Various vibration attenuation methods such as a base isolation and a vibration control are suggested as seismic safety technique for large scale architectural and civil structure, and these methods have been practical used now. In recent years, these vibration reduction technologies begin to be applied to a small-scale structure. Application of seismic safety technology for a small-scale structure, however, is still remained a lot of developmental element yet. The enormous damage of overturning has been occurred in recent huge earthquakes including Great East Japan Earthquake. Therefore, the countermeasure technique should be an urgent task for huge earthquakes which are expected the occurrence in near future. In this study, a vibration attenuation system for light-weight structure with simple mechanism, good performance and low construction cost. This paper describes the fundamental design index of the overturning prevention mechanism for vending machine with a friction sliding from preliminary seismic response analysis, and new type simple mechanism using rotational support satisfied the specifications is examined from experimental and analytical verification.
