PROBLEM TO BE SOLVED: To provide an inexpensive compact support device allowing a hard spherical body to roll smoothly when an earthquake occurs, and provided with vibration absorbing performance and a function as a foundation packing member. SOLUTION: This rolling support device 1 is provided with upper and lower hard plates 4, 5, a cylindrical positioning member 3 arranged between the upper and lower hard plates 4 and 5, and the hard spherical body 2 inscribing in the positioning member 3 and positioned in central parts of the upper and lower hard plates 4, 5. This device is arranged between an upper structure and a lower structure of a structure to support the upper structure of the structure. The positioning member 3 is bonded to either of the upper and lower hard plates 4, 5, and its outer peripheral side is bonded and its inner peripheral side is not bonded. COPYRIGHT: (C)2004,JPO&NCIPI
