Abstract
An anti-vibration rubber composition contains: a polymer comprising component (A); and components (B) to (E). The mixing ratio of the components (B) and (C) is in a range of (B)/(C)=99/1 to 96/4 in weight ratio. As a result, it becomes possible to achieve a low dynamic magnification and to achieve both durability and weather resistance at a high level.
