ABSTRACT:
Rotation interception mechanisms (10) are mounted to intervene between a drive casing (22) and a substrate (60) of a movable scroll (54), and include a binding member (11) for binding rotation of the movable scroll, a fixed side pin (14) provided with protrusion in the drive casing to get engaged with the binding member, and a swivel side pin (15) provided with protrusion in the movable scroll to get engaged with the binding member for being restrained by the binding member and swiveling around a shaft center of the fixed side pin; and load alleviation means (54h) alleviates a load onto the fixed side pin and the swivel side pin caused by the torque due to the distance between the gravity center (O) and the rotation center (OR) of the movable scroll and the centrifugal force.
