PROBLEM TO BE SOLVED: To reduce the number of components, adjust bridge axial displacement of a rubber bearing body with simple work by only screw adjustment, remove a temporary fixture by only loosening a bolt, remain in an adjusting state and to permit the common utilization of a temporary fixed jig. SOLUTION: A rubber elastic body 6 is provided between a lower shoe fixed to a pier 1 and an upper shoe 5 fixed to a bridge girder, and inclined slide surfaces 17 and 16 opposed to each other at a specific interval in the direction of the bridge axis are provided to the upper shoe 5 and lower shoe 4. A slope member 18 having a through-hole between the slide surfaces 16 and 17 is provided in a vertically slidable manner, and the bridge axial elastic displacement of the elastic body 6 is adjusted by screwing degree of a bolt 19 inserted into the through-hole and a female screw member 20. |
