ABSTRACT:
The inner circumference 4a2 of the bearing ring 4a is square-shaped, and the outer circumference 4a3 thereof is circular. The shoulder 1a1 of the attaching portion 1a of the scroll member 1 is formed to be square-shaped, corresponding to the inner circumference 4a2 of the bearing ring 4a. When attaching the bearing ring 4a to the attaching portion 1a, the square-shaped inner circumference 4a2 of the bearing ring 4a is fitted to the square-shaped shoulder 1a1 of the attaching portion 1a. Thus, by fitting the inner circumference 4a2 of the bearing ring 4a to the shoulder 1a1 of the attaching portion 1a, the bearing ring 4a is prevented from rotating with respect to the swivel scroll member 1.
