PROBLEM TO BE SOLVED: To prevent shearing of a rubber layer even by a high load from an upper part without activating unreasonable shearing stress of a horizontal direction at the time of the earthquake on a load supporting member by slidably supporting an upper structure by the load supporting member and the like for high supporting pressure. SOLUTION: In an elastic support device for a structure arranged between an upper structure 1 and a lower structure 2, either one of steel plate 9 in steel plates 9, 10 in an elastic support body 5 provided with the steel plates 9, 10 vertically is nonmoveably locked with either one of structures in the upper structure 1 or the lower structure 2 directly or indirectly, the other steel plate 10 in the elastic support body 5 is directly or indirectly locked with the locked structure side movably in a vertical direction and nonmovably in a lateral direction, the outer side of the other steel plate 10 is formed as a surface for supporting the upper structure 1 or the lower structure 2 of a non-locking condition freely to slide at all times. An interface sucked with an elastic layer 6 in each steel plate 9, 10 of the elastic support body 5 is formed as a rough surface so as to enlarge a sticking surface, and increase shearing resistance force of the rubber layer. |
