Abstract
【解決手段】 レンズ鏡筒内での位置調整が行われる絞りユニット2と、絞りユニット2に電気接続され、絞りユニットを位置調整する円周方向に延長配置されているフレキシブル回路基板4を備え、フレキシブル回路基板4は内周面に低反発材料からなる低反発層44を一体に有する。絞り調整を行うためのモータ3を円周方向に位置調整したときにフレキシブル回路基板4に生じる応力は低反発層44によって均等化され、フレキシブル回路基板4は長さ方向にわたって均一な内部応力が生じ、円周方向に沿って均一に撓む。フレキシブル回路基板4の一部において顕著な撓みが生じることがなく、レンズ鏡筒の他部品との干渉が防止でき、レンズ鏡筒の小径化が可能になる。
