Abstract

　合成樹脂製のセンサホルダ７ａの熱膨張又は熱収縮に拘らず、センサ６ａ、６ｂとエンコーダ４ａとの間に、測定誤差に結び付く、有害な軸方向の相対変位が生じる事を抑えられる構造を実現する。 　上記センサホルダ７ａは、上記センサ６ａ、６ｂを保持した部分が円環状である。この円環状部分の軸方向中間部に、金属製のカバー５ａを構成する円筒部１２ａの内周面に大きな締り嵌めで内嵌固定した保持環２７を包埋固定する。この保持環２７の折れ曲がり部２９の軸方向位置を、上記両センサ６ａ、６ｂの検出部の軸方向位置の丁度中央位置とする。この構成により、上記熱膨張又は熱収縮が、上記両センサ６ａ、６ｂの出力信号の位相差に結び付かない様にして、上記課題を解決する。
