ABSTRACT:
A vibration damping floor structure for reducing vibrations and shocks applied to a building. The vibration damping floor structure includes a frame structure formed by connecting a plurality of frames, a plurality of ball bearing supports formed on predetermined locations of the frame structure, and a plurality of ball bearings formed on each ball bearing support. Each bearing support is structured so that all of the ball bearings can contact the floor by adjusting the height and following the inclination of the floor.
