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. |
