PROBLEM TO BE SOLVED: To provide an extensible and expandable structure using a tape spring.SOLUTION: An expandable structure 50 includes a fitting base including a first point 12, and a second point 13 and a third point 14 of the opposite side, a storage reel rotatable around an axis Z, and a tape spring 16 switchable from the configuration of being wound around the axis Z of the storage reel to the configuration of being expanded along an axis X substantially vertical to the axis Z, the first and second points 12 and 13 forming a double support with the tape spring to maintain the tape spring in the expanded configuration. The third point 14 can form a simple support with the tape spring 16, the storage reel can move with respect to the third point 14, and the storage reel is pressed to the third point 14 to guide expansion of the tape spring 16.SELECTED DRAWING: Figure 8 |
