Document Type and Number:
WIPO Patent Application WO/2017/057159
Kind Code:
A1
Abstract:
[Problem] To provide a scroll-type compressor with which degradation of bearing durability can be prevented while avoiding cost increase. A scroll-type compressor 1 is provided with: a fixed scroll member 21; a revolving scroll member 22; a drive shaft 12 for transmitting rotational power; an eccentric shaft 17 provided in a position that is misaligned from the axial center of the drive shaft 12; a radial bearing 24; and a bushing 23 provided with an insertion hole 23a into which the eccentric shaft 17 is inserted, the bushing 23 being fitted over the eccentric shaft 17 via the insertion hole 23a, and supported so as to be capable of rotating relative to the radial bearing 24 and the eccentric shaft 17. Formed in one axial-direction end of the drive shaft 12 is a fitting hole 12a that fits with the eccentric shaft 17, the eccentric shaft 17 and fitting hole 12a being fitted together with a loose fitting.
