摘要： PROBLEM TO BE SOLVED: To arrange a balance weight at the space between a turning scroll rear surface and a frame and to achieve a configuration where oil for lubricating each shaft support section cannot be easily mixed to working fluid after passing a suction opening, in a scroll fluid machine in a cantilever bearing structure. SOLUTION: A second frame 101 is arranged between a first frame 100 and the turning scroll 3, and center section spaces 114-116 and outer periphery section spaces 117, 118 are sealed by a sealing section (sealing material 113) formed between a turning scroll shaft support end face 122 and the second frame 101. Additionally, the balance weight 105 is arranged at the space 116 between the lower portion of the second frame and the first frame. As a result, nearly all oil after lubricating each shaft support section flows into the lower space 116 in the second frame, and oil stored here is discharged to an oil well section 10 at the lower portion of the sealed container via a drainage pipe 103. Additionally, the balance weight can be assembled from the turning scroll side while the second frame is removed, so that the balance weight can be installed close to the turning scroll.
