にしている。(Prior art) As is known from Japanese Patent Application Laid-Open No. 63-134882, the movable scroll and Oldham ring are both made of aluminum-based light alloy in order to reduce the surface pressure on the sliding part of the key. In order to avoid sliding between metals of the same type, an iron-based casting fitting is cast into the keyway to prevent seizure on the sliding surface. And, as shown in Figure 5,
If the end plate (G) of the movable scroll (0) has a keyway (M) that passes through the top and bottom and is open on the outside, a horseshoe-shaped cast metal fitting (F) that has a U-shape in plan is inserted. That's what I do.

問題が起こる。In addition, as shown in Figure 5 (B), due to manufacturing errors, the cast metal fitting (F) is installed with a deviation between its center (S) and the correct position (T), and later the key When cutting the groove (M), there is a problem that the thickness of the remaining part becomes uneven and the strength decreases in the thin part.In order to avoid this, the same figure is used to ensure the specified thickness even in the thin part. Increasing the size of the metal fittings as shown in (C) not only increases the weight of the metal fittings, but also requires the movable scroll (0) to hold the large metal fittings (F).
It became necessary to provide a reinforcement padding as shown by the imaginary line,
The overall inertial force increases, causing a problem that goes against the reduction in surface pressure on the key sliding portion.
