PROBLEM TO BE SOLVED: To provide a scroll fluid machine capable of maintaining a sufficient rotation state.SOLUTION: A scroll expander 1 includes a driving scroll body 6 having a first axis A1 as a rotation axis, a driven scroll body 7 having a second axis A2 eccentric to the first axis A1 as a rotation axis, a bearing plate 8 having the second axis A2 as the rotation axis, a cylindrical driving pin 22 attached to the driving scroll body 6, and a cylindrical guide ring 23 attached to the bearing plate 8 and having an inside diameter larger than an outside diameter of the driving pin 22. The four driving pins 22 are disposed at equal intervals on a circumference with the first axis A1 as a center. The four guide rings 23 are disposed at equal intervals on a circumference with the second axis A2 as a center in such a manner of corresponding to the driving pins 22.SELECTED DRAWING: Figure 2 |
