PURPOSE: To solve that stress is accumulated on a supporting base so as to provide the bearing which is suitably to using at a high temperature by providing a lever base means for regulating expansion in a load direction of an elastomer layer according to heating between the elastomeric layer and at least one side of two members. CONSTITUTION: In this elastomer bearing, a stiffness casing 31 such as metal is provided with a front wall 32, a rear wall 33, and upper and lower supporting member walls 34, 35. An inside structure laminating body 36 provided with an inside metallic member 37, a plurality of elastomer layers 38, 39, and metallic supporting plates 40, 41 is held by the casing 31. In this case, at least one part of outermost surfaces in the upper and lower metallic supporting plates 40, 41 is covered so as to form a plurality of recessed surfaces 42, 43. A pair of upper and lower lever bases 46a, 46b, 47a, 47b are formed by each of recessed surfaces 42, 43. Comparatively small clearances 44, 45 are formed on each of metallic supporting plates 40, 41 so as to deflect in directions of the upper and lower supporting member walls 34, 35 by thermal expansion of each of elastomeric layers 38, 39. |
