The overlapping portion 34 is bent at a substantially right angle from the lining 27 body toward the vehicle side, and four ribs 38 are provided at the lower end portion of the overlapping portion 34 at the corner portion formed by both. In addition, it is preferable to shape | mold the periphery of each rib 38 in the smooth curve shape moderately convex outside.

  6 to 9 show a member coupling relationship between the rear bumper 21 (particularly around the side extension 21a) and the lining 27 or the body 11 side. 6 is a view of the lining 27 (right side) as seen from the inside of the vehicle, and FIG. 7 is a view as seen from below. 8 is a cross-sectional view taken along line AA in FIG. 6, and FIG. 9 is a cross-sectional view taken along line BB and CC in FIG.

  First, the assembly of the rear bumper 21 and the lining 27 will be described. The lining 27 is attached to the body 11 before mounting a tire or the like on the vehicle. In this case, the left and right linings 27 are fixed to the body 11 side by the clips 26A, 26B, and 26C, respectively. As shown in FIGS. 8 and 9, the lining 27 is fixed to the bumper stay 28 by clips 26 </ b> A and 26 </ b> C at a fixing portion 35. Further, it is fixed to the body 11 by a clip 26B at a fixing portion 36.

  Next, the rear bumper 21 is assembled from the rear side of the body 11 (see FIG. 10A). FIG. 10 schematically shows the relative positional relationship between the side extension 21a and the lining 27 when the rear bumper 21 is attached. Represents). The flange 31 of the rear bumper 21 abuts against the rib 38 of the lining 27 (see FIG. 10B), particularly around the side extension 21a of the rear bumper 21, and at this time, the lining 27 is pressed by the flange 31 once. Escape to front Fr. Since the lining 27 is made of a thin and flexible resin material as compared with the rear bumper 21, it is easily elastically deformed. When the rear bumper 21 reaches the proper mounting position, the rear bumper 21 is fixed to the body 11 side by a fixture 26 (screw or the like). The flange portion 32 is also engaged with a bumper holder 39 (FIG. 2) fixed in advance to the body 11.

  The elastically deformed lining 27 is pushed back toward the rear bumper 21 so that the overlapping portion 34 of the lining 27 enters the rear side of the flange portion 31 of the side extension portion 21a. At this time, as shown in FIG. 10B, the rib 38 with which the edge of the flange portion 31 is in sliding contact functions as a guide for moving over the overlapping portion 34 relatively, and the flange portion 31 smoothly and properly overlaps. Can be overcome. This position is a position where an operator who attaches a bumper from the rear side of the vehicle can easily work by extending his hand, and the rib 38 is formed so that the work can be performed with one hand. Productivity is greatly improved.

  When the flange portion 31 gets over the overlapping portion 34, the lining 27 is restored to its original shape due to its elasticity, and the flange portion 31 enters between the fixing portion 33 and the overlapping portion 34. The fixing portion 33 is fixed to the flange portion 31 with a screw (a plate-like nut (referred to as a speed nut or the like) is attached to the flange portion 31 and is screwed to this screw). . Further, the engagement hole 31a of the flange portion 31 and the engagement hole 33a of the fixing portion 33 are aligned (FIG. 10C) and fixed to each other by the clip 26D. Further, the engagement hole 32a of the rear bumper 21 and the engagement hole 37a of the lining 27 are aligned, the clip 26E is inserted, and further fixed to the body 11 which is the peripheral end of the rear wheel house 22.

  In the lining structure of the present invention, as described above, the lining 27 is provided with the fixing portion 33 that comes into contact with the front side (the tire side) of the flange portion 31 of the rear bumper 21 and the overlapping portion 34 that overlaps the back side. Insert between them. Thus, for example, as shown in FIG. 8 and the like, the lining 27 is positioned on the back side of the flange portion 31 of the rear bumper 21 so that the end portion of the lining 27 cannot be seen from the outside of the vehicle. Therefore, the appearance around the both sides of the rear bumper 21 is improved, and the merchantability is greatly improved.

  Further, by holding the flange portion 31 of the rear bumper 21 between the fixing portion 33 and the overlapping portion 34 of the lining 27, the relatively flexible lining 27 can be reinforced by the rear bumper 21. Further, by positioning the lining 27, an accurate overlapping structure in which a gap is hardly generated is realized. By eliminating the gap, it is possible to suppress the intrusion of muddy water or the like from the tire into the gap and to prevent the muddy water or the like from seeping out from the gap in the rear bumper 21 at the rear of the vehicle.

  In addition, the lining 27 is provided with a rib 38 reaching the vehicle side end on the back side of the overlapping portion 34. By providing the ribs 38 to the side end portions, the flange portion 31 of the rear bumper 21 is not caught on the overlap portion 34 during assembly, and the overlap portion 34 can be easily and smoothly climbed over. Thus, the rib 38 performs the guide function, so that the assembling property is greatly improved and the assembling can be surely performed, so that the assembling failure such as the wrong assembling is prevented. The rib 38 also has a reinforcing effect around the overlapping portion 34 and can increase the rigidity after assembly, which is extremely effective particularly in the lining 27 formed of a relatively soft material. In the embodiment of the present invention, since the lining 27 is located behind the wheel, durability from the wheel to the stepping stones by traveling is improved.

  Further, in the lining 27, the fixing portion 33 is provided below the overlapping portion 34, and the rib 38 is provided at the lower end portion of the overlapping portion 34. Since the rib 38 is provided in the vicinity of the fixing portion 33, the flange portion 31 of the rear bumper 21 to which the fixing portion 33 is fixed can reliably get over the overlapping portion 34. Further, since the fixing portion 33 is provided below, the overlapping portion 34 can be reliably overlapped with the flange portion 31.

  Further, the flange portion 31 of the rear bumper 21 is formed wider in the vicinity of the fixing portion 33 of the lining 27, and further narrowed toward the upper end portion. The upper and lower ends of the rear bumper 21 and the lining 27 that are overlapped with each other are fixed to form a fixing structure in which a gap is hardly generated, and the moldability of the rear bumper 21 can be improved. Further, by narrowing the vicinity of the upper end of the flange portion 31, it is possible to avoid interference with the bumper holder 39 of the rear bumper 21 at the time of assembly, and to improve the assemblability.

As mentioned above, although this invention was demonstrated with embodiment, this invention is not limited only to these embodiment, A change etc. are possible within the scope of the present invention.
For example, it may be a front bumper instead of a rear bumper, and the rib 38 provided on the lining may have a taper shape or the like in addition to a curved shape, and the number thereof is not limited to the case of the illustrated example. It can be increased or decreased as appropriate.
In addition, the lining structure of the present invention has an excellent effect in assembling parts having a sandwiching structure when attaching aero parts or the like to the bumper, for example, in attaching the trim to the trim.
