PROBLEM TO BE SOLVED: To provide a vibration isolating system which is provided with vibration isolation characteristics by improving durability of a stopper rubber, and suitably secures vibration isolation characteristics by improving durability of a support arm part. SOLUTION: The vibration isolation system is provided with: an inner tube 2; an outer tube 3 axially parallel with the inner tube 2 and surrounding it; and a rubber elastic body 4 connecting the inner tube 2 and the outer tube 3. It is provided with a pair of hollow parts 5 axially piercing the rubber elastic body 4 and positioned on both sides of the inner tube 2, and the stopper rubber 6 provided in at least one hollow part 5 and protruding from the outer tube 3 toward the inner tube 2. The inner tube 2 has an outline with a non-circular cross section, and a curvature of a first outer circumference face portion 21 facing the stopper rubber 6 of the inner tube 2 is the same as a curvature of an inner circumference portion 31 of the outer tube 3 facing it on the other side of the stopper rubber 6.
