The transmission cable 10 is fixed to the transmission case or the cable bracket 40 attached to the vehicle body via an abutment 50 on the engine room side.

Since the transmission cable 10 extends from the engine room through the dashboard to the room, various types of operating noise such as rattle noise, whine noise, (10) to the room to cause an uncomfortable feeling to the occupant.

Therefore, conventionally, as shown in FIG. 1, a so-called "mass damper" 60 made of heavy heavy material is inserted into the transmission cable 10 (see Patent Document 2) A grommet and a damper made of a rubber material are installed on a protection member attached to the penetrating portion to prevent noise from being transmitted to the vehicle interior by blocking or attenuating the vibration frequency transmitted along the transmission cable 10 Thereby blocking the inflow.

However, in the technique described in Patent Document 2, since the mass damper 60 having an excessive weight is to be added, material costs and assembly costs are increased, and when the mass damper 60 is calked and fixed to an outer cable tube There is a problem that the operation of the shift lever is deteriorated by interfering with the smooth movement of the wire by pushing the wire inside the outer ray tube.

Also, the technique of Patent Document 3 has a problem that the structure of the retainer becomes very complicated from the manufacturing process, and the vibration from the transmission is transmitted to the retainer and the dashboard, which may cause another noise.

As another example of the conventional noise blocking technique, there is disclosed a technique in which a part of a damper is extended from a fixture fixed to a cable bracket to interpose noise between a socket cover and an external ray tube, as in Patent Documents 4 and 5, There is a problem in that the noise damper is not effective enough to add the mass damper again or to add another noise shielding means.

On the other hand, the noise induced vibrations transmitted to the terminal rod 130 are generated by the second flow path which is directly transmitted to the wire 104 and intended to be transmitted to the indoor side.

The present invention allows the noise-induced vibrations to be attenuated during the first and second flow paths so that the action is exerted in the outer case 210. That is, the mass damper, which is installed separately in the middle of the cable 100, is excluded, and instead, the case 210 of the cable clamp 200 has its function properly combined.

To this end, the cable fixture 200 of the present invention is provided such that the mass damper 300, which is a weight body, forms a unit body on the body of the outer case 210. And an outer case 210 having a function of attenuating the noise induced vibration by the mass damper 300 of the heavy body.

The connection damper 240 is made of a soft plastic or rubber having a different material from the outer case 210, that is, having a different natural frequency. Therefore, vibration of the predetermined frequency is also attenuated by the connection damper 240.

 The mass damper 300 is made of a material having a very large mass (preferably a metal; a conventional mass damper and a conventional mass damper), as compared with the outer case 210, the casing cap 220, the guide pipe 230, The same metal). Accordingly, when the mass damper 300 is integrated with the outer case 210, the outer case 210 can attenuate the noise-induced vibrations in different frequency bands from other elements.

According to the first embodiment, the mass damper 300 is constructed by integrating the first mass damper 300a, which is an annular weight, by embedding by insert molding when the outer case 210 is manufactured. Injecting the first mass damper 300a made of an annular weight by insert molding at the time of manufacturing the outer case 210 can easily integrate the first mass damper 300a into the outer case 210 without detachment And the first mass damper 300a are integrally provided without a gap over the entire circumference of the outer case 210, smooth transmission of the noise induced vibration to the first mass damper 300a is achieved, The damping efficiency of the damper 300a can be maximized.
