radiusρonly and both scrolls are engaged with each other while respective laps are opposite by shifting both phases at 180°only and the turning scroll compresses the gas by making a revolution turning operation on a circle track as a turning radiusρwhile the spontaneous rotation of the turning scroll is prevented by a spontaneous rotation prevention mechanism. The relative relationship of spiral lap involute curves of both scrolls, and dimensions, dimensional tolerances, and assembling criteria of the self-rotation prevention mechanism are fixed so as to make an upright position of the turning scroll and a central value of a permissible self-rotation angleϕcoincide with each other.
