The present invention related to a dynamic vibration absorber using permanent magnets. More particularly, the dynamic vibration absorber using the permanent magnets, according to the present invention, comprises: a body having a vibration damping means including a plurality of permanent magnets; and a cover connected to the vibration damping means, and coupled to the upper portion of the body to be capable of vertically moving. Moreover, noise and vibration reduction effects can be maximized even if the dynamic vibration absorber using the permanent magnets is installed in an object for reducing the noise and vibration by being capable of adjusting the operation frequent of the vibration absorber because the dynamic vibration absorber using the permanent magnets can adjust an initial gap of the permanent magnets used for the vibration damping means with a simple structure. |
