The auxiliary weight portion is arranged on the outer side of the cylindrical portion. The fitting hole is provided at a position where a moment about the eccentric shaft generated by a centrifugal force acting on the movable scroll due to rotation of the rotary shaft and a moment about the eccentric shaft generated by a centrifugal force acting on the auxiliary weight portion due to rotation of the rotary shaft are in the opposite directions. As viewed in the axial direction of the rotary shaft, the center of gravity of the bushing is located on the same side of a straight line including the center of the cylindrical portion and the center of the rotary shaft as the center of the eccentric shaft.
