PROBLEM TO BE SOLVED: To adhere rubber of a dynamic damper to a bracket of an insulator and a mass with sufficient strength for a vibration control device wherein the dynamic damper is attached on the insulator. SOLUTION: An elastic body 17 made by extrusion molding the rubber is provided with plural protrusions 17b on an adhesion surface 17a adhered to an outer cylinder 12 of the insulator I, and plural protrusions 17d and a pair of positioning protrusions 17e on an adhesion surface 17c adhered to the mass 18 of the dynamic damper D. The thickness of an adhesive 19 is secured and the adhesive strength of the outer cylinder 12 and the mass 18 with respect to the elastic body 17 is improved by the function of the protrusions 17b and 17d as spacers. Further, the mass 18 is positioned and the adhesive accuracy is improved by bringing a pair of the positioning protrusions 17e into contact with both ends 18b of the mass 18.
