PROBLEM TO BE SOLVED: To provide a vibration reduction device by combining an additional spring mechanism to a rotary inertia mass mechanism to absorb high vibration frequency components, to downsize a device, and to reduce the weight.SOLUTION: A vibration reduction device A for reducing a relative vibration between two members relatively vibrating, is constituted by connecting a rotary inertia mass mechanism 1 and an additional spring mechanism 2 in series, and additionally by inserting a ball screw 5 of the rotary inertia mass mechanism 1 into an inner tube 12 of the additional spring mechanism 2. |
