摘要： PROBLEM TO BE SOLVED: To prevent breakage of a sealing member and thereby to implement good sealing performance. SOLUTION: A regulating mechanism 20 for regulating a position in an axial direction of a thrust ring 17 is provided. In the regulating mechanism 20, a stepped portion 21 is formed by cutting out an upper portion of an outer peripheral wall 43 constituting a separation room groove 42, and an extending portion 22 is formed by extending the thrust ring 17 in a radial direction. When a turning scroll 8 pushes down the thrust ring 17 at a time of turning, the extending portion 22 of the thrust ring 17 is engaged with the stepped portion 21, so that a state of the sealing member 16 is kept to be a tolerance or higher, resulting in preventing the thrust ring 17 from pushing down the sealing member 16 to be the tolerance or lower.
