を特徴とする内・外筒形防振体。 a connecting elastic material layer 3 extending in the radial direction between the inner cylinder 2 and the outer cylinder 1 and capable of shearing and deforming in response to movement in an eccentric direction intersecting the radial direction; and a pair of buffering elastic material layers 4 which are brought into close contact with the inner surfaces facing each other and which can be compressively deformed in contact with the connecting elastic material layer 3 when the movement in the eccentric direction exceeds a predetermined value. - In the outer cylindrical vibration isolator, at least one of the buffering elastic material layers 4
The connecting elastic material layer 3 is placed near both end sides on the width side of the connecting elastic material layer 3.
An auxiliary elastic material layer 5 protruding toward the bonded end of the outer cylinder 1 is integrally provided to prevent the vicinity of the bonded end of the outer cylinder 1 from buckling when the connecting elastic material layer 3 undergoes shear deformation. An inner/outer cylindrical vibration isolator characterized by being able to prevent vibration through elastic contact.
