Zusammenfassung:	Provided is an antivibration rubber device capable of beneficially preventing the occurrence of cracking in a constricted section due to prolonged use in a high-temperature environment. A rubber ring (32) having a gas permeability resistance that is higher than that of a main body rubber section (16) is fitted in a tensile state over a stress-concentrating section (30) of a constricted section (28) provided to the main body rubber section (16) connecting a first mounting member (12) and a second mounting member (14). The rubber ring (32) is configured so as to be in non-adhering close contact with an outer peripheral surface of the stress-concentrating section (30) on the basis of a restoring force from the state of tensile deformation.
