A method disclosed by Japanese Patent Laid-Open No. 3-2407 is known. In the case of this method, a metal locking member that extends in the width direction of the upper structure and protrudes upward is integrally provided at the end of the metal base plate in the extension and contraction direction of the upper structure, and the through hole of the locking member is provided. The one end portion of the towing screw rod inserted in the base plate is screwed into the female screw hole of the lower metal plate in the rubber bearing placed on the base plate, and one end face of the annular spacer fitted into the towing screw rod is attached to the locking member. Of the center hole jack that is engaged with the side surface of the pulling rod and the base end face of the cylinder of the jack in the jack is engaged with the other end face of the annular spacer, and the female screw member screwed to the other end side of the pulling rod is inserted into the center hole. After engaging the end of the hollow piston rod in the jack and hardening the concrete of the concrete superstructure constructed on the upper part of the rubber bearing, the center hole jack is used to pull the screw. The lower metal plate in the rubber bearing is moved in the direction of contraction of the upper structure through the pre-shearing, the rubber layer in the rubber bearing is pre-shear-deformed, and then the center hole jack, the pulling rod and the annular spacer are removed. .

という欠点がある。In the case of the pre-shear deformation pre-installation method of the conventional rubber bearing described above, since the locking member largely projects upward from the base plate, the weight of the base plate with the locking member becomes large and the manufacturing cost is high. However, since there is a large amount of upward protrusion of the locking member, the external appearance is poor.
