に関するものである。Description: TECHNICAL FIELD The present invention relates to a laminated structure, and more particularly to a laminated structure suitable for use in a vibration isolation device, a vibration isolator, a vibration damping device, a vibration isolation device, and the like. It is a thing.
［従来の技術］ 複数個の鋼板等の剛性を有した硬質板と、粘弾塑性的性

いる。[Prior Art] A composite laminate obtained by alternately laminating a plurality of rigid hard plates such as steel plates and a soft plate such as rubber having viscoelastic-plastic properties is a rubber for a vibration isolator. Widely used as a support piece.

形成したゴム支承片が開示されている。In such a laminated structure, when it is subjected to compression or shear deformation, the peripheral portion of the soft plate is subject to large local strain, and deterioration is more likely to proceed than in the inner portion. In order to deal with this, Japanese Patent Publication No. 58-30818 discloses a rubber support piece in which a peripheral surface of a steel plate is formed with an inclined surface and a side surface of a rubber elastic body is formed with a concave curved surface.

材に具備させることができないとう問題があった。[Problems to be Solved by the Invention] Conventionally, it has been known that when the laminated structure is subjected to compression or shear deformation, the peripheral edge of the soft plate is subjected to large local strain.
It was not always clear how deep the effect was in the center, and when the soft material was a rubber material, it was difficult to match the vulcanization conditions of different soft materials, and Due to the cumbersomeness of, soft plates have been manufactured to form a whole layer of one type of soft material. Therefore, although it is possible to reduce the local strain applied to the peripheral portion of the soft plate as in Japanese Patent Publication No. 58-30818, for example, when a soft material having excellent ozone resistance is used, the laminated materials are laminated. There are problems that the flexural durability of the structure becomes poor, and that when natural rubber or the like having excellent flexural durability is used as a soft material, ozone cracks cannot be avoided. Similarly, there is a problem that the soft material cannot be provided with contradictory properties such as high damping property and low creep property, low thermal conductivity and vulcanization stability.

A soft plate that has properties that are difficult to develop with the same material, such as a soft plate made of the same material, or an inner part made of a material with excellent durability and a peripheral part made of a material with excellent weather resistance.
