を特徴とするスクロール型流体機械。 The rotating scroll is composed of a rotating side key that fits into a key groove bored in the rotating scroll, a fixed side key that fits into a key groove bored in the frame, and a ring that integrally connects these keys. In a scroll-type fluid machine equipped with an Oldham ring that allows the scroll to revolve but prevents its rotation, the thickness of the Oldham ring may vary depending on the thickness of the swing-side key and the depth of the keyway into which the swing-side key fits. A scroll-type fluid machine characterized in that the allowable inclination angle of the scroll is limited to 4×10 −3 rad or less.
