DETAILED DESCRIPTION This invention is made in view of the above-mentioned problems, and the purpose of the invention is to present an aseismatic mount for exhibition of articles and a showcase equipped with the aseismatic mount, in which the exhibition articles on the mount or the showcase itself and/or the exhibition articles contained therein are prevented from collapsing by disminishing a large horizontal shake without fail even in case of a great earthquake while making it easy to restore to the original position after the earthquake, and the outward appearance of the aseismatic mount and the showcase goes well with the surroundings while maintenance and inspection are easy to conduct.
To achieve the above object, the aseismatic mount for exhibition of articles such as artwork according to the present invention comprises, a lower mount frame, a middle mount frame, an upper mount frame for mounting exhibition articles thereon, aseismatic means having rollers integrally an axis of each of which rollers is shifted eccentrically with respect to one another in up and down directions, said aseismatic means being interposed between the lower mount frame and the middle mount frame at plural positions, so as to roll one of said rollers, which has the axis shifted eccentrically in an upward direction, in contact with the lower mount frame, and to roll the other roller, which has the axis shifted eccentrically in a downward direction, in contact with the middle mount frame, and further aseismatic means having the same construction as the said aseismatic means, said further aseismatic means being interposed between the middle mount frame and the upper mount frame at plural positions in such a way that the rolling directions of the rollers cross the said aseismatic means, so as to roll one of said rollers, which has the axis shifted eccentrically upwardly, in contact with the middle mount frame, and to roll the other roller, which has the axis shifted eccentrically downwardly, in contact with the upper mount frame
