PURPOSE: A dynamic damper is provided to set a required weight according to a frequency domain by installing a weight closure on a pair of supporting plate and filling liquid mass as much as the required mass to the weight closure according to a frequency domain. CONSTITUTION: A dynamic damper comprises a pair of supporting plates(11) which is installed in the both end point part of the top surface of a base supporting plate(10) and performs a plate-spring role, a high damping material(12) which is attached to both sides of a pair of the supporting plates and absorbs and controls vibration, a weight closure(13) which is installed in the top part of a pair of the supporting plates in order to support the both sides of a lower surface and wherein a weight gateway is formed in one side of an upper surface, and liquid weight which fills through the weight gateway in the weight closure as the weight which is necessary according to the frequency domain. |
