RUBBER BEARING BODY, AND RUBBER BEARING DEVICE HAVING THE RUBBER BEARING BODY MOUNTED THEREON
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
【課題】荷重が作用したとき、外周部へゴム層が膨出することを抑制し、小型化、薄型化、耐久性向上を図ることができるゴム支承体とこのゴム支承体が設けられているゴム支承装置を提供する。【解決手段】ゴム支承体２０は、所望の形状に形成され、中間補強板２５をゴム層２３の間に内蔵している積層ゴムと、前記積層ゴム部材の一方の端部に設けられる上補強板２１と、前記積層ゴム部材の他方の端部に設けられる下補強板２２とが一体に形成されているゴム支承体であって、前記中間補強板は、前記積層ゴムの中心部から径方向の所定の範囲内に亘って設けられ、肉厚が所定の厚さに形成された平板状の第１補強部２５ａと、前記第１補強部の外周側に設けられ、前記第１補強部の肉厚より、厚さが厚くなる部位に形成されている第２補強部２５ｂとからなっている。【選択図】図４
