PROBLEM TO BE SOLVED: To provide a rubber bearing body that suppresses swelling of a rubber layer toward outer peripheral part when a load is exerted, and may be made more compact, thinner and more durable, and a rubber bearing device having the rubber bearing body mounted thereon.SOLUTION: A rubber bearing body 20 includes laminated rubber formed in a desired form and having a built-in intermediate reinforcing plate 25 between rubber layers 23, an upper reinforcing plate 21 disposed on an end of the laminated rubber member, and a lower reinforcing plate 22 disposed on the other end of the laminated rubber member, the laminated rubber member, the upper reinforcing plate and the lower reinforcing plate being formed integrally. The intermediate reinforcing plate includes a flat plate-form first reinforcing part 25a disposed within a prescribed range from the center of the laminated rubber in a radial direction and having a prescribed wall thickness, and a second reinforcing part 25b disposed on an outer peripheral side of the first reinforcing part, at a portion with a greater wall thickness than the wall thickness of the first reinforcing part.SELECTED DRAWING: Figure 4 |
