ABSTRACT:
A scroll compressor has a movable auxiliary member provided by mounting it between a frame member and a circling scroll member. The movable auxiliary member has a stopper portion for causing a contact plane to contact a pane of a fixed scroll member and a ring portion having an opposed plane annularly formed to face the pane of the circling scroll member, is further supported elastically by an elastic support in a state of being energized in a direction of the circling scroll member, has the contact plane of the stopper portion caused to contact the pane in this elastic support state to keep a limit position with the opposed plane facing the pane of the circling scroll member, and goes back elastically to the frame member side when the circling scroll member goes back to the frame member side and the pane is pressed to contact the opposed plane.
