摘要
In the case of an earthquake that exceeds the physical displacement width of the driving unit, the ball is separated from the earthquake isolation driving unit for a general ball control ring. At this time, the object to be protected does not fall due to the sliding action of the upper plate and the lower plate in the absence of a ball, but after an earthquake, the upper plate and the lower plate are stopped in a cross-over state. That is, the inconvenience of being in the original position occurs. Also, preparation for aftershocks may be relatively late. In the present invention, a ball separation prevention mechanism was developed and attached to the upper surface of the lower plate of the rolling part, thereby fundamentally preventing the ball from being separated.
