PROBLEM TO BE SOLVED: To enhance the shear fracture strength while suppressing the reduction of equivalent rigidity.SOLUTION: A laminated rubber bearing 1 restricting shear deformation in a first direction X, comprises a laminated body 10 in which rigid sheets 8 and rubber elastic plates 9 are alternately laminated, and protective layers 11 that cover the periphery thereof. The rigid sheets 8 and the rubber elastic plates 9 have the same shape and form rectangular plate shape. At least one of the rubber elastic plates 9 includes end portion rubber parts 20A that are disposed only at both ends of a second direction Y, and main body rubber parts 20B as the remainder thereof, where the end portion rubber parts 20A form with soft rubber compared to the main body rubber parts 20B.SELECTED DRAWING: Figure 3
【課題】 等価剛性の低下を抑えながら剪断破壊強度を高める。【解決手段】 第１方向Ｘの剪断変形が規制された積層ゴム支承１であって、硬質板８とゴム弾性板９とが交互に積層された積層体１０と、その周囲を被覆する保護層１１とを具える。硬質板８とゴム弾性板９とは互いに同形かつ矩形板状をなす。ゴム弾性板９の少なくとも１枚は、第２方向Ｙの両端部のみに配される端部ゴム部２０Ａと、残部である本体ゴム部２０Ｂとからなり、かつ端部ゴム部２０を本体ゴム部２０Ｂよりも軟質のゴムで形成した。【選択図】図３
