。Both the rising wall 4a and the hanging wall 4b are made of steel plates or the like having high rigidity, and are separated from the floor assembly 2 and the slab 1 with a gap, and are arranged, for example, so that one surrounds the other. A viscous material 4C is filled between the walls 4a and 4b, which absorbs horizontal force and vertical vibration during an earthquake by its viscous resistance, and causes the device 4 itself to exhibit viscous damping performance.
