PURPOSE:To lower manufacturing cost by reducing parts in number, and also simplifying each work process. CONSTITUTION:An inner cylindrical fitting 16 connected to an engine and the like is installed within the circular member 12A of an installation frame 12 via an elastic body 14. A window section 20 is formed in the circular member 12A, and a cut-out section 14A forming a pressure receiving liquid chamber 28 is formed in response to the window section 20. A box-shaped casing 22 the lower side of which is released, is disposed within the cut-out section 14A. A diaphragm 24 covering the opening of the casing 22 is disposed at the lower side of the casing 22, and an orifice and an auxiliary liquid chamber 30 are disposed within the casing 22. By this constitution, when the vibration control device is manufactured, an intermediate and an outer cylinder can be eliminated, and a drawing process for the outer cylinder and a press-in process to the bracket of the outer cylinder is also eliminated as the outer cylinder is eliminated. |
