VIBRATION REDUCING DEVICE
The present invention relates to a vibration reduction device, and more particularly, to a vibration reduction device capable of reducing rolling noise by reducing vibration in a low-frequency region as well as vibration in a high-frequency region. A vibration reduction device according to an exemplary embodiment of the present invention includes: a pair of damper main bodies disposed at both sides with a web portion of a rail interposed therebetween, such that at least a part of the damper main body is in contact with the web portion and at least another part of the damper main body is in contact with a lower end portion of the rail which is connected to the web portion; a plurality of inelastic collision balls provided in at least two through holes formed in each of the pair of damper main bodies so as to be movable with respect to the web portion or the lower end portion; and a pair of housings configured to surround the pair of damper main bodies from the outside in order to prevent the damper main bodies from being exposed to the outside.
