<p>PURPOSE:To enhance a vibration damping effect, by forming insertion holes in the axial direction of a rubber bush while accepting rubber stoppers by the cooperative action of swollen parts, protrusively provided in one insertion hole arranged part of an outer cylinder or an inner cylinder, and a spacer fitted and inserted into the insertion holes. CONSTITUTION:An elastic coupling 11 adhesively mounts by vulcanization a rubber bush 14 between an outer cylinder 12 and an inner cylinder 13. The elastic coupling, equally arranging a plurality of insertion holes 15 in the axial direction in the peripheral direction of the rubber bush 14, protrusively provices swollen parts 16 over the whole axial direction of the outer cylinder 12 from an insertion hole arranged part of the outer cylinder 12 toward inside the insertion hole 15. And the coupling, adhesively mounting by vulcanization rubber stoppers 17 in inside surfaces of the insertion holes 15 of the swollen parts 16, is constituted so that a spacer 18, consisting of material of higher rigidity than the rubber stopper 17, cooperates with the swollen parts 16 accepting the rubber stoppers 17.</p> |
