A mechanism 6 is provided. 7a and 7b are door lock cables (hereinafter referred to as cables). One end of the cable 7a is connected to the door lock opening portion 6a of the door lock mechanism 6, the other end is connected to the inside handle 4, and one end of the cable 7b is the door lock mechanism. The other end is connected to the locking / unlocking portion 6b, and the other end is connected to the lock knob 5. Reference numeral 11 denotes a vibration generated when the vehicle is running while holding an intermediate portion between the cables 7a and 7b.
7b is a cable holder for preventing interference with a door panel or the like. As shown in FIG. 3, it is a prism-shaped sponge rubber body, and has a slit 11a having an upper end opening between opposing side surfaces. A double-sided adhesive tape 12 is attached to the entire surface of one side surface parallel to the existing direction, and the cable holder 11 is adhesively fixed to the door inner panel 8 by the double-sided adhesive tape 12. In the figure, reference numeral 101 denotes a door glass which moves up and down the window opening of the door 1 to open and close.

In holding the cables 7a and 7b, one ends of the cables 7a and 7b are connected to a door lock opening portion 6a and a locking / unlocking portion 6b, respectively, and then an intermediate portion of the cables 7a and 7b is connected to a door inner. The slits 11a of the cable holder 11 previously bonded and fixed to the panel 8 with the double-sided adhesive tape 12 are inserted from the upper end openings and held, and then the other ends of the cables 7a and 7b are moved to the opened door trim 2 side before assembly. Then, the door trim 2 is connected to the inside handle 4 and the lock knob 5 to be closed and assembled.

[0004]

When the cables 7a and 7b are pulled toward the opened door trim 2 when being connected to the inside handle 4 and the lock knob 5, the cables 7a and 7b are removed from the cable holder 11 as shown in FIG. The door trim 2 is easily detached, and the assembling work of the door trim 2 becomes difficult. This is because when the cables 7a and 7b are pulled, the cables 7a and 7b are pulled.
A force is applied to the cable holder 7b to straighten them, and this force pushes one side of the upper end of the cable holder 11 in which the slit 11a is formed to bend, and the cable 7b is bent.
This is because a and 7b escape.

Accordingly, the present invention has been made in view of such a problem, and it is an object of the present invention to provide a cable holding structure which is easy to assemble without detaching from a cable holder even when the cable is pulled toward a door trim. It is something.

[0006]

According to the present invention, an intermediate portion of a cable connecting a door lock operating portion provided on a door trim of a vehicle and a door lock mechanism installed inside the door is slit into a sponge rubber body. In the cable holding structure in which the cable holder is adhered and fixed to the door inner panel, the slit of the cable holder is formed by penetrating the sponge rubber body. The cable is inserted through the slit, and one side surface of the cable holder parallel to the slit penetrating direction is adhesively fixed to a door inner panel at a lower end thereof.

In the present invention, since the cable is inserted into the slit penetrating the inside of the cable holder, the cable does not come off from the cable holder. And since the cable holder fixed only the lower end of one side to the door inner panel, when pulling the cable, the whole cable holder falls down in a bent shape to bring the cable closer to a straight line, and when the door trim is assembled, The cable holder is restored to the upright state by the elasticity of the sponge rubber.
