ABSTRACT:
A base isolation device for a structure capable of efficiently and effectively suppressing the vibration of a structural body in surface outside direction, wherein a tension member having on overall length longer than an interval between support points provided on the structural body at a specified interval is disposed between the support points, one end parts of first link pieces are rotatably connected midway to the tension member directly or through rigid members, one end parts of second link pieces are rotatably connected to the structural body, the other end parts of the first link pieces are rotatably connected to the other end parts of the second link pieces, and an energizing member providing a tension to the tension member by energizing the first link piece and the second link piece and a damping member operated by the rotation of the first link piece and the second link piece are installed between the structural body forming the structure and connection parts between the first link pieces and the second link pieces.
