The clip insertion holes 31 of the cap upper plate portion 27 and the cap lower plate portion 28 are inserted into the space inside the cap 13 with the vehicle width direction outer ends of the first member 11 and the second member 12 inserted. It is formed at a position communicating with the clip insertion hole 18 of the upper plate portion 15 and the lower plate portion 16 . The cap 13 is formed by inserting the clip 32 into the clip insertion holes 18 and 31 in a state in which the vehicle width direction outer ends of the first member 11 and the second member 12 are inserted into the space inside the cap 13 . 11 in the vehicle width direction. With the cap 13 attached to the vehicle width direction outer end of the first member 11 , the vehicle width direction inner end edge 33 of the cap rear plate portion 30 is positioned further than the vehicle width direction outer end edge 22 of the second member 12 . The length of the cap 13 in the vehicle width direction is set so as to be located on the inner side in the vehicle width direction. The cap 13 closes the internal space 14 of the FUP 10 from the outside in the vehicle width direction while covering the corners (edges) of the vehicle width direction outer edges 23 and 22 of the first member 11 and the second member 12 .

上記のように構成されたＦＵＰ１０では、第１部材１１の上下のクリップ挿通孔１８は、第１部材１１の上板部１５及び下板部１６のうち、第２部材１２の上板部１９及び下板部２０の車幅方向外端縁２２よりも車幅方向外側へ突出する領域２４に形成される。すなわち、クリップ挿通孔１８は、第１部材１１の上板部１５及び下板部１６のうち、第２部材１２の上板部１９及び下板部２０と重ならない領域２４に形成される。このため、第１部材１１の上板部１５及び下板部１６と、第２部材１２の上板部１９及び下板部２０とが重なった領域にクリップ挿通孔を形成する場合と比べ、容易にクリップ挿通孔１８を形成することができるので、キャップ１３の取付作業の作業性を向上させることができる。 In the FUP 10 configured as described above, the upper and lower clip insertion holes 18 of the first member 11 are the upper plate portion 19 and the upper plate portion 19 of the second member 12 of the upper plate portion 15 and the lower plate portion 16 of the first member 11 . It is formed in a region 24 that protrudes outward in the vehicle width direction from the outer edge 22 in the vehicle width direction of the lower plate portion 20 . That is, the clip insertion hole 18 is formed in a region 24 of the upper plate portion 15 and the lower plate portion 16 of the first member 11 that do not overlap the upper plate portion 19 and the lower plate portion 20 of the second member 12 . For this reason, compared with the case where the clip insertion hole is formed in the region where the upper plate portion 15 and the lower plate portion 16 of the first member 11 and the upper plate portion 19 and the lower plate portion 20 of the second member 12 are overlapped, it is easier to remove the clip. Since the clip insertion hole 18 can be formed in the hole 18, the workability of attaching the cap 13 can be improved.

また、第１部材１１が前側に配置され、第２部材１２が第１部材１１の後側に配置され、第２部材１２の車幅方向の長さが第１部材１１よりも短い。すなわち、車幅方向に長い方の部材である第１部材１１を前側に配置しているので、車両１を前方から視た際に、短い方の部材である第２部材１２が見え難くなり、ＦＵＰ１０の見栄えの低下を抑えることができる。 Also, the first member 11 is arranged on the front side, the second member 12 is arranged on the rear side of the first member 11 , and the length of the second member 12 in the vehicle width direction is shorter than that of the first member 11 . That is, since the first member 11, which is the longer member in the vehicle width direction, is arranged on the front side, the second member 12, which is the shorter member, is less visible when the vehicle 1 is viewed from the front. A deterioration in appearance of the FUP 10 can be suppressed.
