Abstract

PURPOSE:To make it possible to facilitate the deburring of an annular member by providing such an arrangement each of a plurality of key-like projections constituting an Oldham's coupling serving as a rotation preventing mechanism for a rotary scroll, has a root section attached to the annular member and having a diametrical width which is set to be smaller than the diametrical width of the annular member. CONSTITUTION:A compressor mechanism section is composed of a stationary scroll 1, a rotary scroll 2 supported on a crank shaft 3 through the intermediary of a bearing 2a and an Oldham's mechanism serving as a rotation preventing mechanism. Further, the Oldham's mechanism is composed of a key groove formed in the rear surface of the rotary scroll 2, a key groove formed in a stationary pedestal 4b on a frame 4 and an Oldham's coupling 5 in which a plurality of key-like projections 6a, 6b adapted to slide in the key groove in the rotary scroll are formed on the upper and lower surfaces of the annular member 6. In this arrangement, each of the projections 6a, 6b has its root section attached to the annular member and having a diametrical width (h) that is set to be smaller than the diametrical width H of the annular member 6.
