Claims

[Claims for Utility Model Registration] 1. A utility model consisting of a casing rigidly attached to a lighting column, a weight suspended within the internal space of the casing, and a spring that elastically supports the weight horizontally from the casing. Features a one-mass vibration damping device for lighting pillars. 2. A casing that is rigidly attached to a lighting column, a weight that is housed within the casing and is tiltable with respect to a vertical axis or can be moved horizontally, and a number of plates interposed between the outer periphery of the weight and the casing. A one-mass vibration damping device for lighting poles consisting of a spring and a spring. 3. A storage container having a wall made of a rigid-elastic material, a horizontally movable rigid-elastic weight body housed within the container so as to be able to collide with the wall with a gap between the container and the wall, and the container. A one-mass vibration damping device for a lighting column, consisting of a connecting part that rigidly connects the lighting column to the lighting column.
