To provide a retractable extension boom which can prevent jump phenomenon in a storage process, and can prevent torsional deformation and lateral buckling of a convex panel.SOLUTION: Respective convex panels P1, P2 to P10 are coupled by a thermoplastic polymeric film F. A fixed terminal C1s, C1s' of a storage cable C1, C1'is fixed to a pantograph structure on a tip side of a magic hand structure MH1, MH1'. The magic hand structure MH1 is provided on a right side of the convex panels P1, P2 to P10, and the magic hand structure MH1' is provided on a left side of the convex panels P1, P2 to P10. That is, the magic hand structures MH1, MH1' are so provided as to sandwich the convex panels P1, P2 to P10.SELECTED DRAWING: Figure 5

    【課題】収納過程における飛び移り現象を抑止でき、コンベックスパネルの捩れ変形及び横倒れ座屈を防止できる可収納型伸展ブームを提供する。【解決手段】各コンベックスパネルP1、P2、…、P10間は熱可塑性高分子フィルムFによって結合する。収納用ケーブルC1、C1’の固定始端C1s、C1s’はマジックハンド構造MH1、MH1’の先端側のパンタグラフ構造に固定される。マジックハンド構造MH1はコンベックスパネルP1、P2、…、P10の右側になるように設けられ、マジックハンド構造MH1’はコンベックスパネルP1、P2、…、P10の左側になるように設けられ、つまり、マジックハンド構造MH1、MH1’はコンベックスパネルP1、P2、…、P10を挟むように設けられる。【選択図】 図5
