Details	The three dimensional (3D) seismic base isolation system for applying to the civil building have been proposed in Part 1. In this paper, test results for confirming mechanical property of the device are reported. The proposed 3D seismic isolation system consists of the 3D seismic isolation device and the rocking suppression device. The 3D seismic isolation device consists of laminated rubber bearings as horizontal isolation devices and air springs as vertical isolation devices. The rocking suppression device consist of oil dampers connected by oil pressure piping in order to control a rocking vibration which becomes easy to be excited because the vertical rigidity of seismic device lowers. To confirm the applicability to a real building to each device, the tests with actual size devices were executed. As the results, the seismic isolation performance of 3D isolation device was confirmed, and the rocking control performance of the rocking suppression device was confirmed.
