Document Type and Number:
Japanese Patent JP2018178653
Kind Code:
A
Abstract:
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
