Title
(JA) エンコーダ及びその組立方法、駆動装置、並びに車両用操舵装置
Abstract
(JA)

回転軸に取り付けられて、前記回転軸の回転情報を検出するためのパターンが形成された回転体と、前記回転体の前記パターンを検出する検出部と、前記検出部の検出結果に基づいて、前記回転軸の前記回転情報を求める演算部と、を備えるエンコーダであって、前記回転体は、前記回転軸の回転方向に沿って、それぞれ前記パターンの一部が形成された複数のパーツ部に分割されているものである。一端部に操作部が設けられ、他端部がモータに連結されたような回転軸を有する駆動部のその回転軸に対し、エンコーダを取り付けたり、又は取り外したりすることができる。
