Abstract

PURPOSE:To prevent an eccentric load from acting on the working surface between a main shaft and a baring by constituting the system in such a manner that the first supporting part and the second supporting part of the main shaft becomes eccentric with each other. CONSTITUTION:A main shaft 4 is provided with the first parts 4b, which is supported by a bearing 7, and the second part 4a, which is supported by a bearing 6. The shaft center O1 of the first part 4b is eccentric with the shaft center Os of the main shaft 4, while the shaft center O2 of the second part 4a is also eccentric with the shaft center Os of the main shaft 4. When the main shaft 4 rotates in order to move a movable scroll 3, the compressed fluid is discharged. However, owing to the eccentricity, the first part 4b of the main shaft 4 touches in parallel the bearing 7, while the second part 4a of the main shaft 4 touches in parallel the bearing 6. Accordingly, it is prevented that the bearing 6 or 7 touches the main shaft 4 in a biased manner.
