LAMINATE RUBBER BEARING BODY
PROBLEM TO BE SOLVED: To provide a laminate rubber bearing body capable of preventing an adhesion portion to plates of upper and lower end parts from being peeled and of reducing concentration of tensile stress or compression stress due to deformation, to obtain a desired durability life by a simple structure.SOLUTION: A laminate rubber bearing body includes: a laminate rubber body in which a plurality of rubber-like elastic plates and a plurality of intermediate hard plates are alternately laminated and connected; and end part hard plates each connected to both upper and lower end surfaces of the laminate rubber body. For the plurality of rubber-like elastic plates, a thickness of an outer peripheral part of at least one rubber-like elastic plate from upper and lower ends of the laminate rubber body toward a center part in a lamination direction is made thicker than a thickness of a body part on a center side with respect to the outer peripheral part.SELECTED DRAWING: Figure 1
【課題】簡易な構成で、上下端部のプレートとの接着部分が剥がれにくく、変形に伴う引っ張り応力や圧縮応力の集中を緩和して、所望の耐久寿命を得ることができる積層ゴム支承体を提供する。【解決手段】複数枚のゴム状弾性板と複数枚の中間硬質板とが交互に積層して接合して形成される積層ゴム体と、前記積層ゴム体の上下両端面に接合される端部硬質板と、を有する。複数枚のゴム状弾性板では、積層ゴムの上下端からそれぞれ積層方向の中央部へむかう少なくとも一枚以上のゴム状弾性板の外周部の厚みを、当該外周部より中心側の本体部の厚みよりも厚くした。【選択図】図１
