However, in this rear wheel house structure, as shown in FIG.
The welded portion protrudes to form a welding trace 76A. Therefore, when the wire harness 70 moves due to vibration or the like, the wire harness 70 and the welding mark 76A may interfere with each other, as shown by the imaginary line in FIG. 5, and the wire harness 70 may be damaged. .

Further, as shown in FIG. 6, an edge portion 80 of an insulator 80 is provided near the wire harness 70.
There is an A. Therefore, due to vibration etc., the wire harness 7
If 0 moves, as shown by the imaginary line in Figure 6,
The wire harness 70 and the edge portion 80A of the insulator 80 may interfere, and the wire harness 70
There was a problem with the product being damaged.

As a method to improve these problems, a resin protector 8 is installed around the outer periphery of the wire harness 70.
It is known that damage to the wire harness 70 can be prevented by wrapping the wire harness 70 around the wire or fixing the wire harness 70 with a clamp material, but in this case, there is a problem in that it leads to a significant increase in cost.

SUMMARY OF THE INVENTION In view of this fact, it is an object of the present invention to provide a rear wheel house structure that can prevent damage to the wire harness without causing a significant increase in cost.

[0008]

[Means for Solving the Problems] In the rear wheel house structure according to claim 1, a wire harness is disposed on the side of a mating flange between a wheel house inner and a wheel house outer, and the wire harness and the mating flange and a rear wheel house structure covered by an interior trim, the rear wheel house structure covering a side surface of the wire harness of the wheel house inner, and protruding toward the interior trim side at an end on the mating flange side to connect the wire harness and the mating flange. It is characterized by comprising an insulator having a convex portion interposed therebetween.

[0009]

[Operation] In the rear wheel house structure configured as described above, the convex portion of the insulator is interposed between the wire harness and the mating flange. Therefore, even if the wire harness moves, the convex portion can prevent welding marks between the wire harness and the mating flange and interference with the edge portion of the insulator covering the wheel house inner. Therefore, there is no need to wrap a protector around the wire harness, and there is no need to fix the wire harness with a clamp material, so damage to the wire harness can be prevented without causing a significant increase in cost.

[Embodiment] An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

In the figure, arrow FR indicates the forward direction of the vehicle body, arrow UP indicates the upward direction of the vehicle body, and arrow IN indicates the inner direction in the vehicle width direction.

As shown in FIG. 3, the rear portion 10A of the automobile body 10 is equipped with electrical components such as a tail lamp 12 and a trunk illumination light (not shown). These electrical components are connected by a wire harness 14 to a control device and a battery provided at the front of the vehicle body.

As shown in FIG. 2, at the rear of the cabin of the automobile body 10, the wire harness 14 is inserted through a through hole 18 formed in the quarter panel inner 16.
It is inserted into the cabin of the quarter panel inner 16 and reaches the locker 22 along the outer periphery of the wheel house 20.

As shown in FIG. 1, the wheel house 20
is composed of a wheel house outer 24 that constitutes the outer side of the wheel house 20 in the vehicle width direction, and a wheel house inner 26 that constitutes the inner side of the wheel house 20 in the vehicle width direction. The inner end of the wheel house outer 24 in the vehicle width direction is bent toward the opposite side from the wheel 28 to form a flange 30. Further, the outer end in the vehicle width direction of the wheel house inner 26 is bent toward the opposite side from the wheel 28 to form a flange 32, and the width of the flange 30 of the wheel house outer 24 is
The flange 32 of 6 is made wider.

Flange 32 of wheel house inner 26
The wheel facing surface 26A of the wheel house inner 26 and the wheel facing surface 2 of the wheel house outer 24 are attached to the flange 30 of the wheel house outer 24 from the inside in the vehicle width direction.
The connecting portion with 4A is brought into contact so as to be flush with each other, and serves as a mating flange 33. This mating flange 3
3 are spot welded at predetermined intervals along the circumferential direction of the wheel house, and welding marks 35 protrude from these spot welds.

Wheel 28 of wheel house inner 26
On the opposite side, an insulator 34 is arranged along the inner wheel house 26 and covers the inner wheel house 26. The outer end of the insulator 34 in the vehicle width direction projects toward the side opposite to the wheel 28 and forms a convex portion 36 . The convex portion 36 has a substantially L-shaped cross section with a height H2, and the tip of the upright portion 36A is
It is bent at a substantially right angle toward the flange 32 side of the wheel house inner 26, forming a bent portion 36B. That is, the upright portion 36A of the convex portion 36 contacts the wire harness 14, and the insulator 34 is located at the tip of the bent portion 36B.
The edge portion 34A is configured not to interfere with the wire harness 14.

Flange 30 of wheel house outer 24
is covered with the interior trim 38. A portion of the interior trim 38 that faces the flange 32 of the wheel house inner 26 (a portion up to a distance H1 from the insulator 34) is bulged inward in the vehicle width direction, and serves as a bulge portion 40. The inner end of the bulging portion 40 in the vehicle width direction is bent at a substantially right angle toward the insulator 34.
A, and the tip of this bent portion 40A is close to the insulator 34.

The wire harness 14 is inserted between the bent portion 40A of the bulged portion 40 of the interior trim 38 and the convex portion 36 of the insulator 34. Moreover, the gap H1- between the interior trim 38 and the convex portion 36 of the insulator 34 is
H2 is equal to or less than the diameter D of the wire harness 14 (H1-H2
≦D), and this gap is connected to the wire harness 14.
is not allowed to pass through.

Next, the operation of this embodiment will be explained. In the rear wheel house structure configured as described above, the wire harness 14 is inserted within the bulge 40 of the interior trim 38 between the convex portion 36 of the insulator 34 and the bent portion 40A. Further, the gap H1-H2 between the interior trim 38 and the convex portion 36 of the insulator 34 is
The diameter is less than or equal to the diameter D.

Therefore, when the wire harness 14 moves toward the welding mark 35 side of the mating flange 33 due to vibration or the like, the wire harness 14 comes into contact with the upright portion 36A of the convex portion 36 and is connected to the interior trim 38. Insulator 3
It does not pass through the gap with the convex portion 36 of No. 4. Therefore, the wire harness 14 does not interfere with the welding marks 35 of the mating flange 33. In addition, the insulator 34
The bent portion 36B of the convex portion 36 of the wheel house inner 2
6 toward the flange 32 side, so that the wire harness 14 does not interfere with the edge portion 34A of the insulator 34.

[0021] Therefore, there is no need to wrap a protector around the wire harness 14, and there is no need to fix the wire harness with a clamp material, so damage to the wire harness 14 can be prevented without causing a significant increase in cost. can.

Further, in this embodiment, the surface rigidity of the insulator 34 is improved by the convex portion 36 of the insulator 34. Therefore, when the insulator 34 is attached to the wheel house inner 26, vibrations, whirling, etc. of the insulator 34 are reduced, making it easier to support the insulator 34, and interference between the insulator 34 and the wheel house inner 26 is reduced. , the workability of assembling the insulator 34 is improved.

In the rear wheel house structure of this embodiment, the cross-sectional shape of the convex portion 36 of the insulator 34 is approximately L-shaped, but the cross-sectional shape of the convex portion 36 of the insulator 34 is not limited to this. For example, as shown in FIG. 4(A), it may be approximately U-shaped. In addition, Fig. 4 (B
), it may be approximately J-shaped. In addition, the height of these convex parts 36 is set to H2, and the gap H1-H2 between the interior trim 38 and each convex part 36 is below the diameter D of the wire harness 14.
