To provide an extendable arm structure having a high use value in various applications of the industry.SOLUTION: An extendable arm structure (10) includes: an upper extendable arm (11) and a lower extendable arm (12) which extend in the same direction at a parallel interval; and vertical connection members that connect the upper and lower extendable arms. Each of the extendable arms (11, 12) includes a plurality of X-shaped cross units each formed by pivotally connecting two rigid members (11a, 11b, 12a, 12b) via middle connection shafts (11c, 12c), and two end connection shafts (11d, 12d) that pivotally connect ends of adjacent ones of the cross units. The extendable arm structure (10) further includes a planar member (13) that closes, in a planar manner, a space between the rigid members (11a, 11b) of the upper extendable arm and the rigid members (12a, 12b) of the lower extendable arm which extends parallel to the rigid member of the upper extendable arm in the same direction.SELECTED DRAWING: Figure 1
【課題】産業界の種々の用途において利用価値の高い伸縮アーム構造体を提供する。【解決手段】伸縮アーム構造体（１０）は、平行な間隔で同方向に延びる上部伸縮アーム（１１）および下部伸縮アーム（１２）と、上下の伸縮アームを連結する縦方向連結部材とを備える。各伸縮アーム（１１，１２）は、中央連結軸（１１ｃ，１２ｃ）を介して２個の剛性部材（１１ａ，１１ｂ，１２ａ，１２ｂ）を回動可能に連結した複数個のＸ字状のクロスユニットと、隣接するクロスユニットの端部同士を回動可能に連結する２個の端部連結軸（１１ｄ，１２ｄ）とを含む。伸縮アーム構造体（１０）は、さらに上部伸縮アームの剛性部材（１１ａ，１１ｂ）と、平行な関係で同方向に延びる下部伸縮アームの剛性部材（１２ａ，１２ｂ）との間の空間を面状に閉塞する面状部材（１３）を備える。【選択図】図１
