PROBLEM TO BE SOLVED: To provide a vibration control device capable of restricting the generation of noise due to repeated abutment/separation of both of peripheral surface parts of bore holes on/from each other. SOLUTION: In this vibration control device, an inner cylinder 1 and an outer cylinder 2 are connected to each other by a rubber elastic body 3 interposed between them, and the rubber elastic body 3 is formed with bore holes 4. The peripheral surface part of the bore hole 4 is formed of a high slidable rubber part 8. The high slidable rubber part 8 is formed by, for example, blending a higher fatty acid amide with rubber as a base. With this structure, when the inner and the outer cylinders 1 and 2 displace from each other, both the peripheral surface parts of the bore holes 4 abut/separate on/from each other. Since the high slidable rubber has a small coefficient of friction, even if the rubber elastic body 3 becomes hard in winter season, the generation of noise can be restricted.
