Abstract:
1. A vibration damping device, comprising: a first mounting member; a second mounting member having a cylinder portion; a main rubber elastic body elastically connecting the second mounting member and the first mounting member being arranged on one side in an axial direction of the cylinder portion of the second mounting member; a cylindrical outer bracket fit onto the cylinder portion of the second mounting member; and an annular stopper portion formed out of a portion of the outer bracket such that the annular stopper portion is an integral piece of the outer bracket, the annular stopper portion extending around the first mounting member and being defined by a first portion of the stopper portion that extends axially outwardly beyond the second mounting member, a second portion of the stopper portion extending radially inwardly to define a first pressure receiving portion, a bound stopper member that restricts mutually approaching displacement of the first and second mounting members in the axial direction, which is provided by the first pressure receiving portion, a second pressure receiving portion in a cylindrical form defined by a dual structure formed having a radially inner end portion of the first pressure receiving portion extend axially inwardly to form an outer peripheral plate and then folded axially outwardly to form an inner peripheral plate, the outer peripheral plate and the inner peripheral plate extending parallel to each other in the axial direction; and an axis-perpendicular stopper member that restricts relative displacement of the first and second mounting members in the axis-perpendicular direction, which is provided by the second pressure receiving portion.
