Abstract
Prior art movable types of artificial walls are incapable of offering attractive climbing on irregular wall surfaces, and in the case of a prior art artificial wall having an irregular shape formed on its wall surface, it is difficult to immediately change the irregular shape, and in addition, it is impossible to change the irregular shape while an athletic competition is in progress. A movable artificial wall according to the present invention includes multiple plates each made of a plate of polygonal shape and connected to one another by connection means each of which provides pivotal connection between the sides of the multiple plates, and is characterized in that the whole of each of at least two sides of one of the multiple plates is connected to the whole of one side of another of the multiple plates and the multiple plates are connected to one another so that the multiple plates are closely adjacently arranged about at least one vertex of at least one of the multiple plates.
