Object: To provide a scroll type fluid machine which can suppress increase of inclining vibrations of an Oldham ring with facilitated adjustments. Construction: A stationary scroll (1) and a swivel scroll (2), in a pair, are engaged with each other and said swivel scroll (2) is driven to make revolutional motions, while prevented from making rotations, via an Oldham ring (18) disposed between an end plate (6) of said swivel scroll (2) and a frame (10) and, where a distance between said end plate (6) of the swivel scroll (2) and said frame (10) is s and a thickness of a ring portion (19) of said Oldham ring (18) is t, a gap delta , formed as (s-t), to a radius r of said ring portion (19) of the Oldham ring (18) is set so that delta /r is 0.01 or less. Thus, only by the ring portion (19) of the Oldham ring (18) being adjusted of its thickness, increase of inclining vibrations of an Oldham ring (18) can be suppressed. <IMAGE> |
