PROBLEM TO BE SOLVED: To inexpensively and surely cancel thrust force applied to a driving scroll and a driven scroll of a scroll fluid machine with a simple structure.SOLUTION: A driving scroll 6 and a driven scroll 8 are eccentrically borne. A driven scroll cap 9 is disposed on the driven scroll 8 in such a manner of storing the driving scroll 6 between the driven scroll 8 and it, and is borne concentrically with the driven scroll 8 and eccentrically with the driving scroll 6. Thrust receiving materials 23 and 24 are arranged between an end plate 17 of the driven scroll cap 9 and an end plate 13 of the driving scroll 6, and regulate movement of the driving scroll 6 in a separating direction with respect to the driven scroll 8. The thrust receiving materials 23 and 24 are constituted by a first thrust ring 25 fixed to the end plate 13 of the driving scroll 6 and a second thrust ring 27 fixed to the end plate 17 of the driven scroll cap 9, for example. |
