体機械のオルダム継手。 In an Oldham joint that is interposed between an orbiting scroll and a frame of a scroll-type fluid machine and allows the orbiting scroll to revolve but prevents its rotation, a flat ring is connected to a flat ring from the center of the outer surface of the end plate of the orbiting scroll. An elongated hole having a pair of parallel surfaces that slidably engages with a pair of parallel surfaces provided opposite to the outer periphery of the protruding boss is bored, and a hole parallel to the elongated hole is formed from the outer periphery of the flat ring. 1. An Oldham coupling for a scroll type fluid machine, characterized in that a pair of fixed side keys are provided which extend in a direction perpendicular to the plane and are slidably fitted into key grooves bored in the frame.
