The present invention provides a vibration damper comprising: a cylindrical body (1); a core member (2) disposed on one side of the cylindrical body (1) on the central axis thereof to be coaxial with the cylindrical body (1); and a main rubber body (3) for connecting an inner peripheral surface of the cylindrical body (1) over the entire circumference thereof to the core member (2), wherein an outer surface of the main rubber body (3) is formed to have a truncated cone-like shape protruding toward the core member (2) in a vertical cross section including the central axis of the main rubber body, the vibration damper is adapted to absorb, primarily by shearing deformation of the main rubber body (3), vibrations inputted in the central axis direction from a member on the vibration-generation side, so that the inputted vibrations are prevented from being transmitted to a member on the vibration-transmission side, and the main rubber body (3) is constituted of two types of rubber elastic bodies (3a, 3b) having different rubber hardness values and firmly and integrally attached to each other over the circumference of the cylindrical body (1). |
