Description
図1は、本発明の実施例1に係る屈曲構造体を示す斜視図、図2は、同一部を断面にした斜視断面図、図3は、屈曲構造体の端部部材を省略した平面図、図4は、屈曲構造体の内筒及び外筒を示す断面図である。
図5は、屈曲時の内筒3を示す断面図である。なお、外筒5の屈曲は、内筒3の屈曲と同様であるため、図5を参照する。このため、図5では、外筒5の符号を括弧書きで示す。
以上説明したように、本実施例では、第1内コイル部15及び第1外コイル部13からなり、第1外コイル部13の隣接巻部13a間のピッチ13bに第1内コイル部15の対応する巻部15aが嵌合する内筒3と、内筒3の外周を隙間21を有して覆い、第2内コイル部19及び第2外コイル部17からなり、第2外コイル部17の隣接巻部17a間のピッチ17bに第2内コイル部19の対応する巻部19aが嵌合する外筒5と、内筒3及び外筒5間の隙間21を軸方向に挿通してガイドされる周方向に複数の駆動用ワイヤー9a及びガイド用ワイヤー9bと、を備えた。
