The present invention relates to a coupling structure of a link rod connecting an operating lever and an interlocking lever used in a vehicle, and interlocked with an operating lever 110 and an operating lever 110 installed to operate a mechanical device used in the vehicle. In the link rod 100 is connected directly to the mechanical device and the linking lever 120 and the operating lever 110 and the linkage lever 120, the link rod 100 is bent at both ends in the same direction Coupling parts (101, 102) are formed, and the flanges (103) are welded and fixed to the coupling parts (101, 102), one end of which is a pivoting piece (111) hinged to the actuating lever (110). The connection hole is inserted into the coupling hole (111a) of the other end, and the other end is fitted into the coupling hole (121a) of the rotating piece 121 hinged to the interlocking lever (120), thereby connecting the conventional link rod first jaw joint and Connect to the second jaw joint and work on the first and second jaw joints. By eliminating the inconvenience of connecting and installing the lever and the interlock lever, it is possible to facilitate the connection installation work of the link rod 100 to the operating lever 110 and the interlock lever 120, the number of work processes and parts are reduced As a result, workability can be improved and manufacturing cost can be reduced.
