Abstract:

A vibration damping device including a main rubber elastic body elastically connecting a second mounting member and a first mounting member being arranged on axially one side of the second mounting member and a cylindrical outer bracket fit onto the second mounting member. A stopper portion integrally formed with the outer bracket extends radially inwardly to provide a first pressure receiving portion. A bound stopper member that restricts mutually approaching displacement of the two mounting members in the axial direction is constituted by including the first pressure receiving portion. A cylindrical second pressure receiving portion in a dual structure is formed by having the first pressure receiving portion extend axially inwardly and then folded axially outwardly. An axis perpendicular stopper member that restricts relative displacement of the two mounting members in the axis perpendicular direction is constituted by including the second pressure receiving portion.
