PROBLEM TO BE SOLVED: To reduce the deviation of reaction by the deflection angle of a bridge girder and the fluctuation and deviation of reaction according to the manufacture error of the bridge girder in a slide bearing for supporting the bridge girder extrusively erected from under and sliding the bridge girder on the upper surface, and to safely and surely extrusively move the bridge girder. SOLUTION: A lower shoe 1 having a side arresting part 12 raised over the whole periphery of a steel sheet 11 is placed on a foundation structure or erected structure, and a plurality of divided bearing rubber plates 2 is arranged thereon. An upper shoe 3 having a flat bottom surface is placed on this, and the horizontal movement of the upper shoe 3 is arrested by the side arresting part 12. The upper surface of the upper shoe is flatly finished, a stainless steel plate is adhered thereto, and a bridge girder is supported thereon through a slide plate. The rubber plate 2 is deformed by the placing of a load thereon, and filled in the space enclosed by the upper shoe 3, the lower shoe 1, and the side arresting part 12, when a prescribed load is placed thereon, to support a large load without causing a compression breakage.
