Abstract (en)
In scroll compressor (100), eccentric shaft (13a) is fit in orbiting bearing (13d) of orbiting scroll (12) to make orbiting scroll (12) rotate, and orbiting bearing (13d) or eccentric shaft (13a) has a tapered shape. This shortens the distance between a point at which orbiting scroll (12) receives a compression load and a point at which eccentric shaft (13a) presses orbiting bearing (13d) while rotating to reduce a turning moment that acts on orbiting scroll (12), and thereby the behavior of orbiting scroll is stabilized and a highly efficient and highly reliable scroll compressor can be provided.
