Claims

[Claims for Utility Model Registration] (1) A scroll-type fluid machine in which a fixed scroll 3 is fixedly supported on a frame 2, and a movable scroll 4 is supported via a thrust plate 5 so as to be rotatable. , the frame 2 has a support surface 21a that supports the back surface 51 of the thrust plate 5, and an outer surface 5 of the thrust plate 5.
The spigot part 2 has a locking surface 21b that locks the spigot part 2.
1, the thrust plate 5 is attached to this spigot part 21, and the support surface 2
Scroll type characterized in that a corner 21c where the thrust plate 1a and the locking surface 21b intersect is formed with a stolen portion 21d that prevents the back surface 51 from riding on the support surface 21a when the thrust plate 5 is attached. Fluid machinery. (2) A scroll-type fluid machine in which a fixed scroll 3 is fixedly supported on a frame 2, and a movable scroll 4 is supported so as to be able to revolve around a thrust plate 5, wherein the fixed scroll 3 is fixedly supported on a frame 2; A spigot part 22 having a support surface 22a that supports the end mounting surface 31 of the scroll 3 and a locking surface 22b that locks the end outer surface 32 of the fixed scroll 3 is formed. A corner portion 22c where the supporting surface 22a and the locking surface 22b intersect is provided with a corner portion 22c on which the fixed scroll 3 is mounted, and which prevents the mounting surface 31 from riding on the supporting surface 22a when the fixed scroll 3 is mounted. A scroll-type fluid machine characterized by forming 22d.
