PROBLEM TO BE SOLVED: To provide a scroll type compressor for a fuel cell allowing significantly reducing noises such as a whizzing sound when rotating a rotation balancer. SOLUTION: This scroll type compressor 100 is formed by a drive motor 130, a drive crankshaft 131, a fixing scroll 110, a turning scroll 120 and the rotation balancer W mounted for reducing unbalance originating from a turning movement of the turning scroll. The rotation balancer is approximately fan- shaped and at least a part of its front end face abutting on surrounding gas at rotating is formed in a smooth curved surface. Since at least the part of the front end face is formed by the smooth curved surface, air flow generated when rotating the rotation balancer becomes smooth for reducing generation of the whizzing sound. |
