PROBLEM TO BE SOLVED: To provide a cylindrical fluid-filled vibration isolator to be suitably used for a differential mount, having a simple structure, and capable of exhibiting the high damping effect. SOLUTION: A deformed shaft member 1 having the outside diameter perpendicular to the outside diameter in the main vibration input direction, larger than it is adopted, shade-shaped elastic stopper projecting parts 34 projecting from the deformed shaft member 12 to the main vibration input direction are formed in fluid chambers 48, 48 formed between the deformed shaft member 12 and an outer cylindrical member 14, and thin parts 44 are provided by forming lightening holes 42 on peripheral both side walls of the fluid chambers 48. Therefore, the effective dashpot action can be achieved on the basis of the displacement of the elastic stopper projecting parts 34 in the fluid chambers. |
