In an extensible structure comprising more than one elastic longitudinal beam, the structure is reduced by elastically deforming each longitudinal beam into a coil shape, and is sequentially extended into a columnar shape from one end by restoring each longitudinal beam. A spring member for raising the vertical beam that pulls the vertical beam deformed into a coil shape in the rising direction is installed between the extension start end side of the vertical beam and the end plate to which the vertical beam end on the extension start end side is pivotally connected. and the spring member is connected to the longitudinal beam at a position an appropriate distance from the pivot end of the end plate of the longitudinal beam.
