A rotation preventing device prevents rotation of an orbiting scroll member of a fluid displacement apparatus during operation. Further, the rotation preventing mechanism includes a pair of annular members that are connected to the orbiting scroll member and has a plurality of bearing elements. Each bearing element is disposed between a pair of annular members. A pair of annular members are in substantial contact with each other at facing surfaces thereof for supporting axial loads imposed on the scroll members. |
