PROBLEM TO BE SOLVED: To solve problems of a swirel scroll with double teeth a through hole for a shaft, that: an outer diameter is enlarged because an autorotation prevention mechanism is obliged to be installed on the outside of a spiral lap in a constitutional requirement; durability of bearing load is lowered because gas compression load and centrifugal force of two pairs of compression mechanisms act in the same direction; and performance and durability are lowered because the rotating lap is formed integrally on both faces of end plates of the low rigidity swirel scroll to increase deformation at a time of machining and operation. SOLUTION: This multiple connection type scroll compressor has compression chambers formed in such a manner that two fixed scrolls with double teeth are meshed with two swirel scrolls. Each fixed scroll with double teeth is constituted by connecting back faces of end plate of two fixed scrolls having spirals of opposite winding direction to each other. In the swirel scroll, spiral projection of which planner shapes of rotating laps have respective equal mirror images, and a bearing boss having a rotating bearing arranged on load center and the through hole for a shaft which are erected on the edge plate. The multiple connection type scroll compressor has two pairs of the compression mechanism portions constituted of the shaft with two rotating shafts opposite to and eccentric with each other and an autorotation prevention mechanism.
