　後面板部４１４は、金属製で、長方形状の領域を有する。後面板部４１４の長手方向は、車両の車幅方向と同じ方向である。後面板部４１４は、上面板部４１２及び下面板部４１３の車両の前後方向における後端間に、それぞれ湾曲部を介して設けられている。後面板部４１４は、上面板部４１２及び下面板部４１３と直交して形成されている。 The rear plate portion 414 is made of metal and has a rectangular area. The longitudinal direction of the rear plate portion 414 is the same direction as the vehicle width direction of the vehicle. The rear surface plate portion 414 is provided between the rear ends of the upper surface plate portion 412 and the lower surface plate portion 413 in the vehicle front-rear direction via curved portions. The rear plate portion 414 is formed orthogonal to the upper plate portion 412 and the lower plate portion 413.
　左側面板部４１５は、金属製で、長方形状の領域を有する。左側面板部４１５は、前面板部４１１、上面板部４１２、下面板部４１３、及び後面板部４１４の車両の車幅方向における左端に設けられている。右側面板部４１６は、金属製で、長方形状の領域を有する。右側面板部４１６は、前面板部４１１、上面板部４１２、下面板部４１３、及び後面板部４１４の車両の車幅方向における右端に設けられている。 The left side plate portion 415 is made of metal and has a rectangular area. The left side plate portion 415 is provided at the left end of the front plate portion 411, the upper plate portion 412, the lower plate portion 413, and the rear plate portion 414 in the vehicle width direction of the vehicle.

The right side plate 416 is provided at the right end of the front plate 411, the upper plate 412, the lower plate 413, and the rear plate 414 in the vehicle width direction of the vehicle.
　第１ブラケット４２は、フロントアンダーランプロテクタ４１をブラケット３に取付けるための取付部材である。第１ブラケット４２は、金属製で、断面がＬ字形状を有する。第１ブラケット４２は、縦板部４２１と横板部４２２とを有する。 The first bracket 42 is an attachment member for attaching the front underrun protector 41 to the bracket 3. The first bracket 42 is made of metal and has an L-shaped cross section. The first bracket 42 has a vertical plate portion 421 and a horizontal plate portion 422.
　縦板部４２１は、金属製で、略長方形状の領域を有する。縦板部４２１の長手方向は、車両の車幅方向と同じ方向である。横板部４２２は、金属製で、略長方形状の領域を有する。横板部４２２の長手方向は、車両の車幅方向と同じ方向である。横板部４２２は、湾曲部を介して縦板部４２１の車両の高さ方向における下端から、車両の前後方向における前方側に向かって延伸している。横板部４２２は、縦板部４２１と直交している。 The vertical plate portion 421 is made of metal and has a substantially rectangular region. The longitudinal direction of the vertical plate portion 421 is the same direction as the vehicle width direction of the vehicle. The horizontal plate part 422 is made of metal and has a substantially rectangular region. The longitudinal direction of the horizontal plate portion 422 is the same direction as the vehicle width direction of the vehicle. The horizontal plate portion 422 extends from the lower end of the vertical plate portion 421 in the vehicle height direction toward the front side in the vehicle front-rear direction via the curved portion. The horizontal plate portion 422 is orthogonal to the vertical plate portion 421.
　縦板部４２１の一部（縦板部４２１の下方の領域）は、後面板部４１４と溶接部を介して接合されている。縦板部４２１は、縦板部４２１の上方の領域にボルトを挿入するための複数の穴を有する。縦板部４２１の車両の高さ方向における長さは、後面板部４１４の車両の高さ方向における長さよりも大きい。横板部４２２の車両の前後方向における長さは、下面板部４１３の車両の前後方向における長さよりも小さい。横板部４２２は、下面板部４１３と溶接部を介して接合されている。 Part of the vertical plate portion 421 (region below the vertical plate portion 421) is joined to the rear plate portion 414 via a welded portion. The vertical plate portion 421 has a plurality of holes for inserting bolts in the region above the vertical plate portion 421. The length of the vertical plate portion 421 in the vehicle height direction is larger than the length of the rear plate portion 414 in the vehicle height direction. The length of the horizontal plate portion 422 in the front-rear direction of the vehicle is smaller than the length of the lower surface plate portion 413 in the front-rear direction of the vehicle. The horizontal plate portion 422 is joined to the lower surface plate portion 413 through a welded portion.
　このように、縦板部４２１の車両の高さ方向における長さは、フロントアンダーランプロテクタ４１の高さ方向における長さよりも大きく、かつ、横板部４２２の車両の前後方向における長さは、フロントアンダーランプロテクタ４１の車両の前後方向における長さよりも小さい。このような構成であることにより、フロントアンダーランプロテクタ４１の美観を損なわないようにしながら、かつ、フロントアンダーランプロテクタ４１をブラケット３に対して、より強固に固定することができる。 Thus, the length of the vertical plate portion 421 in the vehicle height direction is larger than the length of the front underrun protector 41 in the height direction, and the length of the horizontal plate portion 422 in the vehicle front-rear direction is: The length of the front underrun protector 41 in the longitudinal direction of the vehicle is smaller. With such a configuration, the front under-run protector 41 can be more firmly fixed to the bracket 3 while maintaining the beauty of the front under-run protector 41.
　第２ブラケット４３は、フロントアンダーランプロテクタ４１をブラケット３に取付けるための取付部材である。第２ブラケット４３は、金属製で、断面がＬ字形状を有する。第２ブラケット４３は、縦板部４３１と横板部４３２とを有する。 The second bracket 43 is an attachment member for attaching the front underrun protector 41 to the bracket 3. The second bracket 43 is made of metal and has an L-shaped cross section. The second bracket 43 has a vertical plate portion 431 and a horizontal plate portion 432.
　縦板部４３１は、金属製で、略長方形状の領域を有する。縦板部４３１の長手方向は、車両の車幅方向と同じ方向である。横板部４３２は、金属製で、略長方形状の領域を有する。横板部４３２の長手方向は、車両の車幅方向と同じ方向である。横板部４３２は、湾曲部を介して縦板部４３１の車両の高さ方向における下端から、車両の前後方向における前方側に向かって延伸している。横板部４３２は、縦板部４３１と直交している。 The vertical plate portion 431 is made of metal and has a substantially rectangular region. The longitudinal direction of the vertical plate portion 431 is the same direction as the vehicle width direction of the vehicle. The horizontal plate portion 432 is made of metal and has a substantially rectangular region. The longitudinal direction of the horizontal plate portion 432 is the same direction as the vehicle width direction of the vehicle. The horizontal plate portion 432 extends from the lower end of the vertical plate portion 431 in the vehicle height direction toward the front side in the vehicle front-rear direction via the curved portion. The horizontal plate portion 432 is orthogonal to the vertical plate portion 431.
　このように、縦板部４２１と横板部４２２とは、直交しており、横板部４３２と縦板部４３１とは、直交している。このように第１ブラケット４２は断面がＬ字形状であるので、従来のように第１ブラケット４２の断面がコ字形状である場合よりも、フロントアンダーランプロテクタ４１の上面において溶接される箇所が減少することにより、取付構造４のサイドメンバ１に対する取付精度を向上させることができる。 Thus, the vertical plate portion 421 and the horizontal plate portion 422 are orthogonal to each other, and the horizontal plate portion 432 and the vertical plate portion 431 are orthogonal to each other. As described above, since the first bracket 42 has an L-shaped cross section, the portion to be welded on the upper surface of the front under-run protector 41 is larger than the conventional case where the first bracket 42 has a U-shaped cross section. By reducing, the attachment accuracy with respect to the side member 1 of the attachment structure 4 can be improved.
　縦板部４３１の車両の高さ方向における長さは、縦板部４２１の車両の高さ方向における長さよりも小さい。縦板部４３１は、縦板部４３１の上方の領域にボルトを挿入するための複数の穴を有する。縦板部４３１は、縦板部４２１の一部（縦板部４２１の上方の領域）と溶接部を介して接合されている。縦板部４３１の上端は、縦板部４２１の上端と車両の高さ方向において同じ位置である。このような構成とすることにより、取付構造４をよりコンパクトにすることができる。 The length of the vertical plate portion 431 in the vehicle height direction is smaller than the length of the vertical plate portion 421 in the vehicle height direction. The vertical plate portion 431 has a plurality of holes for inserting bolts in the region above the vertical plate portion 431. The vertical plate portion 431 is joined to a part of the vertical plate portion 421 (region above the vertical plate portion 421) via a welded portion. The upper end of the vertical plate portion 431 is at the same position as the upper end of the vertical plate portion 421 in the vehicle height direction. By setting it as such a structure, the attachment structure 4 can be made more compact.
　横板部４３２の車両の前後方向における長さは、上面板部４１２の車両の前後方向における長さよりも小さい。横板部４３２は、上面板部４１２と溶接部を介して接合されている。また、横板部４３２の車両の前後方向における長さは、横板部４２２の車両の前後方向における長さと等しい。このような構成とすることにより、フロントアンダーランプロテクタ４１における上下の溶接面の長さが等しいので、例えば、振動等によってフロントアンダーランプロテクタ４１にかかる負荷に対してのバランスを良くすることができる。 The length of the horizontal plate portion 432 in the vehicle front-rear direction is smaller than the length of the upper plate portion 412 in the vehicle front-rear direction. The horizontal plate portion 432 is joined to the upper surface plate portion 412 via a welded portion. Further, the length of the horizontal plate portion 432 in the vehicle front-rear direction is equal to the length of the horizontal plate portion 422 in the vehicle front-rear direction. By adopting such a configuration, the lengths of the upper and lower welded surfaces of the front underrun protector 41 are equal to each other. For example, the balance with respect to the load applied to the front underrun protector 41 due to vibration or the like can be improved. .
　また、第１ブラケット４２の車両の車幅方向における長さは、第２ブラケット４３の車両の車幅方向における長さと同じ長さであって、かつ、フロントアンダーランプロテクタ４１の車両の車幅方向における長さよりも小さい。このような構成とすることにより、取付構造４をよりコンパクトにすることができる。 The length of the first bracket 42 in the vehicle width direction of the vehicle is the same as the length of the second bracket 43 in the vehicle width direction of the vehicle, and the vehicle width direction of the vehicle of the front underrun protector 41 is the same. Less than the length in By setting it as such a structure, the attachment structure 4 can be made more compact.
　第１ブラケット４２及び第２ブラケット４３は、第１ブラケット４２及び第２ブラケット４３に形成されている穴と、取付部３２に形成されている穴とに、ボルト４４を挿入し、挿入したボルト４４にナット４５を締結することにより、ブラケット３に対して固定されている。 In the first bracket 42 and the second bracket 43, the bolt 44 is inserted into the hole formed in the first bracket 42 and the second bracket 43 and the hole formed in the attachment portion 32, and the inserted bolt 44 is inserted. The nut 45 is fastened to the bracket 3 by fastening.
［本実施形態に係る取付構造４の製造方法］
　まず、フロントアンダーランプロテクタ４１における下面板部４１３と後面板部４１４とに対して、第１ブラケット４２における横板部４２２と縦板部４２１の下方の領域とを溶接して接合する。 [Method for Manufacturing Mounting Structure 4 According to this Embodiment]
First, the lower plate portion 413 and the rear plate portion 414 in the front underrun protector 41 are welded and joined to the lower plate portion 422 and the lower plate portion 421 in the first bracket 42.
　次に、フロントアンダーランプロテクタ４１における上面板部４１２と第１ブラケット４２における縦板部４２１の上方の領域とに対して、第２ブラケット４３における横板部４３２と縦板部４３１とを溶接して接合することにより、取付構造４が完成する。このような手順で取付構造４を製造することにより、後面板部４１４における縦板部４２１に接する面と、縦板部４３１における縦板部４２１に接する面とが同一平面に位置するので、取付精度が向上するとともに、応力が一部の箇所に集中してしまうことを防止できる。 Next, the horizontal plate portion 432 and the vertical plate portion 431 of the second bracket 43 are welded to the upper surface plate portion 412 of the front underrun protector 41 and the region above the vertical plate portion 421 of the first bracket 42. Thus, the attachment structure 4 is completed. By manufacturing the attachment structure 4 in such a procedure, the surface in contact with the vertical plate portion 421 in the rear plate portion 414 and the surface in contact with the vertical plate portion 421 in the vertical plate portion 431 are located on the same plane. The accuracy can be improved and the stress can be prevented from concentrating on a part.
［本実施形態に係る取付構造４による効果］
　本実施形態に係る取付構造４は、車両の車幅方向に延伸するフロントアンダーランプロテクタ４１と、フロントアンダーランプロテクタ４１の後面と下面とに溶接部を介して固定された第１ブラケット４２と、フロントアンダーランプロテクタ４１の上面と第１ブラケット４２の前面とに溶接部を介して固定された第２ブラケット４３と、を有する。 [Effects of mounting structure 4 according to this embodiment]
The mounting structure 4 according to the present embodiment includes a front underrun protector 41 extending in the vehicle width direction of the vehicle, a first bracket 42 fixed to a rear surface and a bottom surface of the front underrun protector 41 via a welded portion, And a second bracket 43 fixed to the upper surface of the front underrun protector 41 and the front surface of the first bracket 42 via a welded portion.
　本実施形態に係る取付構造４は、このような構成を有することにより、フロントアンダーランプロテクタ４１の上面に対して、複数のブラケットが重なって溶接により接合されている構成がなくなり、フロントアンダーランプロテクタ４１の上面に対して、１つのブラケット（第２ブラケット４３）が接合されている構成となる。この結果、取付構造４のサイドメンバ１に対する取付精度を向上させることができる。 Since the mounting structure 4 according to this embodiment has such a configuration, there is no configuration in which a plurality of brackets are overlapped and joined to the upper surface of the front underrun protector 41 by welding, and the front underrun protector is eliminated. One bracket (second bracket 43) is joined to the upper surface of 41. As a result, the mounting accuracy with respect to the side member 1 of the mounting structure 4 can be improved.
