  • Patent number: 8746108
    Abstract: A damping system for a shift cable is disclosed, in which vibrations and noises that are generated by a transmission and transmitted into the interior of a vehicle through a shift cable are considerably reduced across a damper, that is positioned in a bottleneck section of a socket housing and contacts with bottleneck section, such that it is possible to effectively exclude vibrations and noises transmitted into the interior of a vehicle. Further, the present invention is advantageous in terms of the cost and weight, because a rubber damper is used instead of a mass damper, and it is possible to reduce vibrations and noises without increasing force for operating a shift lever and maximally prevent the function of reducing vibrations and noises from being deteriorated by frictional wear.
