<P>PROBLEM TO BE SOLVED: To prevent a support device comprising a laminated rubber and a stopper member from being damaged due to a shock at collision of the laminated rubber to the stopper when earthquake motion larger than designed earthquake motion is applied, and to prevent an article installed in a building from being damaged due to a large shock applied to the building at the collision. <P>SOLUTION: The support device includes the laminated rubber 3 and the stopper member 4 therefor, a lower end of the stopper member 4 is in contact with a lower end of the laminated rubber 3, a support surface 5 of the stopper member 4 facing the laminated rubber 3 is separated from the laminated rubber 3 from the lower end toward the upper end and has a convex shape on a side of the laminated rubber 3 when viewed in a vertical cross section, and thus even if earthquake motion larger than the deigned earthquake motion is applied, the laminated rubber 3 makes facial contact with a convex support surface 5b on the upper side of the support surface 5 while gradually increasing the horizontal rigidity, so that impact force at collision of the laminated rubber 3 to the stopper member 4 is alleviated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
