PROBLEM TO BE SOLVED: To provide a liquid enclosing type vibration control device by setting the lowest value of a dynamic spring in the vertical and longitudinal directions of a vehicle to the vicinity of a specific value (400) Hz to reduce axle-gear noise. SOLUTION: This vibration control device is formed of a boring 6 composed of a through-hole in an axial direction, and a liquid chamber 20 for enclosing fluid 21, in a tubular elastic body for fixing its inner peripheral surface to an inner tubular body 2, and its outer peripheral surface to an outer tubular body 4. In this device 18, the liquid chamber 20 is formed on the axis in a vehicle right and left direction (C), and also the boring 6 is formed on the axis in a vehicle longitudinal direction (B); and the liquid chamber 20 is formed by dividing it into two chambers in the vehicle vertical direction (A) over in the direction (B) by a partitioning wall 23 forming a gap 24 in the direction (C). |
