Abstract: An anti-vibration rubber device is capable of advantageously preventing cracks from occurring in a constricted portion because of a long time use in a high-temperature environment. A rubber ring having higher resistance to gas permeability than a main rubber portion is externally inserted in a tension-deformed state to a stress concentration portion of a constricted portion in the main rubber portion that connects a first attachment member and a second attachment member. Due to a restoring force from the tension-deformed state, the rubber ring is tightly attached without being bonded to an outer peripheral surface of the stress concentration portion.
