Abstract
A structure comprising a pair of end plates, plural longerons arranged parallel to one another and elastically buckled, a plurality of radial spacers for holding these longerons at a certain interval and a pair of diagonal cords stretched between two adjacent radial spacers, between one of the end plates and the uppermost radial spacer and between the other of the end plates and the lowest radial spacer, respectively, wherein a means is attached to one of the paired diagonal cords stretched between one of the end plates and the uppermost or lowest radial spacer to apply a predetermined tension to this diagonal cord. The transforming of the longerons or radial spacer located at one end of the structure can be restrained by the tension applying means while the structure is being deployed or collapsed.
