- 回転軸に取り付けられたロータと、該ロータの内周面に対向して配置され周方向に所定間隔を隔てて配置された複数の永久磁石を有する内側磁石環と、該内側磁石環とロータとの間に配置された磁性体からなる環状体に周方向に所定間隔を隔てると共に周方向で向き合う磁極が同極となるように埋設された複数の永久磁石を有する外側磁石環とを備え、上記内側磁石環又は外側磁石環のいずれか一方を回転させてロータの制動、非制動を切り替えるようにした渦電流式減速装置において、上記環状体の内周面に、外側磁石環の永久磁石に沿って周方向に延び周方向の両端を永久磁石から延出させる凹部を形成すると共に、該凹部の両端の位置に環状体をさらに深く掘り下げる掘り下げ部を永久磁石を避けて形成したことを特徴とする渦電流式減速装置。
- 上記掘り下げ部は、隣接する永久磁石の径方向の長さの20%以下、かつ、0%より大きい深さに形成された請求項1記載の渦電流式減速装置。
