PROBLEM TO BE SOLVED: To improve vibration absorbing performance and facilitate manufacture by providing a vibration absorbing body constituted out of silicone gel in a hollow vessel having opening parts on both ends. SOLUTION: This damper is constructed so that a vibration absorbing body 3 constituted out of silicone gel is provided in a hollow vessel 5 having an upper opening end part 51 and a lower opening end part 52 on both ends. In this case, a load 8 can be transmitted to the nearly center part of the vibration absorbing body 3 through a vibration shaft 6 and a load plate 7, and vibration loaded by the load 8 is absorbed by the vibration absorbing body 3. Further, a ring-like assistant member 9 is provided on the lower opening end 52 of the hollow vessel 5 so that the vibration absorbing body 3 can be deformed downward projectingly, and a coil spring 2 is provided on the outer circumference of the hollow vessel 5. The silicone gel to be used is favorable to be 10<5> -10<7> dyne/ cm<2> in dynamic storage elastic modulus E' and 0.3-1.0 in dynamic viscoelasticity tanδ. |
