PURPOSE:To improve durability of a vibration-proofing device by preventing occurrence of any damage in a diaphragm through a process of smoothly bending the end part of a plate part to which the diaphragm composing the bulkhead of one side small liquid chamber abuts. CONSTITUTION:An abutting plate 40 and a bracket 28 are provided in a liquid chamber 26, so that the liquid chamber 26 may be partitioned into upper and lower liquid chambers 26A and 26B. The bending part outer periphery of a flange part 40B is a smooth surface, the thick wall part 16A of a diaphragm 16 abuts a smooth bending part outer periphery of the flange part 40B, and does not abut the edge part 24E of a flange part 28A. The thick wall part 16A of the diaphragm 16 is not damaged by the edge part 24E even if it is strongly sandwiched between the outer peripheral part 11A of a bottom plate 11 and the lower end flange part 14A of a connection plate 14. Thus durability of a vibration-proofing device can be improved. |
