PROBLEM TO BE SOLVED: To prevent the generation of the tensile strain in a stopper and improve the durability by providing a rubber elastic material crossing inside the outer cylinder including an inner cylinder, forming recesses in the inner cylinder, and by providing a rubber stopper with its surface projected therein. SOLUTION: An inner cylinder 1 is elastically supported by a rubber elastic body 3 in an outer cylinder 2. The elastic body 3 includes the inner cylinder 1 and is so provided as crossing inside the outer cylinder 2, spaces 4, 5 are provided in its upper/lower parts, recesses 7 are formed in the top/bottom faces of the inner cylinder 1, and a rubber stopper 6 whose surface is projected to the lower space 5 is provided thereto. An engine-side attachment member is inserted inside the inner cylinder 1 and the outer cylinder 2 is attached to a car body side via bracket. If the stopper repeatedly collides with the lower internal circumferential face of the outer cylinder 2 with the vibration and subjected to the compression force repeatedly, the stopper 6 is provided in the recess 7 so that this constitution can suppress the tensile strain generated on the adhesive face and improve the durability of the stopper 6. |
