BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below. FIG. 1 is an external view showing an overfender as an example of an exterior component mounted on a vehicle body, and FIG. 2 is a view of FIG.
FIG. 3 is a sectional view taken along the line AA. The over fender is an integrally molded product made of synthetic resin by injection molding or the like, and there are various shapes depending on the target vehicle type and the like. One shape example of the over fender 10 shown in FIG. 1 is shown.

The over fender 10 has a shape that bulges toward the front surface (design surface) side, and clip mounting portions 14 are integrally formed on the back surface thereof at a plurality of positions along the length direction. Mounting hole 14 for each clip mounting portion 14
Clips 18 are attached to a as shown in FIG. By inserting the clip 18 into the through hole of the vehicle body 30, the over fender 10 can be attached to the body 30. In the overfender 10, a protector 20 that is continuous in the length direction of the overfender 10 is attached to the joint portion 12 with the surface 30a of the vehicle body 30.

FIG. 3 is an enlarged sectional view showing the protector 20 attached to the joint portion 12 in a free state, and FIG. 4 is a sectional view showing the protector 20 with the overfender 10 mounted on the body 30. As is clear from these drawings, the protector 20 includes an elastic portion 22 formed of a soft material and an attachment portion 24 formed of a hard material.
The elastic portion 22 has a hollow shape as a whole. The soft elastic portion 22 is made of, for example, EPDM foamed and formed into a sponge shape, and the hard mounting portion 24 is also made of EPDM formed to have a hardness of 70 ° ± 5, and these are integrated. ing.

Locking legs 26 made of the same material as the mounting portion 24 are formed at predetermined intervals in the length direction of the protector 20. These locking legs 26 are inserted into the grooves 16 (engagement recesses) formed in the joint 12 of the overfender 10, whereby the protector 20 is attached to the joint 12. A convex portion 28 is formed on the mounting portion 24 on the opposite side of the locking leg portion 26, that is, in the hollow portion. The convex portion 28 is for pushing the locking leg portion 26 into the groove 16 by pushing the convex portion 28 from the outside of the elastic portion 22 with a roller or the like. Therefore, the convex portion 28
Is located on the coaxial line with the locking leg portion 26, and its outer shape is a gentle spherical surface.

Of the bulge of the elastic portion 22, the most bulged top portion 22a is a distance S inward of the overfender 10 (downward in FIG. 3) with respect to the axis of the locking leg portion 26.
It is only offset. The elastic portion 22 is
Notch 22 formed on the inner wall surface in the lower part of FIG.
b. Due to the cutout portion 22b, the elastic portion 22 is partially thinned toward the inner side of the overfender 10. Further, the elastic portion 22 is provided with a gap concealing portion 22c protruding in a flat plate shape on the outer side of the over fender 10.

The protector 20 thus constructed is
First, the overfender 10 is attached to the joint portion 12, and in that state, the overfender 10 is attached to the vehicle body 30. When the protector 20 is attached to the joint portion 12, the locking leg portion 26 is inserted into the groove 16 with the hard attaching portion 24 being in contact with the joint portion 12. For this insertion operation, the locking leg portion 26 can be efficiently pushed into the groove 16 by pushing the convex portion 28 from the outside of the elastic portion 22 with a roller or the like.

The overfender 10 is attached to the body 30.
The elastic portion 22 is compressed between the joint portion 12 and the surface 30a of the body 30 and is deformed as shown in FIG. At this time, as described above, since the top portion 22a is biased inside the over fender 10, the elastic portion 22a
Deforms to fit inside the over fender 10. Therefore, the elastic portion 22, that is, the protector 20 is not exposed to the outside of the over fender 10 to improve the design, and it is not necessary to match the color of the protector 20 with the color of the vehicle body 30.

In addition to the deformation of the soft elastic portion 22 toward the inside of the overfender 10, the elastic portion 22 is provided with the cutout portion 22b for partially thinning the wall thickness thereof. The reaction force of 22 can be reduced. Moreover, the joint portion 1 of the over fender 10
2 has a tapered surface 12a inside the portion where the groove 16 is formed, and this tapered surface 12a also serves to release the reaction force of the elastic portion 22 deformed in the state of FIG. In this way, by reducing the reaction force of the elastic portion 22 with respect to the over fender 10 as much as possible, the over fender 10
The problem that the edges of the overfloat are lifted from the surface 30a of the body 30 is solved, and the overfender 10 can be installed well.

On the other hand, at the edge of the overfender 10, a gap concealing portion 22c sandwiched between the joint portion 12 and the surface 30a of the body 30 is located. This gap hiding part 2
With 2c, even a slight gap generated at the edge of the over fender 10 can be closed, and the designability is improved, and
It is possible to prevent wax and the like from clogging with the body 30. Furthermore, the gap concealing portion 22c can prevent the overfender 10 and the surface 30a of the body 30 from directly contacting with each other, resulting in peeling or scratching of the coating, thereby preventing rusting of the body 30.

FIG. 5 is a sectional view showing the protector 20 in a different state in a free state. The elastic portion 22 of the protector 20 includes a cutting portion 122b in a state where a portion located in the lower part of the drawing is cut out, instead of the cutout portion 22b. The cutting portion 122b can also suppress the reaction force of the elastic portion 22 with respect to the over fender 10 when the over fender 10 is attached to the body 30. The cutting portion 122b is shown in FIG.
Instead of completely cutting off a part of the elastic portion 22 as described above, a slit-shaped cut may be formed at a portion corresponding to the cutout portion 22b.

As described above, in the protector 20, the elastic portion 22 for the exterior parts such as the over fender 10 is provided.
Since the reaction force can be reduced, it is possible to improve the erection of the exterior parts and enhance the design. Further, it is not necessary to match the color of the protector 20 with the color of the body 30, and the types of the protector 20 can be unified to reduce the cost.
