Abstract

　スクロール部材の磨耗や変形を低減することが目的とされる。可動スクロールの製造方法は、工程（ａ）と工程（ｂ）とを備える。工程（ａ）では、鋳鉄を成形して、鋳鉄品（２６１）を得る。工程（ｂ）では、工程（ａ）で得られた鋳鉄品（２６１）を削って、可動スクロールを得る。工程（ａ）で得られる鋳鉄品（２６１）は、固定部（２６１ａ）と渦巻き部（２６１ｂ）とを有する。渦巻き部（２６１ｂ）は、固定部（２６１ａ）に固定されており、中心（９）の周りを渦巻き状に延びている。渦巻き部（２６１ｂ）の所定の部分の寸法は、工程（ｂ）の実行後の当該部分の寸法よりも大きい。具体的には、渦巻きの中心（９）側の端（２６１１）の部分（２６１２）について、その厚み（ｄ１）が、工程（ｂ）の実行後の部分（２６１２）の厚み（ｈ１）よりも大きい。
