Vibration isolator and attachment method thereof

A vibration isolator

• comprising a cylindrical bushing main body made of rubber elastomer having a bore through which a bar member passes, and a bracket holding the bushing main body from its outer periphery;
• and adhesive bonded at said bore to said bar member,
• which is characterized in that said bushing main body and said bracket are longitudinally split into two, respectively,
• one pair of resulting split rubber bodies jointly constituting the bushing main body are vulcanization bonded to inner peripheral faces of one pair of resulting half bracket members capable of locking,
• an inside diameter of said bore as molded at both split rubber bodies is made smaller than an outside diameter of the bar member and semicircular peripheral surfaces around the bore of both split rubber bodies are formed to be eccentric on mutually opposite sides thereof;
• both half bracket members are locked together while pinching the bar member by the both split rubber bodies, whereby the both split rubber bodies are compressed so as to enlarge respective inside diameters thereof and said peripheral surfaces around the bore are adhered to an outer peripheral surface of the bar member, and
• the both split rubber bodies are further compressed in mutually opposing directions by locking of the both half bracket members in a butt contacting state.
