Abstract
Provided are a tubular vibration-damping device for a vibration-damping connecting rod, a vibration-damping connecting rod using the same and a method of manufacturing the vibration-damping connecting rod. The device including an inner shaft member and an outer tubular member being connected by a main rubber elastic body, the inner shaft member having a structure wherein first and second connecting members are inserted into a sleeve member bonded to the main rubber elastic body, the connecting members being axially overlapped with and spaced from each other to provide a rod-end insertion space communicated with outside via rod insertion holes that open through peripheral walls of the sleeve member and the outer tubular member, one end of a rod main body being inserted via the rod insertion holes into the rod-end insertion space and fixed to the first and second connecting members by a fastening member.
