<P>PROBLEM TO BE SOLVED: To provide a compressor capable of preventing seizure between a rear shaft of a shaft and a rear bearing, by reducing a surface pressure between the rear shaft of the shaft and the rear bearing. <P>SOLUTION: The diameter R2 of a rear shaft 12b of a shaft 12 is smaller than the diameter R1 of a front shaft 12a of the shaft 12. The rigidity of rear-side elastic sections 64 is less than the rigidity of front-side elastic sections 54. When this compressor is operated, the deflection of the rear shaft 12b is greater than the deflection of the front shaft 12a. However, the elastic deformation of the rear-side elastic sections 64 is capable of becoming larger than the elastic deformation of the front-side elastic sections 54. Thus, the surface pressure between the rear shaft 12b and the rear-side elastic sections 64 can be reduced, and seizure of the rear shaft 12b and rear bearings 60 can be prevented. <P>COPYRIGHT: (C)2013,JPO&INPIT |
