PURPOSE:To improve the durability of a vibration-proofing device by providing, between inner and outer tubes, a stopper body pressed in from both end parts in the axis direction of the inner and outer tubes. CONSTITUTION:Bulge of a diaphragm rubber 34 is not restricted by the restriction plate part 30 of a stopper body 26 in normal time. When a large load acts on an inner tube 12, however, since both end parts of the inner tube 12 abuts the edge part of the through hole 27 of the stopper body 26 even if the inner tube 12 moves so as to approach an outer tube 16, further approach of the inner tube 12 to be outer tube 16 is prevented, and strong abutting of the rubber 34 to the inner tube 12 is eliminated. Moreover, since the limit plate part 30 of the stopper body 26 is arranged in the inner tube 12 side of the rubber 34, bulge of the rubber 34 is limitted and protected also by the limit plate part 30. As a result, excessive bulge of the diaphragm rubber 34 can be eliminated, bursting of the rubber 34 is prevented, and durability of a vibration-proofing device 10 can be improved. |
