Abstract
The utility model provides a damping device which minimizes the number of components and inhibits projections in anterior -posterior directions of an installation part of a second plate member clamping a first plate member from two sides thereof to small extent. A base end side of a first plate is installed on one side which performs relative displacement motions, and a pair of base end sides of second plates is installed on another side. The paired base end sides of the second plate members clamp the first plate member from two sides. Viscoelastic bodies are filled between the first plate member and one second plate member and between the first plate member and another second plate member. The relative displacement motions of one side and another side are attenuated through shear deformation of the viscoelastic bodies. The paired second base end sides of the second plates are constituted by a plate portion and a cut portion which are parallel in the direction of width. The base end side of one second plate member and the base end side of another second plate member are installed on another side in the same plane through engagement between the plate portion and the cut portion. A pair of base end side plates of the second plate members forms a contracting neck which is formed as a buffering part.
