PROBLEM TO BE SOLVED: To improve reliability by improving compression efficiency and mechanical efficiency. SOLUTION: A clearance G is formed between each of cylinders 9, 10 and an inwall of a closed container 1 by fixing a bearing 15 on the inwall of the closed container 1 and fixing the cylinders 9, 10 on the bearing 15. Consequently, the closed container 1 is content-volumetrically designed roomy and reliability is improved, and it is possible to improve compression efficiency and mechanical efficiency by a compact multiple cylinder rotating compression element 3.
