Abstract
In a scroll type fluid machine comprising a compressor housing, a front end plate (4) fixed within the compressor housing, a fixed scroll member, and a movable scroll member (14), an Oldham ring (26) is placed between the front end plate and the movable scroll member to prevent self-rotation of the movable scroll member. The Oldham ring comprises a plurality of keys (26a, 26b). The front end plate and the movable scroll member have housing keyways (4a) and scroll keyways (15a), respectively, formed therein, for receiving the keys. A pair of semi-circular members (40a) are assembled to form a ring member on at least one of the front end plate and the movable scroll member and receives a thrust load acting on the movable scroll member. The semi-circular member has ends bent to form bent sections (40b). The bent sections are inserted into the housing keyway or the scroll keyway. The key is within the housing keyway or the scroll keyway when the bent section is within the keyway to receive sliding of the key.
