PROBLEM TO BE SOLVED: To provide a laminated rubber bearing suitable for a residential building and other relatively lightweight building structures and to provide a laminated rubber bearing smaller with excellent economical efficiency compared with a conventional one as to general building structures and large-sized buildings. SOLUTION: The structural laminated rubber bearing 1 for suppressing the shake of a structure caused by vibrating external force is set so that buckling load N<SB>H</SB>in micro deformation caused by vertical load of laminated rubber and shearing rigidity K<SB>S</SB>of the laminated rubber satisfy the relation of N<SB>H</SB>≤5K<SB>S</SB>/3 to enhance buckling stability in a large deformation region. In the case of using the laminated rubber bearing 1 for the residential building A, the height H of the laminated rubber is preferably set to 10 cm or more, and a diameter or width D is set to 20 cm or less to provide a relatively elongate proportion.
