Abstract
A vibration absorption that is both capable of damping vibrations in two directions and high in durability. A pair of pressure receiving chambers (A) and (B) at symmetrical positions sandwiching an axis S are structured between a first rubber elastic body () and a second rubber elastic body (). The shape of a first rubber elastic body () in an unloaded state is determined such that a region between an inner side joining portion (B) and an outer side joining portion (A) becomes substantially horizontal in a loaded state in which the first rubber elastic body () supports the weight of an engine.
