Abstract:
[Problem] To reduce imbalance among all movable components of a scroll compressor including a drive shaft and components fixed or connected to the drive shaft. In a scroll compressor 10, a shaft balancer 31 integrated with a drive shaft 30 includes a first weight 33 disposed on the opposite side from an eccentric pin 71 with respect to a center line CL0 of the drive shaft 30, and a bushing balancer 721 integrated with an eccentric bush 72 includes a second weight 723 disposed on the radially outer side of the eccentric bush 72 and on the opposite side from a center line CL1 of the eccentric pin 71 with respect to a center line CL2 of the eccentric bush 72. In a view from the axial direction of the drive shaft 30, the second weight 723 is symmetric with respect to a virtual line passing through the center of the drive shaft 30 and the center of the eccentric bush 72, and the first weight 33 is asymmetric with respect to the virtual line.
