Recently, earthquakes frequently occur in Japan. In order to protect people from earthquakes, it is necessary to promote seismic isolation devices. The penetration of the devices is late in attached houses, because the devices are very expensive. We must develop a low-cost seismic isolation device for detached houses. We suggested a new seismic isolation device which uses a two-layer circular tube. If the inner layer contacts with the outer layer under lateral compression load, hysteresis is produced in the tube. We think that the tube can have energy absorbing capacity. It is known from previous studies that hysteresis occurs in the tube using by experiments. However, the tubes used in the device are referred to as either clearance fit tubes or interference fit tubes in the process of manufacturing. In this paper, we have clarified a relation between the fit and hysteresis loss using by experiments. As a result, hysteresis loss changes depending on the fit. Hysteresis loss of the interference fit tube is larger than the clearance fit tube.
