PROBLEM TO BE SOLVED: To provide a rubber bearing body that hardly causes an ozone crack on a rubber surface of a laminate.SOLUTION: A rubber bearing body includes an upper shoe 7 that is fixed to an upper end surface of a laminate 2 in which a steel plate 3 and a rubber layer 4 are stacked, and a lower shoe 8 that is fixed to a lower end surface of the laminate 2. A groove 9 is formed in at least a range on the side of a bridge axis direction X, in a position corresponding to corner parts of end steel plates 5 and 6 in a longitudinal-section view of a rubber surface of the laminate 2 of the rubber bearing body 1 made of the end steel plates 5 and 6 thicker than the steel plate 3, on at least one of the upper and lower end surfaces of the laminate 2.
【課題】積層体のゴム表面にオゾンクラックが発生し難くしたゴム支承体を提供する。【解決手段】鋼板３とゴム層４とを積層した積層体２の上端面に固定される上沓７と、積層体２の下端面に固定される下沓８とを備えて、積層体２の上端面と下端面の少なくとも一方が、鋼板３よりも厚い端部鋼板５、６で構成されるゴム支承体１の積層体２のゴム表面の縦断面視で端部鋼板５、６の角部に相当する位置で、少なくとも橋軸方向Ｘ側の範囲に溝９を形成する。【選択図】図３
