PURPOSE:To reconcile mount durability and stopper performance by connecting an inner tube fitting and an outer tube fitting plus plural intermediate tube fittings with one another through each rubber elastic body, forming a double bush construction, while adopting such a means as installing a stopper fitting additionally in the inner tube fitting and so on. CONSTITUTION:A suspension bush 10 is provided with an inner tube fitting 12, an intermediate tube fitting 14 and an outer tube fitting 16 in order at regular intervals. Then, the inner tube fitting 12 and a first intermediate tube fitting 18 are connected to each other through an inner rubber elastic body 22, while a second intermediate tube fitting 20 and the outer tube fitting 16 are connected as well through an outer rubber elastic body 24. In addition, a buffer rubber layer 44 is additionally installed in a pocket part 34 of the stopper fitting 36. Moreover, a metallic sleeve 30 is installed the inner tube fitting 12, and the first intermediate fitting 18 is clamped to this sleeve 30, thereby closing this pocket part 34, and a pair of fluid chambers 46 being interconnected to each other is formed by an orifice passage 42. |
