2. Description of the Related Art In recent years, the efficiency of physical distribution systems has been remarkably improved.
In particular, various items are placed together on a pallet that is standardized to a predetermined size and has an insertion port for mechanical loading,
Frequent transportation and storage are carried out. Therefore, in order to temporarily store the articles stacked on the pallet, a rack warehouse in which racks corresponding to the pallet size are three-dimensionally arranged is widely used.

In such a rack warehouse, in order to store as many pallets as possible so that they can be taken in and out, a rack structure is formed by connecting racks in the height direction and extending laterally adjacent to each other to secure a pallet transport path. After that, they are densely arranged side by side in the warehouse building. Further, although such a rack structure supports the vertical load of the pallet, it is usually not provided with a pallet fixing mechanism in the horizontal direction in order to allow the pallet to be taken in and out.

Therefore, when the rack structure shakes in a horizontal direction due to an earthquake or the like, lateral vibrations are also excited in the pallet, causing a load collapse, which may damage stored items loaded on the pallet. . Conventionally, as a countermeasure against this, a beam member is passed between the rack structures and fixed to each other to increase the horizontal rigidity. Moreover, as a vibration control device, a vibration control brace using ultra-low yield point steel or the like, a panel damper, and a column base lifting damper were sometimes provided.

However, it has been relatively recent that a rack warehouse incorporating the above-described vibration control device has appeared. In the past, most expensive items and dangerous goods were never stored on pallets, and even if a large earthquake should occur, it was said that some collapse of cargo was unavoidable. There were many rack warehouses that did not have. However, today, even expensive goods and dangerous goods, which are very dangerous and dangerous when a load collapses,
It is strongly desired that the materials be stored in a rack warehouse. Therefore, we installed vibration control means in such existing rack warehouses,
There is an urgent need for earthquake resistance. However,
There is a problem that it is difficult to install the above-mentioned seismic resistance device because there are restrictions such as the restriction by the Building Standards Law and the fact that it can be installed while using the warehouse when modifying the existing rack structure. It was
