Description
(ロ)磁性板5の撓みを小さく抑えることにより、従来の磁気シールド簾体6に比し支持部材(支点)の間隔を広げ、磁気シールド簾体6の通気性・透光性を高めることができる。
(ハ)非磁性鞘10の中空部に磁性板5を遊嵌させて位置決めすることにより、非磁性鞘10を用いて複数の磁性板5の長さ方向中心軸Cを容易に位置合わせすることができ、磁気シールド簾体6の施工品質のバラツキを防止することができる。
(ホ)非磁性鞘10の外側表面上の所定部位に鞘10の長手方向に延びる凹入溝16を形成することにより、その凹入溝16を利用して複数のブレード材1の芯合わせの容易化を図ることができる。
(ヘ)非磁性鞘10の表面にカーブをつけることにより、ブレード材1の強度を更に増大させることができる。
(ト)非磁性鞘10を光反射性の材質とした場合でも、非磁性鞘10の表面に細かな溝を設けることにより、光の照り返しを小さく抑えることができる。
