Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an extension structure of which shape change can be attained under application of shape memory resin.SOLUTION: This invention relates to an extension structure in which there is provided a mast main body having a hollow section structure, the mast main body has some folding portions for axially folding the hollow section and capable of attaining an extended state where the folding portions are developed to make a cylindrical structure and a storing state where the folding portions are folded to attain a flat section. The mast main body is divided into several pattern pieces partitioned at the folding portions and each of the pattern pieces is connected by a connecting member having shape memory resin at the folding portions. 【課題】形状記憶樹脂を用いることにより形状変化が可能な伸展構造物を提供する。【解決手段】中空断面構造のマスト本体を備え、マスト本体が中空断面を軸方向に折り畳むための折り目部を有し、折り目部を展開して筒状構造とする伸展形態と、折り目部を折り畳んで扁平断面とする収納形態と、をとることが可能な伸展構造物において、マスト本体は、前記折り目部によって区分される複数のパターン片に分かれ、各パターン片が、折り目部にて形状記憶樹脂を備える連結材にて接合されていることを特徴とする。【選択図】図１
