    Abstract: PURPOSE:To obtain an extremely high attenuation damper exhibiting a good damping effect by using the high attenuation characteristic (high hysteresis loss) of a slightly bridged rubber which is extremely low in a bridging characteristic. CONSTITUTION:A slightly bridged rubber constituting a damper 8 is provided with material characteristic in which hystresis ration (h50) at the time of deformation under tension by 50% at 25 deg.C is above 0.25 by mixing a bridging agent of 1 to 70% by weight of the minimum amount of the mixture of the bridging agent to be mixed to a rubber material. Such a damper 8 may be formed in such a manner that non-bridged rubber is dispersed in the slightly bridged rubber or the non-bridged rubber c is filled in the slightly bridged rubber a as respectively independent structures. Accordingly, an excellent damper provided with high hystresis under the non-bridged state of the rubber and excellent mechanical property under a bridged state is provided.
