PROBLEM TO BE SOLVED: To provide a liquid-sealing type vibration control device which can absorb variation in dimensional accuracy and flatness of the jointed surface of respective members and improves sealability. SOLUTION: This liquid-sealing type vibration control device is provided with the first metal fitting of bottomed tubular shape, the second metal fitting located inside the first metal fitting disposed coaxially, a middle tubular metal fitting 3 having tapered tubular part mounted between the first and second metal fittings a roughly tubular rubber elastic body 4 fitted between the middle tubular metal fitting 3 and the second fitting metal, a diaphragm which is retained against the first and second metal fittings and is formed with a liquid- sealing chamber between rubber elastic body 4 and it, and a partition member 6 which is fitted, pressed in the tapered tubular part of the middle tubular metal fitting 3, and partitions the fluid sealing chamber into a main fluid chamber and a sub fluid chamber to form an orifice passage. The inclination angle (α) of the tapered tubular part of the middle tubular metal fitting 3 is set so as to be smaller than inclination angle (β) of the press-in surface of the partition member 6 to be pressed in the tapered tubular part. |
