PURPOSE: To improve durability of an antivibration device without deteriorating durability of a diaphragm by pressing a projection formed on a diaphragm projected toward an outer cylinder side, moving the diaphragm inward, and thereby regulating deformation of the diaphragm. CONSTITUTION: A diaphragm 26 which composes a part of a partition wall of a sub-liquid chamber 38 integrated with an elastic body 16 has a stopper projection 40 projected toward an outer cylindrical fitting 18. In assembling an antivibration device, the stopper projection 40 is in contact with the outer cylindrical fitting 18 and thereby pressed to the side of an inner cylindrical fitting 14. The diaphragm 26 is moved to the side of the inner cylindrical fitting 14. Since the diaphragm 26 is integrated with an elastic body 16, a manufacturing cost of the antivibration device 10 is reduced. Deformation of the diaphragm 26 is regulated in a vertical, that is, extension/contraction direction of the diaphragm 26 by the stopper projection 40 and the inner cylindrical fitting 14. |
