PROBLEM TO BE SOLVED: To prevent commodities housed in an automatic storage from earthquake by providing supporting legs whose upper or lower ends are fixed to a stationary floor or a slidable floor and another ends are abutted slidably to the stationary floor of the slidable floor. SOLUTION: On a floor 2 of a structure 1 an inner structure 5 is placed with several supporting legs thereunder as required so that the inner structure 5 can be slid horizontally with respect to the structure 1, and a slidable floor 16 of the inner structure 5 is placed on the stationary floor 2 with several resilient members 40 thereunder. Top surface of supporting legs 49 are abutting slidably to the stationary floor 2. Since the movable floor of automatic warehouse is horizontally slidable with respect to the stationary floor 2, in case of earthquake, the horizontal vibration will not be transmitted to the automatic warehouse, thereby, commodities storaged in the automatic warehouse will be preveted from earthquake. |
