Abstract

　内面の腐食を防止することができ、かつ製品外観を良好とすることができる中空コイルばねおよびその製造方法を提供する。　端部封止工程では、ばね材Ｗの端部Ｗａの肉を加工により集めて端部Ｗａを封止する。加工としてスピニング加工を行うことが好適である。たとえば絞り用ローラＲによってばね材Ｗの端部を径方向内側に向かって押圧しながら、必要に応じて適宜絞り用ローラＲを軸線方向に移動させる。これによりばね材Ｗの端部Ｗａは、図３に示すように閉塞されるから、蓋部材等の別部材を用いる必要がない。このような端部封止工程は、たとえば内表面処理工程を行った後、直ぐに行うことができる。端部封止工程後のコイル成形工程では、ばね材Ｗの端部Ｗａを把持してばね材Ｗをロッドに巻き付ける場合でも、端部Ｗａでの隙間形成が防止される。
