前述のように、図１０〜図１２に示したフェンダパネル１０９の取付構造においては、フェンダパネル１０９に形成された第２取付孔１１１は不図示のバンパホルダを取り付けるための不図示のボルトが挿通するためのものであるが、第１取付孔１１０と第２取付孔１１１は隣接して形成されていることと、同じねじサイズのナットを使用しているために、組付工程において図１１及び図１２に示すようにフェンダ締付ボルト１１２を誤って第２取付孔１１１に通してフェンダパネル１０９を車体パネル１１３に誤って締付け固定する誤組付が起こり得る。このような場合、図１２に示すように締付固定自体は可能であるため、その後の工程であるフロントバンパホルダの組付工程に至るまで誤組付に気づかず、フロントバンパホルダを適正に組み付けることができないという問題が発生する。この問題は、第１取付孔１１０部分の締付固定作業と第２取付孔１１１部分の締付固定作業の間に車体の塗装工程がある場合、車体の錆対策に対して重要な問題となる。 As described above, in the mounting structure of the fender panel 109 shown in FIGS. 10 to 12, a bolt (not shown) for attaching a bumper holder (not shown) is inserted into the second mounting hole 111 formed in the fender panel 109. For this reason, the first mounting hole 110 and the second mounting hole 111 are formed adjacent to each other, and a nut having the same screw size is used. As shown in FIG. 12, there is a possibility that the fender tightening bolt 112 is erroneously passed through the second mounting hole 111 and the fender panel 109 is erroneously tightened and fixed to the vehicle body panel 113. In such a case, as shown in FIG. 12, the fastening and fixing itself is possible, so that the front bumper holder is properly assembled without noticing the incorrect assembly until the subsequent assembly process of the front bumper holder. The problem of not being able to occur. This problem becomes an important problem for rust prevention of the vehicle body when there is a vehicle body painting process between the tightening and fixing operation of the first mounting hole 110 portion and the tightening and fixing operation of the second mounting hole 111 portion. .

本発明は上記問題に鑑みてなされたもので、その目的とする処は、フェンダパネルの誤組付を容易に発見でき、誤組付を確実に防ぐことができるフェンダパネルの取付構造を提供することにある。 The present invention has been made in view of the above problems, and an object of the present invention is to provide a fender panel mounting structure that can easily detect a fender panel misassembly and reliably prevent the misassembly. There is.

上記目的を達成するため、請求項１記載の発明は、端縁部に近接して形成された複数の取付孔の少なくとも１つに挿通する締結部材によって車体に取り付けられるフェンダパネルの車体への取付構造として、複数の前記取付孔には、前記締結部材の頭部の径寸法よりも小さな直径の第１取付孔と、前記締結部材の頭部の径寸法よりも大きな直径の第２取付孔が含まれ、前記第１取付孔に挿通する締結部材によってフェンダパネルを車体に取り付ける構成を採用したことを特徴とする。 In order to achieve the above object, according to the first aspect of the present invention, there is provided an attachment to a vehicle body of a fender panel attached to the vehicle body by a fastening member inserted into at least one of a plurality of attachment holes formed close to the edge portion. As a structure, the plurality of mounting holes include a first mounting hole having a diameter smaller than the diameter of the head of the fastening member and a second mounting hole having a diameter larger than the diameter of the head of the fastening member. It is included and the structure which attaches a fender panel to a vehicle body by the fastening member inserted in the said 1st attachment hole is employ | adopted.

請求項２記載の発明は、請求項１記載の発明において、前記第２取付孔よりも先に前記第１取付孔に締結部材を挿通して前記フェンダパネルを車体に取り付けることを特徴とする。 According to a second aspect of the present invention, in the first aspect of the present invention, the fender panel is attached to a vehicle body by inserting a fastening member through the first attachment hole prior to the second attachment hole.

請求項３記載の発明は、請求項１又は２記載の発明において、前記第２取付孔に車体に取り付けられる別部品を重ねて該別部品と車体との間に前記第２取付孔を配置し、第２取付孔に挿通する締結部材によって前記別部品と共に前記フェンダパネルを車体に取り付けることを特徴とする。 According to a third aspect of the present invention, in the first or second aspect of the present invention, the second mounting hole is disposed between the separate part and the vehicle body by stacking another part attached to the vehicle body on the second mounting hole. The fender panel is attached to the vehicle body together with the separate part by a fastening member inserted through the second attachment hole.

請求項４記載の発明は、請求項３記載の発明において、前記別部品を樹脂で構成するとともに、その一部に前記第２取付孔に挿入されるリブを形成したことを特徴とする。 The invention according to claim 4 is the invention according to claim 3, wherein the separate part is made of resin, and a rib inserted into the second attachment hole is formed in a part thereof.

請求項１及び２記載の発明によれば、フェンダパネルの組付工程において作業者が誤って締結部材を第２取付孔に挿通して締め付けても、第２挿通孔の直径は締結部材の頭部の径寸法よりも大きいため、締結部材によってフェンダパネルを車体に取り付け固定することができず、作業者は確実に誤組付に気づくことができる。即ち、取付孔の直径の大小によって締結部材を通すべき取付孔（第１取付孔）を容易に見分けることができるとともに、仮に誤組み付した場合にもフェンダパネルが固定できないため、作業者又は次工程の作業者が容易に異常に気づくことができ、フェンダパネルの誤組付を確実に防ぐことができる。 According to the first and second aspects of the present invention, even if the operator mistakenly inserts and tightens the fastening member into the second mounting hole in the fender panel assembly process, the diameter of the second insertion hole is the head of the fastening member. Since it is larger than the diameter dimension of the part, the fender panel cannot be attached and fixed to the vehicle body by the fastening member, and the operator can be surely aware of the incorrect assembly. That is, the mounting hole (first mounting hole) through which the fastening member should be passed can be easily identified by the size of the mounting hole, and the fender panel cannot be fixed even if it is misassembled. An operator of the process can easily notice the abnormality, and can prevent the fender panel from being erroneously assembled.

請求項３記載の発明によれば、締結部材の頭部の径寸法よりも大きな直径を有する第２取付孔に締結部材を通して別部品を車体に取り付けることはできないが、車体に取り付けられる別部品を重ねて該別部品と車体との間に前記第２取付孔を配置し、別部品の取付孔の直径を締結部材の頭部の径寸法よりも小さくすれば、第２取付孔の周縁を別部品で押さえ込む（車体と挟み込む）ことができるため、第２取付孔に挿通する締結部材を車体に締め付ければ、別部品がフェンダパネルと共に車体に取り付けられる。そして、別部品を取り付けなければ締結部材を締め付けても、該締結部材はその機能を果たさないため、別部品の取り付け忘れをも確実に防ぐことができる。 According to the invention described in claim 3, although another part cannot be attached to the vehicle body through the fastening member through the second attachment hole having a diameter larger than the diameter of the head of the fastening member, If the second mounting hole is arranged between the separate part and the vehicle body and the diameter of the mounting hole of the separate part is made smaller than the diameter of the head of the fastening member, the peripheral edge of the second mounting hole is separated. Since it can be pressed down by a part (sandwiched with the vehicle body), if a fastening member inserted through the second attachment hole is fastened to the vehicle body, another part is attached to the vehicle body together with the fender panel. And even if it fastens a fastening member if another part is not attached, since this fastening member does not fulfill its function, it is possible to reliably prevent forgetting to attach another part.

請求項４記載の発明によれば、別部品の一部に第２取付孔に挿入されるリブを形成したため、フェンダパネルの板厚による締結部材の締結方向の隙間を減少させることができ、別部品の割れや第２取付孔に挿通されてフェンダパネルを締付固定する締結部材の軸力が安定する。 According to invention of Claim 4, since the rib inserted in a 2nd attachment hole was formed in a part of another component, the clearance gap of the fastening direction of the fastening member by the board | plate thickness of a fender panel can be reduced. The axial force of the fastening member that clamps and fixes the fender panel by being cracked in the part or inserted through the second mounting hole is stabilized.

図１に示すように、車両１の左右前後に開口するフロントサイドドア開口２とリヤサイドドア開口３との間には上下方向に延在する左右一対のセンタピラー４がそれぞれ設けられ、該センタピラー４の前後にはフロントピラー５とリヤピラー６がそれぞれ設けられている。そして、車両１の前部にはエンジンルーム７を開閉するフロントフード８が設けられ、車両１の前部の左右両側部には車両の外板であるフェンダバネル９がそれぞれ取り付けられ、これらのフェンダパネル９の前端部には、車両１の前部に車幅方向に配される不図示のフロントバンパが取り付けられる。 As shown in FIG. 1, a pair of left and right center pillars 4 extending in the vertical direction are provided between a front side door opening 2 and a rear side door opening 3 that open to the left and right and front and rear of the vehicle 1, respectively. A front pillar 5 and a rear pillar 6 are respectively provided before and after 4. A front hood 8 that opens and closes the engine room 7 is provided at the front portion of the vehicle 1, and fender panel 9 that is an outer plate of the vehicle is attached to both the left and right sides of the front portion of the vehicle 1. A front bumper (not shown) disposed in the vehicle width direction is attached to the front end of the panel 9 at the front end of the vehicle 9.

ところで、図２に示すように、各フェンダパネル９の前端部にはフランジ状の取付部９ａが形成されており、この取付部９ａには長孔状の第１取付孔１０と円孔状の第２取付孔１１が近接して形成されている。そして、これらの第１取付孔１０と第２取付孔１１にボルトを挿入して車体パネル１３に溶着されたナット１８にねじ込むことによって、フェンダパネル９の前端部に形成された取付部９ａを車体パネル１３に締付け固定している。尚、当該ナット１８は生産性向上のために第１取付孔１０と第２取付孔１１の締付け固定用に同じ寸法のナットが使用されている。 By the way, as shown in FIG. 2, a flange-like attachment portion 9a is formed at the front end of each fender panel 9, and the attachment portion 9a has a first attachment hole 10 having a long hole shape and a circular hole-like attachment portion 9a. A second mounting hole 11 is formed in close proximity. A bolt is inserted into the first mounting hole 10 and the second mounting hole 11 and screwed into a nut 18 welded to the vehicle body panel 13, thereby attaching the mounting portion 9 a formed at the front end of the fender panel 9 to the vehicle body. The panel 13 is fastened and fixed. Note that the nut 18 has the same size for tightening and fixing the first mounting hole 10 and the second mounting hole 11 in order to improve productivity.

ここで、第１取付孔１０には図３に示すようにフェンダ締付ボルト１２（図６参照）が通され、このフェンダ締付ボルト１２によってフェンダパネル９の前端部が車体パネル１３（図９参照）に締付固定され、第２取付孔１１には図３及び図４に示すようにバンパホルダ締付ボルト１４が通され、このバンパホルダ締付ボルト１４によってバンパホルダ１５を車体パネル１３に締付固定するのと同時にバンパホルダ１５と車体パネル１３の間にフェンダパネル９の取付部９ａを挟み込んで締付固定される。 Here, as shown in FIG. 3, a fender fastening bolt 12 (see FIG. 6) is passed through the first mounting hole 10, and the front end portion of the fender panel 9 is connected to the vehicle body panel 13 (FIG. 9) by the fender fastening bolt 12. The bumper holder tightening bolt 14 is passed through the second mounting hole 11 as shown in FIGS. 3 and 4, and the bumper holder tightening bolt 14 fastens and fixes the bumper holder 15 to the vehicle body panel 13. At the same time, the mounting portion 9a of the fender panel 9 is sandwiched between the bumper holder 15 and the vehicle body panel 13 and fastened and fixed.

而して、本実施の形態では、フェンダパネル９の取付部９ａに形成された第１取付孔１０の直径（最小直径）ｄ１（図２参照）は図６に示すフェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１（図６（ｂ）参照）よりも小さく設定され（ｄ１＜Ｄ１）、第２取付孔１１の直径ｄ２はフェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きく（ｄ２＞Ｄ１）設定されている（図９参照）。 Thus, in the present embodiment, the diameter (minimum diameter) d1 (see FIG. 2) of the first mounting hole 10 formed in the mounting portion 9a of the fender panel 9 is the head of the fender fastening bolt 12 shown in FIG. The diameter d2 of the second mounting hole 11 is set larger than the diameter dimension D1 of the head 12a of the fender fastening bolt 12 (d1 <D1). (D2> D1) is set (see FIG. 9).

又、バンパホルダ１５は、不図示のフロントバンパをフェンダパネル９の先端部に取り付けるための樹脂製部品であって、図５に示すように、その背面側（車両へ取り付けた状態で車体パネル１３側）には車体パネル１３への締付固定部となる円筒状のボス１５Ａが一体に突設されている。そして、このボス１５Ａの背面側に形成され後述するバンパホルダ締付ボルト１４の締付座面となる底壁１５ａの中心にはバンパホルダ締付ボルト１４が挿通される円穴１６が形成されており、底壁１５ａの円孔１６の周囲には、図４に示すように、該バンパホルダ１５をフェンダパネル９と共に車体パネル１３に取り付けた状態で、フェンダパネル９の取付部９ａに形成された大径の第２取付孔１１に挿入されるリング状のリブ１５ｂが一体に突設されている。 The bumper holder 15 is a resin part for attaching a front bumper (not shown) to the tip of the fender panel 9, and as shown in FIG. 5, the rear side (the body panel 13 side when attached to the vehicle). ) Is integrally provided with a cylindrical boss 15A serving as a fastening portion for fastening to the vehicle body panel 13. A circular hole 16 through which the bumper holder fastening bolt 14 is inserted is formed at the center of the bottom wall 15a formed on the back side of the boss 15A and serving as a fastening seat surface of a bumper holder fastening bolt 14 described later. As shown in FIG. 4, the bumper holder 15 is attached to the vehicle body panel 13 together with the fender panel 9 around the circular hole 16 of the bottom wall 15 a, and has a large diameter formed on the attachment portion 9 a of the fender panel 9. A ring-shaped rib 15b inserted into the second mounting hole 11 is integrally projected.

而して、図４に示すように、バンパホルダ１５は、これに突設されたボス１５Ａとその底壁１５ａに形成された円孔１６に通されたバンパホルダ締付ボルト１４（形状の詳細は図７参照）をフェンダパネル９の第２取付孔１１及び車体パネル１３に形成された円孔１７に通し、バンパホルダ締付ボルト１４を車体パネル１３の内面（車両中央側の面）の円孔１７の周囲に溶着されたナット１８にねじ込むことによって、車体パネル１３に取り付けられる。このとき、バンパホルダ１５は、フェンダパネル９の取付部９ａを車体パネル１３との間で挟持する状態で締付固定されるため、フェンダパネル９の取付部９ａも同時に車体パネル１３に締付固定される。 Thus, as shown in FIG. 4, the bumper holder 15 includes a bumper holder fastening bolt 14 (details of the shape are shown in FIG. 4) passed through a boss 15A projecting from the bumper holder 15 and a circular hole 16 formed in the bottom wall 15a. 7) is passed through the second mounting hole 11 of the fender panel 9 and the circular hole 17 formed in the vehicle body panel 13, and the bumper holder fastening bolt 14 is inserted into the circular hole 17 on the inner surface of the vehicle body panel 13 (the surface on the vehicle center side). It is attached to the vehicle body panel 13 by screwing into the nut 18 welded to the periphery. At this time, the bumper holder 15 is fastened and fixed in a state where the mounting portion 9a of the fender panel 9 is sandwiched between the bumper holder 9 and the vehicle body panel 13, so that the mounting portion 9a of the fender panel 9 is also fastened and fixed to the vehicle body panel 13 at the same time. The

ここで、バンパホルダ１５のボス１５Ａの底壁１５ａに形成された円孔１６の直径ｄ３はバンパホルダ締付ボルト１４に挿通するワッシャ１９の外径Ｄ２よりも小さく設定され（ｄ３＜Ｄ２）、リブ１５ｂの端面と車体パネル１３との間には所定の隙間δが形成されている。従って、図４に示すように、円孔１６及びフェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きな直径ｄ２（＞Ｄ１）の第２取付孔１１に通されたバンパホルダ締付ボルト１４をナット１８にねじ込めば、バンパホルダ１５がフェンダパネル９を車体パネル１３とで挟持する状態となり、フェンダパネル９の取付部９ａを車体パネル１３に締付固定することができる。 Here, the diameter d3 of the circular hole 16 formed in the bottom wall 15a of the boss 15A of the bumper holder 15 is set smaller than the outer diameter D2 of the washer 19 inserted through the bumper holder clamping bolt 14 (d3 <D2), and the rib 15b. A predetermined gap δ is formed between the end face of the vehicle body and the vehicle body panel 13. Therefore, as shown in FIG. 4, the bumper holder clamping bolt 14 passed through the second mounting hole 11 having a diameter d2 (> D1) larger than the diameter D1 of the circular hole 16 and the head 12a of the fender clamping bolt 12. Is screwed into the nut 18, the bumper holder 15 is in a state of sandwiching the fender panel 9 with the vehicle body panel 13, and the mounting portion 9 a of the fender panel 9 can be fastened and fixed to the vehicle body panel 13.

ところで、作業者がフェンダパネル９の取付部９ａに互いに隣接して形成された第１取付孔１０と第２取付孔１１を区別できないまま、図８及び図９に示すように、フェンダ締付ボルト１２を誤って第２取付孔１１に通して車体パネル１３の内面に溶着されたナット１８にねじ込んでしまった場合、前述のように第２取付孔１１の直径ｄ２はフェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きく設定されているため（ｄ２＞Ｄ１）、フェンダ締付ボルト１２をナット１８に締め付けてもフェンダパネル９を車体パネル１３に取り付けることができず、フェンダパネル９の先端部がガタつくために作業者は誤組付に容易に気づき、フェンダ締付ボルト１２を本来の第１取付孔１０に正しく通し、このフェンダ締付ボルト１２によってフェンダパネル９を車体パネル１３に正しく付け直すことができる。 By the way, as shown in FIG. 8 and FIG. 9, the fender fastening bolts are provided without allowing the operator to distinguish between the first mounting hole 10 and the second mounting hole 11 formed adjacent to each other on the mounting portion 9 a of the fender panel 9. 12 is accidentally passed through the second mounting hole 11 and screwed into the nut 18 welded to the inner surface of the vehicle body panel 13, the diameter d2 of the second mounting hole 11 is the head of the fender fastening bolt 12 as described above. Since the diameter D1 of the portion 12a is set to be larger (d2> D1), the fender panel 9 cannot be attached to the vehicle body panel 13 even if the fender fastening bolt 12 is fastened to the nut 18, and the fender panel 9 Since the tip part is rattled, the operator easily notices the wrong assembly, and the fender fastening bolt 12 is correctly passed through the original first mounting hole 10, and the fender fastening bolt 12 The Endapaneru 9 can be re-attached properly to the vehicle body panel 13.

実際の製造工程においては、フェンダパネル９をフェンダ締付ボルト１２によって車体パネル１３に取り付けた後に車体を電着塗装するため、フェンダ締付ボルト１２及びフェンダパネル９のフェンダ締付ボルト１２による締付箇所も電着塗装される。そして、その後の工程においてバンパホルダ１５をバンパホルダ締付ボルト１４によってフェンダパネル９と車体パネル１３に取り付け、このバンパホルダ１５にフロントバンパが取り付けられる。 In the actual manufacturing process, after the fender panel 9 is attached to the vehicle body panel 13 with the fender fastening bolts 12, the vehicle body is electrodeposited, so that the fender fastening bolts 12 and the fender panel 9 are fastened with the fender fastening bolts 12. The places are also electrodeposited. In the subsequent process, the bumper holder 15 is attached to the fender panel 9 and the vehicle body panel 13 by the bumper holder fastening bolts 14, and the front bumper is attached to the bumper holder 15.

従って、作業者が誤ってフェンダ締付ボルト１２を第２取付孔１１に通してフェンダパネル９を車体パネル１３に取り付けたまま塗装がなされ、その後に誤組付けが発見されて付け直す場合には、その部分の塗装が剥がれて錆発生の原因になる虞がある。然るに、本発明によれば、作業者は誤組付に容易に気づくため、誤組付がなされたまま電着塗装がなされることがなく、塗装後にフェンダ締付ボルト１２を第２取付孔１１から取り外して取り付け直す事態の発生が防がれ、塗装が剥れる等の不具合が発生することがない。 Therefore, when an operator accidentally passes the fender tightening bolt 12 through the second mounting hole 11 and paints with the fender panel 9 attached to the vehicle body panel 13, and then finds that the wrong assembly has been found and reinstalls it. There is a possibility that the coating of the part is peeled off and rust is generated. However, according to the present invention, since the operator easily notices the incorrect assembly, the electrodeposition coating is not performed while the erroneous assembly is performed, and the fender tightening bolt 12 is attached to the second mounting hole 11 after the coating. Occurrence of a situation where it is removed and reattached is prevented, and problems such as peeling of the paint do not occur.

以上のように、本実施の形態では、フェンダパネル９の組付工程において作業者が誤ってフェンダ締付ボルト１２を第２取付孔１１に挿通して締め付けても、第２取付孔１１の直径ｄ２はフェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きいため（ｄ２＞Ｄ１）、フェンダ締付ボルト１２によってフェンダパネル９を車体パネル１３に取り付けることができず、フェンダパネル９がガタつくために作業者は誤組付に容易に気づくことができる。即ち、第１取付孔１０の直径ｄ１と第２取付孔１１の直径ｄ２の大小によってフェンダ締付ボルト１２を通すべき第１取付孔１０を容易に見分けることができるとともに、仮に誤組み付けした場合にもフェンダパネルが固定できないため、作業者又は次工程の作業者が容易に異常に気づくことができ、フェンダパネル９の誤組付を確実に防ぐことができる。 As described above, in the present embodiment, even if an operator mistakenly inserts and tightens the fender tightening bolt 12 into the second mounting hole 11 in the assembly process of the fender panel 9, the diameter of the second mounting hole 11 is increased. Since d2 is larger than the diameter dimension D1 of the head 12a of the fender fastening bolt 12 (d2> D1), the fender panel 9 cannot be attached to the vehicle body panel 13 by the fender fastening bolt 12, and the fender panel 9 is loose. To turn on, the operator can easily notice the wrong assembly. That is, the first mounting hole 10 through which the fender fastening bolt 12 should be passed can be easily identified by the size of the diameter d1 of the first mounting hole 10 and the diameter d2 of the second mounting hole 11, and if it is misassembled. In addition, since the fender panel cannot be fixed, the worker or the worker in the next process can easily notice the abnormality, and the fender panel 9 can be reliably prevented from being assembled.

又、本実施の形態では、フェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きな直径ｄ２（＞Ｄ１）を有する第２取付孔１１にフェンダ締付ボルト１２を利用してフェンダパネル９を車体パネル１３に締付固定することはできないが、図４に示すように、バンパホルダ１５を取り付けることでフェンダパネル９を車体パネル１３に取り付けることができる。つまり、フェンダ締付ボルト１２の頭部１２ａの径寸法Ｄ１よりも大きな直径ｄ２（＞Ｄ１）の第２取付孔１１及びバンパホルダ１５のボス１５Ａの底壁１５ａに形成された円孔１６に通されたバンパホルダ締付ボルト１４をナット１８にねじ込んでバンパホルダ１５を車体パネル１３に取り付ければ、バンパホルダ１５がフェンダパネル９を車体パネル１３とで挟持する状態となり、フェンダパネル９の取付部９ａを車体パネル１３に取り付けることができる。この場合、バンパホルダ１５を取り付けなければバンパホルダ締付ボルト１４を締め付けても、該バンパホルダ１５はその機能を果たさないため、バンパホルダ１５の取り付け忘れを確実に防ぐことができる。 Further, in the present embodiment, the fender panel 9 using the fender fastening bolt 12 in the second mounting hole 11 having a diameter d2 (> D1) larger than the diameter D1 of the head 12a of the fender fastening bolt 12 is used. Cannot be fastened and fixed to the vehicle body panel 13, but the fender panel 9 can be attached to the vehicle body panel 13 by attaching the bumper holder 15 as shown in FIG. That is, it passes through the second mounting hole 11 having a diameter d2 (> D1) larger than the diameter D1 of the head 12a of the fender fastening bolt 12 and the circular hole 16 formed in the bottom wall 15a of the boss 15A of the bumper holder 15. If the bumper holder clamping bolt 14 is screwed into the nut 18 and the bumper holder 15 is attached to the vehicle body panel 13, the bumper holder 15 is in a state of sandwiching the fender panel 9 with the vehicle body panel 13. Can be attached to. In this case, even if the bumper holder fastening bolt 14 is tightened unless the bumper holder 15 is attached, the bumper holder 15 does not perform its function, so that it is possible to reliably prevent forgetting to install the bumper holder 15.

更に、本実施の形態では、バンパホルダ１５に突設されたボス１５Ａの底壁１５ａにリング状のリブ１５ｂを突設し、バンパホルダ１５の取り付けに際してリブ１５ｂを第２取付孔１１に挿入するようにしたため、フェンダパネル９の板厚によるバンパホルダ締付ボルト１４の締結方向の隙間を減少させることができ、ボルトの締め付けによるバンパホルダ１５の割れが防止でき、第２取付孔１１に挿通するバンパホルダ締付ボルト１４の軸力が安定するという効果も得られる。これは、バンパホルダ締付ボルト１４に挿通するワッシャ１９の外径Ｄ２が第２取付孔１１の直径ｄ２よりも小さい（ｄ２＞Ｄ２）場合に特に有効となり、更にフェンダパネル９の締付ワッシャ１９の外径Ｄ２を小さくすることが可能となる。 Further, in the present embodiment, a ring-shaped rib 15b is projected from the bottom wall 15a of the boss 15A projecting from the bumper holder 15, and the rib 15b is inserted into the second mounting hole 11 when the bumper holder 15 is mounted. Therefore, the gap in the fastening direction of the bumper holder fastening bolt 14 due to the thickness of the fender panel 9 can be reduced, the bumper holder 15 can be prevented from cracking due to the bolt fastening, and the bumper holder fastening bolt inserted through the second mounting hole 11. The effect that the axial force of 14 is stabilized is also acquired. This is particularly effective when the outer diameter D2 of the washer 19 inserted through the bumper holder clamping bolt 14 is smaller than the diameter d2 of the second mounting hole 11 (d2> D2). Further, the clamping washer 19 of the fender panel 9 is further effective. The outer diameter D2 can be reduced.
