The present invention relates to an apparatus for reducing high-frequency noise in a transmission cable for automobiles, and in the related art, a cable guide for supporting a transmission cable and a packing for performing a watertight function are composed of one body. The high-frequency joint transmitted as it is and transmitted through the packing spreads widely on the body panel, reducing the quietness, ride comfort, and emotional satisfaction of the occupants.
Therefore, in the present invention, in constructing a device for reducing high-frequency joints of a vehicle transmission cable that reduces the transmission of high-frequency joints generated by rotation of a transfer gear of a transmission to a vehicle body panel, the packing base 100 having a guide installation hole 110 in the center. ); It is installed to protrude from the front end of the packing base 100 to exhibit a watertight function by blocking the packing hole of the vehicle body panel, and the outer shape has a shape corresponding to the packing hole, and the center is an inner border of a predetermined size so that the guide installation hole 110 is exposed. Packing 200 made of rubber material with holes 210; A cable guide 400 that is formed separately from the packing 200 and is assembled in the guide installation hole 110 of the packing base 100, and guides the shifting cable 300 passing through the central cable hole 410 when operating In this invention, the high-frequency joint transmitted to the cable guide 400 through the shifting cable 300 is not well transmitted to the vehicle body panel by the separately formed packing 200, so that satisfactory quietness and riding comfort are provided for the occupants. It is a very useful invention that can provide a high emotional satisfaction by providing.
