PROBLEM TO BE SOLVED: To provide an aquarium facilitating the assembly.SOLUTION: The aquarium 1 includes a bottom plate 2 having a polygonal shape in the plane view, a plurality of transparent side plates 3 put on each side edge part of the bottom plate 2 and a plurality of props 4 arranged at each corner part of the bottom plate 2. The prop 4 is obtained by integrally forming a pillar part 4a for holding both side edges 3a and 3a of mutually neighboring two side plates 3 and 3, and a pedestal part 4g having a receiving face 4h for receiving the bottom plate 2 from the lower side. A fitting protruded part 2d in a downward protruded shape is formed at each corner part of the lower face 2g of the bottom plate 2. A fitting recessed part 4i opened upward is formed at the receiving face 4h of the pedestal part 4g of the prop 4. The fitting protruded part 2d is fitted in the fitting recessed part 4i, and the corner part of the lower face 2g of the bottom plate 2 is put on the receiving face 4h of the pedestal part 4g so as to make contact therewith.COPYRIGHT: (C)2010,JPO&INPIT【課題】容易に組立を行うことができる水槽を提供すること。【解決手段】水槽1は、平面視多角形状の底板2と、底板2の各辺縁部上に載置された複数の透明な側板3と、底板2の各コーナー部に配置された複数の支柱4と、を備える。支柱4は、互いに隣接する2つの側板3、3の両側端部3a、3aを保持する柱部4aと、底板2を下方から受ける受け面4hを有する台座部4gとが一体形成されたものである。底板2の下面2gの各コーナー部には下方突出状の嵌合凸部2dが設けられている。支柱4の台座部4gの受け面4hには上方に開口した嵌合凹部4iが設けられている。そして、嵌合凸部2dが嵌合凹部4iに嵌合されるとともに底板2の下面2gのコーナー部が台座部4gの受け面4h上に当接して載置されている。【選択図】図7
