SCROLL COMPRESSOR

PROBLEM TO BE SOLVED: To provide a scroll compressor capable of shortening processing time of swirl vanes and reducing manufacturing cost, while keeping the intensity and the function of swirl vanes having structure of vane thickness with stage. SOLUTION: The scroll compressor is to have the structure where the central part of swirl vanes of a scroll is made into structure with the lower stage and upper stage of a thinner vane than the lower stage. In the scroll compressor which a stage face is formed between the lower stage and upper stage, the slope may be formed in any one at least on outside corner between the side of the lower stage and the stage face as well as the outside corner between the side of the upper stage and the upper end surface of upper stage. Thereby, it makes possible to minimize excess thickness of raw material (machining allowance). Since the processing accuracy of the side, upper surface and stage face of swirl vanes is equivalent to that of the conventional one, the processing time of the swirl vanes is shortened and manufacturing cost is reduced, maintaining the intensity and the function of swirl vanes of conventional structure having thick vane with stage.
