Abstract
The vibration isolation is a technology that lowers the natural frequency of the system and lowers the transmission rate of the object's vibration. The vibration isolation and seismic isolation are the similar technologies. However, the vibration that seismic isolation targets are only an earthquake. The device for seismic isolation is a seismic isolator. Seismic isolators are classified into three kinds "laminated rubber bearing", "sliding bearing", and "roller bearing". Recently, laminated rubber bearings might be applied for the skyscraper building. Accumulating laminated rubber bearing breaks when strongly pulled. However, laminated rubber bearing used for the skyscraper building is pulled at the earthquake. Here, it explained the mechanism because of not breaking the laminated rubber bearing.
