PROBLEM TO BE SOLVED: To provide a support improved in bonding durability between a recess and an elastic body at an interface by suppressing tensile force generated to the interface of the recess and elastic body when shearing force is generated. SOLUTION: A sliding rubber support 10 disposed on a bridge pier 12 to support a bridge girder 14 comprises a laminated body 16 with a rubber layer 26 and an inner steel plate 28 laminated between an upper connecting steel plate 22 and a lower connecting steel plate 24; a recess 30 provided at the upper face edge part of the upper connecting steel plate 22; outer skin rubber 18 filled in the recess 30 while covering the whole side face of the laminated body 16; and a reinforcing steel plate 20 provided on the upper connecting steel plate 22 and holding and compressing the outer skin rubber 18 between itself and the recess 30. Tensile force generated to the interface of the recess 30 and outer skin rubber 18 when shearing force is generated, is thereby suppressed to improve bonding durability between the recess 30 and outer skin rubber 18 at the interface.
