SUMMARY OF THE INVENTION In view of the above-mentioned problems with the conventional dash panel penetration structure, an object of the present invention is to provide a structure that allows cable penetration to be quickly and easily disposed of.

-Means for Solving the Problems- In order to achieve this object, the present invention provides a structure for passing through a dartshi panel for a cable that passes through at least the vertical wall of the dash panel and leads the cable from the engine room side to the interior of the vehicle. A reinforcing pipe with one end protruding into the engine room is installed passing through the vertical wall, a grommet that can close the end is fixed to the outer case of the cable, and the grommet is fastened with a clip or the like. It is proposed to fix it to the reinforcing pipe by some means.

-Embodiment- Hereinafter, details of an embodiment of the present invention will be explained with reference to FIGS. 1 to 5.

1 and 2 show a first embodiment of the present invention. In this embodiment, a reinforcing panel 2 is fixed at both ends between the vertical wall 1a and the bottom wall 1b of the dash panel 1. is used. That is, the vertical wall portion 1a of the dash panel 1 and the through hole 3 of the reinforcing panel 2,
A reinforcing pipe 11 is passed through the reinforcing pipe 11, and the retainers 7 and 8, which are welded in advance to the middle part of the reinforcing pipe 11, are connected to the corresponding vertical wall part 1a and the reinforcing panel 2.
Seal rubbers 5 and 6 are interposed between them, and they are fixed from inside the vehicle compartment F with mounting bolts 9 and 10, respectively.

Further, one end portion 11a of the reinforcing pipe 11 is placed in a state of protruding into the engine room A, and a cable D is drawn into the reinforcing pipe 11 from inside the engine room A. That is, a grommet 12 having a pair of clips 12a is integrally formed on the circumferential surface of _{the outer case d1 of} the cable D into which the operating inner cable d2 is inserted. As shown in an enlarged view in FIG. 2, this grommet 12 includes a flange 12c having a collar 12b that can come into contact with the opening of the reinforcing pipe 11.
An O-ring 14 is fitted into the circumferential groove 13.
A pair of locking holes 15 are formed in the end 11a of the reinforcing pipe 11 corresponding to the clips 12a, and the grommet 12 is connected to the end 11a of the reinforcing pipe 11.
1a, said clip 12a
falls into the corresponding locking hole 15. On the other hand, reinforcement pipe 1
Since the rubber ring 16 is baked into the opposite end 11b of the reinforcing pipe 11, the cable D passed through the reinforcing pipe 11 passes through the center of the reinforcing pipe 11 without bending.

Since the first embodiment has the above structure,
In order to pass the cable D through, the reinforcing pipe 11 may be fixed to the vertical wall portion 1a of the dash panel 1 and the reinforcing panel 2 using the mounting bolts 9 and 10. In this fixed state, the reinforcing pipe 11 is wrapped around the dash panel 1 and the reinforcing panel 2 that are combined at an angle, so the reinforcing pipe 11 is held in a stable state, and the cable D inserted later can be attached to the vehicle body. It maintains high rigidity even if it is tensed in either the front or back direction. In addition, in order to fix the cable D, the reinforcing pipe 11 must be installed from inside the engine room A.
When the cable D is inserted into the interior of the vehicle compartment F and pulled strongly, the end portion 11a of the reinforcing pipe 11 is closed by the grommet 12, and the clip 12 is inserted into the locking hole 15.
Since a falls, the work can be completed easily. In this assembled state, the O-ring 14 and the rubber ring 1
6 prevents noise from entering the engine room A, but since the cable D passes through the center of the reinforcing pipe 11 under tension, the cable D may collide with the reinforcing pipe 11 due to vibrations of the vehicle body, etc. Noise generation is prevented.

FIG. 3 is a sectional view of a second embodiment of the present invention in which a reinforcing pipe 11A is fixed diagonally between the vertical wall portion 1a and the bottom wall portion 1b of the dash panel 1 bent at a substantially right angle. Both ends 11a and 11b of the reinforcing pipe 11A having this structure are placed in a penetrating state between the through holes 3B and 4B formed in the vertical wall part 1a and the bottom wall part 1b, and are welded to the peripheral surfaces of these in advance. Using retainers 7B, 8B and mounting bolts 9B, 10B, seal rubbers 5B, 6B are interposed between the corresponding vertical wall portions 1a and bottom wall portions 1b, and the retainers are fixed from inside the vehicle compartment F, respectively. Further, the cable D passing through the reinforcing pipe 11A is held by the reinforcing pipe 11A by a grommet 12A and a rubber ring 16A, but although the grommet 12 has a collar 12b and a clip 12a, there is no need for sealing. The O-ring 14 mentioned above is not provided.

Since the second embodiment has the above structure,
Since the darth panel 1 and the reinforcing pipe 11A bent at approximately right angles form a highly rigid truss structure,
Stable support rigidity can be obtained at the penetrating portion of the cable D. To assemble the cable D into the same structure, insert the cable D into the reinforcing pipe 11A from the engine room A side, and firmly pull the tip of the locking hole 15 diagonally downward to the right in FIG. The assembled state shown in the figure is obtained. In this assembled state, the clip 12a of the grommet 12A falls into the locking hole 15 of the reinforcing pipe 11A, so that the cable D is prevented from being pulled out from the reinforcing pipe 11A, and the grommet 1
Since the cable D, which is held at both ends by the rubber ring 16A and the rubber ring 16A, is not loosened inside the reinforcing pipe 11A, the reinforcing pipe 11A and the cable D interfere with each other due to vibrations of the vehicle body, etc., and a collision sound is generated. Never.

FIG. 4 is a sectional view corresponding to FIG. 3 of a third embodiment of the present invention, and the same structural parts as in FIG. 3 are designated by the same reference numerals. The features of the third embodiment are the structure of the grommet 12B integrally molded on the cable D and the grommet 12 for the reinforcing pipe 11A.
It is in the fastening means of B. That is, as shown enlarged in FIG. 5, a grommet 12B having a collar 12b
An annular groove 16 is formed in the flange 12c, and the end 1 of the reinforcing pipe 11A corresponding to the annular groove 16
1a includes a clip pin 1 formed into a “C” shape.
A pair of through holes 18 are formed into which the tip portions 17a of No. 7 can be inserted. Therefore, in such a structure,
After passing the cable D through the reinforcing pipe 11A, insert the clip pin 17 into the reinforcing pipe 11.
Since the cable D can be easily prevented from being pulled out by simply engaging with the through hole 18 of A, the work of disposing the cable D in the car body assembly process can be performed very simply.

-Effects of the invention- As is clear from the above explanation, according to the invention, a cable is inserted inside a reinforcing pipe that is fixed in advance to a darts panel, and after pulling the cable strongly in one direction, a simple It can be assembled by simply fixing the cable grommet to the reinforcing pipe. Therefore, the complicated work required in the narrow engine room as in the past is eliminated, and the work can be carried out quickly.
