ABSTRACT:
In a vibro-isolating joint including two rigid flanges, a flexible cylindrical member such as bellows interposed between the flanges and a plurality of limiting bolts extended through opposed through holes in the flanges, a cylindrical elastomer body is retained in each of through holes in at least one of the flanges and a hollow sleeve is concentrically integrated with the elastomer body so as to protrude one end of the hollow sleeve from an outer surface of the flange so that lock nuts on the limiting bolts engage the protruded ends of the hollow sleeves resiliently supported in the through holes, respectively to thereby provide a high axial thrust together with a vibration isolating property.
