Conventionally, as shown in FIG. 9, a seal sponge 55 is set on the wheel arch portion 50a and the seal sponge 55 is attached to the inner surface of the bumper side portion 51a in order to prevent the muddy water from hanging down on the bumper surface. The gap A may be covered by contact.
[0005]
[Problems to be solved by the invention]
However, in the above-mentioned conventional split line portion structure, it is necessary to separately add a seal sponge, so that the number of parts increases and the number of work steps for sticking to the fender panel increases, so that the cost increases.
[0006]
The present invention has been made in view of the above-mentioned conventional situation, and has a split line structure between a vehicle body side panel and a bumper side portion that can prevent rainwater, muddy water, etc. from dripping on a bumper surface without increasing the number of parts and the number of working steps. It is intended to provide.
[0007]
[Means for Solving the Problems]
The present invention relates to a split line structure between a vehicle body side panel and a bumper side portion, wherein a flange is formed in a wheel arch portion of the vehicle body side panel, and a bumper side portion is provided with a gap in the flange. A concave portion extending in the front-rear direction and enlarging a gap with the bumper side portion is formed so as to bulge inside the vehicle.
[0008]
According to a second aspect of the present invention, in the first aspect, a plurality of the recesses are formed at intervals in a vehicle front-rear direction, and between the recesses, a convex portion abutting on an inner surface of the bumper side portion is formed so as to protrude outward. It is characterized by having.
[0009]
Operation and Effect of the Invention
According to the score line structure according to the present invention, since the concave portion for enlarging the gap with the bumper side portion is formed in the flange of the vehicle body side panel so as to expand, a part of rainwater or the like wound up by the wheel enters the concave portion from the gap. Then, since the concave portion is wider than the gap, the pressure of the rainwater is weakened in the concave portion, and the rainwater hardly rises above the narrower portion than the concave portion. As a result, rainwater or the like flows down in the front-rear direction along the concave portion, and it is possible to prevent the rainwater from hanging down from the score line portion to the bumper surface, thereby preventing the appearance from being deteriorated.
[0010]
In the present invention, the recess is formed by simply forming a recess extending in the vehicle front-rear direction on the flange. Therefore, the recess can be formed simultaneously when the side panel is press-formed, and the number of parts and the number of working steps due to the conventional seal sponge can be increased. There is an effect that it can be unnecessary and cost can be reduced.
[0011]
According to the second aspect of the present invention, since the convex portion abutting on the inner surface of the bumper side portion is formed between the concave portions of the flange, sticking of the bumper side portion can be prevented, and the dividing line between the side panel and the bumper side portion. There is an effect that the step of the part can be reduced and the appearance can be improved.
[0012]
In addition, since the convex portion is in contact with the bumper side portion, the surface rigidity at the bumper mounting portion of the side panel can be increased, and the rigidity against impact from the side can be improved. Further, since a convex portion is formed between the concave portions, rainwater or the like entering from the above-described gap is prevented from entering upward by the convex portion, and rainwater or the like can be prevented from dripping from the score line portion.

Since the extension portion 39 is formed integrally, rainwater, muddy water, and the like, which are wound up by the front wheel 12, are prevented from entering the gap A by the extension portion 39, whereby the rainwater or the like hangs down from the secant line portion B to the bumper surface. Can be prevented, and deterioration of appearance can be prevented.
[0039]
As described above, in the present embodiment, the extended portion 39 of the fender liner 30 prevents most of the rainwater that has entered the gap A, and a part of the rainwater that has entered the gap A is removed by the recess 26 of the flange 10. , 27 are prevented from entering further upward, so that it is possible to reliably prevent rainwater or the like from dripping from the dividing line portion B.
[0040]
In the present embodiment, when the fender liner 30 is molded, the extension 39 is formed at the same time. Therefore, it is possible to prevent rainwater from drooping without increasing the number of parts and the number of working steps, as compared with the case using a conventional seal sponge. Cost can be reduced.
[0041]
In the present embodiment, since the concave groove portion 36 swelling downward is formed in the outer edge portion 30e, rainwater and the like flowing along the cowl, the pillar and the like are collected in the concave groove portion 36, and the fender panel 10 It is possible to prevent rainwater or the like from leaking from between the fender liner 30 and prevent rainwater or the like from adhering to a tire or a wheel disc, thereby preventing deterioration in appearance.
[0042]
Further, since the groove 36 is formed in the outer edge 30e, even if the bumper side 18b hits the extension 39 due to a variation in assembling the bumper side 18b, the fender liner 30, etc., the groove 36 bends and the extension 39 is bent. And the bumper side portion 18b can be prevented from floating outward, and the assembling accuracy can be secured.
[0043]
In the present embodiment, the front and rear portions of the concave groove portion 36 are inclined downward so as to be located lower than the center portion, so that rainwater and the like flowing along the cowl panel, the front pillar, and the like are transmitted in the vehicle front-rear direction. And it is possible to more reliably prevent rainwater or the like from leaking from between the fender panel 10 and the fender liner 30.
[0044]
In the above embodiment, the case where the present invention is applied to the front side fender portion has been described as an example. However, the present invention can naturally be applied between the quarter panel 11 of the rear side fender portion and a rear fender liner (not shown). In this case, the same effect as in the above embodiment can be obtained.
