Abstract:
A method of manufacturing a scroll member includes a casting step and a cutting step. In the casting step an iron casting having a spiraling part is formed. In the cutting step, the iron casting obtained in the casting step is cut to obtain a final shape of the scroll member. Preferably the iron casting obtained in the casting step has a fixing part with the spiraling part extending from one side and a protruding part extending from an opposite side. A specified portion of the spiraling part, a central portion of the fixing part and/or the protruding part has a larger dimension before the cutting step is performed than after the cutting step is performed.
