DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable supporting structure for supporting a cable such as an accelerator cable on a partition panel such as a dash panel.

[0002]

2. Description of the Related Art As a conventional cable support structure, for example, there is a structure for an accelerator cable shown in FIGS.

First, a casing end 5 connected to an outer tube 3 of an accelerator cable 1 is shown in FIG.
Are formed integrally with the stopper bracket 7 by outsert molding. The stopper bracket 7 has upper and lower fastening portions 7a and 7b, and is fastened and fixed to a surface 13a of the dash panel lower 13 on the vehicle interior side by a bolt nut 15 via a seal rubber 17. The casing end 5 is inserted through the through hole 13b of the dash panel lower 13 toward the engine room. 19 is an inner cable of the accelerator cable 1. Further, the stopper bracket 7 is provided with a stopper portion 21 and a buffer rubber (not shown) is attached thereto. An accelerator pedal (not shown) is brought into contact with a rubber (not shown) of the stopper portion 21 to position the accelerator pedal. The one shown in FIG.
The casing end 25 is molded on the outer tube 3 of the accelerator cable 1 and is separate from the stopper bracket 7. Casing end 2
5 is provided with flange portions 25a and 25b extending to the fastening portions 7a and 7b of the stopper bracket 7, respectively.
A and 7b are fastened and fixed to the dash panel lower 13 by bolts and nuts 15.

[0004]

However, in the case of the structure shown in FIG. 6, the casing end 5 is outsert-molded on the stopper bracket 7, so that the stopper bracket 7 itself tends to be large and the weight increases. However, there was a fear that the cost would be increased. 7 does not have the problem shown in FIG. 6 because the casing end 25 and the stopper bracket 7 are separate structures, but the flange portions 25a and 25b of the casing end 25 are connected to the stopper bracket 7. Fastening part 7
In order to fasten to the dash panel lower 13 together with the a and 7b, the collar 27 which receives the axial force of the bolt is required so that the resin flange portions 25a and 25b do not receive a large fastening force, which leads to an increase in the number of parts and an increase in weight. There is a problem.

Therefore, the present applicant has considered a structure as shown in FIG. In the structure shown in FIG. 8, a housing portion 29 is provided in the stopper bracket 7 to house and mount the flange portion 33 of the casing end 31. Specifically, the casing end 31 is molded on the outer tube 3 of the accelerator cable 1 and includes the flange portion 33 and the cylindrical portion 35. The flange portion 33 is formed with an engagement claw 33a as an engagement portion, and has a wire insertion hole 37 through which an accelerator wire inner penetrates at an axial center portion. The stopper bracket 7
The housing portion 29 is provided between the upper and lower portions of the fastening portions 7a and 7b. The housing portion 29 has a support hole 29a facing the through hole 13b of the dash panel lower 13, and a surface including the support hole 29a is formed in a concave shape,
It is configured for the dash panel lower 13.

The flange portion 33 is accommodated in the accommodating portion 29, and an engaging claw 33 a is locked in a support hole 29 a of the accommodating portion 29. The fastening portions 7a and 7b are directly fastened and fixed to the dash panel lower 13 via the bolts and nuts 15, and the flange portion 33 is provided between the surface 13a of the dash panel lower 13 and the housing portion 29 with a seal rubber 39 interposed therebetween. The cylindrical portion 35 is inserted into the through hole 13b from the vehicle interior side to the engine room side.

In such a structure, the seal rubber 39 can seal around the through hole 13b of the dash panel lower 13, and since the casing end 31 and the stopper bracket 7 are separate bodies, the stopper bracket 7 itself becomes large. Further, since the stopper bracket 7 has its fastening portions 7a and 7b directly fastened and fixed to the dash panel lower 13, there is no need for the collar as shown in FIG.

However, in such a structure, the flange portion 33 of the casing end 31 and the dash panel lower 1
Since the seal rubber 39 is interposed between the casing end 31 and the support 3, there is a possibility that the support of the casing end 31 may be loosened in accordance with the set of the seal rubber 39.

Accordingly, the present invention provides a cable support structure which does not increase the size of the stopper bracket, does not require a collar for fastening the stopper bracket, and can stably support the casing end over time. To provide
