ABSTRACT:
A stationary scroll is provided with a stationary side wrap and an outer peripheral portion. The stationary side wrap is formed into a spiral wall shape. The outer peripheral portion is formed into a ring-like shape enclosing the periphery of the stationary side wrap. A movable scroll is provided with a first flat plate, a movable side wrap, and a second flat plate. The movable side wrap is formed into a spiral wall shape. Additionally, the movable side wrap is caught between the first flat plate and the second flat plate, with the movable side wrap in mating engagement with the stationary side wrap. In the movable side wrap, the first flat plate is formed integrally with the movable side wrap. Additionally, the second flat plate is formed as a separate body from the first flat plate and the movable side wrap and is coupled to the first flat plate with a bolt.
