To correspond only to a dynamic load of a structure to show vibration damping function, to change specifications of a damper without changing jack-up of the structure or a level of the structure, to decrease a cross section of a rod in which a spring is disposed at a rod outer peripheral side to reduce a weight, to function as a mechanical stopper, and to enable initial load setting of a spring or spring adjustment.SOLUTION: In a device installed between a structure a and a foundation b, a cylindrical body 2 is vertically provided, and a rod 3 is vertically disposed in the cylindrical body. End bodies 21 and 22 are attached to both ends of the cylindrical body 2, a center partition body 23 is provided at an inner center of the cylindrical body 2. A rod insertion hole 21b is formed at a lower end body 21, a rod insertion 22b is formed at an upper end body 22, and a rod insertion hole 23a is formed at a center partition body 23. Stoppers 31 and 32 are attached to both upper and lower sides of the rod 3, and one of them is attached to the rod 3 so as to move forward/backward, and a pair of springs 4 is attached at a rod outer peripheral side 3a in the cylindrical body 2.SELECTED DRAWING: Figure 1
