PROBLEM TO BE SOLVED: To provide a compact uplift preventing device capable of positively preventing the lift of a base-isolated building from uplifting and having a small grounding area and few binding parts. SOLUTION: A base plate 21A mounted with a first universal joint 22A is mounted to the lower part of an upper skeleton 11 of the base-isolated building 10, and a base plate 21B mounted with a second universal joint 22B is mounted to the upper part of a lower skeleton 12. The respective other end sides of arms 22a, 22b of the first and second universal joints 22A, 22B are mounted in a bent state to a third universal joint 22C provided with a pin of cruciform plane shape so that the extended direction of the arm 22a and the extended direction of the arm 22b form a dog legged shape. The uplift preventing device 20 of such constitution is mounted between laminated rubber 13 provided at the base-isolated building 10. COPYRIGHT: (C)2004,JPO&NCIPI
