[0002]
[Prior art]
In general, a bumper cover is fixed to a front end portion and a rear end portion of a vehicle body of an automobile in a state substantially parallel to the vehicle width direction. Here, as an example, a front bumper cover provided at a front end portion of a vehicle body (not shown) will be described with reference to FIGS. 4 and 5. The front bumper cover 100 is assembled by fixing the plurality of locations to the vehicle body using screws or clips. In particular, the upper edge portion of the front bumper cover 100 is fixed to the vehicle body via the lean reinforcement 110. Depending on the vehicle type, when the front bumper cover 100 is assembled to the lean reinforcement 110 after the lean reinforcement 110 is assembled to the vehicle body, and before the lean reinforcement 110 is assembled to the vehicle body, the front bumper cover 100 is assembled to the lean reinforcement 110. There are cases.
[0003]
The front bumper cover 100 is integrally formed of a resin material, has a substantially rectangular shape extending in the vehicle width direction in a front view, and is curved in a vehicle width direction portion 100a that is curved so as to protrude in the front direction of the vehicle body in a plan view. The vehicle width direction portion 100a includes a pair of front and rear direction portions 100b and 100b extending substantially in parallel with the front and rear direction of the vehicle body from both ends in the longitudinal direction toward the rear of the vehicle body. A flange 105 for assembling the front bumper cover 100 to the lean reinforcement 110 protrudes from the rear surface of the vehicle width direction portion 100a toward the rear side of the vehicle body. In the flange 105, five clip insertion holes 107 into which clips 140 for fixing the self and the lean reinforcement 110 are inserted are equally drilled in the length direction.
[0004]
The lean reinforcement 110 is formed by bending a single metal plate having a predetermined thickness. Specifically, the lean reinforcement 110 has a substantially rectangular shape that is substantially perpendicular to the vertical direction, has the same length in the vehicle width direction as the flange 105, and is curved so as to protrude forward in the vehicle body in plan view. An upper horizontal wall 110a having a shape, a front vertical wall 110b and a rear vertical wall 110c extending downward from the side edge of the upper horizontal wall 110a in the longitudinal direction of the vehicle body so as to be substantially perpendicular to the upper horizontal wall 110a. A front horizontal wall 110d extending in the front direction of the vehicle body from the lower edge of the vertical wall 110b to be substantially parallel to the upper horizontal wall 110a, and substantially parallel to the upper horizontal wall 110a from the lower edge of the rear vertical wall 110c. Thus, the rear horizontal wall 110e extending in the rearward direction of the vehicle body is formed, and the cross section is a hat type with a border, that is, a hat type. Further, five clip insertion holes 113 are equally drilled in the length direction in the upper horizontal wall 110a corresponding to the clip insertion holes 107 drilled in the flange 105.
[0005]
When the front bumper cover 100 is assembled to the lean reinforcement 110 after the lean reinforcement 110 is assembled to the vehicle body, the front bumper cover 100 is lifted by hand, and the front bumper cover 100 is assembled before the lean reinforcement 110 is assembled to the vehicle body. When assembling 100 to the lean reinforcement 110, the lean reinforcement 110 is lifted by hand, and the flange 105 is placed on the upper horizontal wall 110a of the lean reinforcement 110 and the clip insertion hole 107 and the clip insertion formed in each member. The front bumper cover 100 is assembled to the lean reinforcement 110 by overlapping the holes 113 so as to be positioned on the same axis and inserting the clips 140 into the respective clip insertion holes. At this time, the clip 140 is inserted into the clip insertion holes 107 and 113 that are vertically stacked while the body portion 140b is bent in the axial direction, and pushed into the back until the head portion 140a contacts the flange 105. The front bumper cover 100 and the lean reinforcement 110 are sandwiched between the head portion 140a and the body portion 140b from which the bending is eliminated. Further, a headlamp 130 and the like are disposed above the front bumper cover 100 fixed to the vehicle body.
[0006]
[Problems to be solved by the invention]
However, in the above-described prior art, the bumper cover 100 and the lean reinforcement 110 are large members. Therefore, while the bumper cover 100 or the lean reinforcement 110 is lifted by hand, the bumper cover 100 and the lean reinforcement 110 are each clipped. There is a problem that it is difficult to overlap the insertion holes 107 and 113 so that the positions of the insertion holes 107 and 113 are aligned.
