PROBLEM TO BE SOLVED: To provide a vibration damper having an excellent shock resisting strength that prevents reinforcements from excessive deformations and reinforcements or structure itself from damages due to vibration energy, and applicable to even areas where relative distances between structural materials can largely vary. SOLUTION: This is a vibration damper with both ends to be fixed to structural members having variable relative distances between them, and is provided with a tube containing an axially extendable space and a fixing seat at both ends to define the space, a first side end member having the one end fixed to the fixing seat at the one end of the tube and the other end fixed to one structural material, a second side end member having the one end movably penetrating a fixing seat at the other end of the tube and extending through the space and the other end fixed to the other structural material, a movable seat fixed to the one end located within the space of the second side end member, and an elastic member disposed between the movable seat and the fixing seat within the space.
