As shown in FIG. 2, a fixed scroll 3'is provided in a casing 2 ', and a movable scroll 4'which is eccentrically non-rotatingly contacted with the fixed scroll 3'is incorporated into the casing 2', so that the wraps 3A 'and 4'
The space volume formed between A'and A'is changed to compress and drive the fluid. In this structure, an eccentric drive shaft 5'for driving the movable scroll 4'is supported at one end of the casing 2 ', and the eccentric portion 6'makes the eccentric non-rotating motion of the movable scroll 4'. With such an operation, a balance weight B'for dynamic balance is provided near the eccentric portion 6'of the eccentric drive shaft 5 '.

行っていた。By the way, the retainer R'assembled here has a pair of retainer rings (fixed retainer ring 1).
0A ', the movable retainer ring 10B' and the retainer bearing 13 'interposed therebetween are the main constituent members,
Thereby, the movable scroll 4'is supported so as to make a non-rotational eccentric motion. For this reason, extremely high precision is required for machining the retainer ring 10 'in the retainer R', and conventionally, the retainer ring 10 'has been mainly manufactured by cutting. Specifically, a plurality of ball receiving holes 12 ', which are formed at equal intervals, are punched in the starting material to be the ring body 11' by press working, and then the ring inner diameter side is punched by a press and the outer diameter side is A retainer ring 10 'which is also punched by a press and has a large number of ball receiving holes.

なかった。For this reason, there is a limit to increase the production efficiency, and due to this, the production cost must be increased. Even with such a finish, for example, the ball receiving holes are individually finished, so that it is difficult to obtain a product having a perfect accuracy due to distortion or the like during the processing. For this reason, for example, even when incorporated in a scroll fluid machine, the generation of abnormal noise and vibration has not been completely suppressed.
