Abstract
Description
一般的にリアストレーキやリアインナフェンダは、樹脂部品で成形される。これらの樹脂部品を介して車体にボルト締結する場合、ボルトの締め付けトルクを大きくすると樹脂部品の潰れが発生したり、樹脂部品であるリアストレーキやリアインナフェンダが熱伸び変形して板厚が変わり、これによりボルトの締め付けトルクが安定しない又は締め付けトルクが不足する等の課題があった。
例えば、ボルトの締め付けトルクが不足した場合、リアインナフェンダの内側の車体部品であるリアホイルハウスインナ、リアホイルハウスアウタや、ホイルハウス前方のサイドシルの締結力が低下し、車体剛性及び強度が低下するという課題があった。
前記ホイルハウスの前記タイヤに向く側の面を覆うインナフェンダと、前記ホイルハウスに設けられたホイルハウス側締結穴に対して前記インナフェンダを介してボルト締結されるストレーキと、を備え、前記ストレーキは、前記ホイルハウス側締結穴に対して前記インナフェンダを介して取り付けるための取付部と、前記取付部から前記ホイルハウス側に向かって所定突出量で突出し、ボルトの頭部を収容可能なボルト締結面部と、前記ボルト締結面部に形成されたボルト貫通穴と、を備え、前記インナフェンダは、前記ボルト締結面部に対応する位置に前記ボルト締結面部よりも大径の切欠き部を備え、前記ボルトは、前記ホイルハウス側締結穴に螺着するネジ部と、前記ネジ部よりも大径で且つ前記ボルト貫通穴よりも小径の前記頭部と、前記ボルト貫通穴よりも大径で且つ前記ボルト締結面部よりも小径のつば部と、を軸方向にこの順番に備え、前記ホイルハウス側締結穴に対して前記ストレーキをボルト締結することによって、前記つば部と前記ホイルハウスとの間に前記ボルト締結面部が挟持されるとともに、前記取付部と前記ホイルハウスとの間に前記インナフェンダが挟持されることを特徴とする。
(実施形態)

ホイルハウスインナ15の車幅外側端部とホイルハウスアウタ16の車幅内側端部とを重ねた重合部が板状部材12bに段付きボルト30で締結固定されている。上記重合部が板状部材12bにボルト締結されることで、より強度を向上させることができる。
リアストレーキ20は、樹脂部品であり、車幅方向視で車両後方側から車体下方に垂下するように逆L字状に折り曲げられたストレーキ本体部20aと、ストレーキ本体部20a前部から車幅方向視で車体上方に立ち上がり、当該折曲げ面がサイドシル12に対してリアインナフェンダ11を介して取り付けるための取付部20bと、ストレーキ本体部20aと取付部20bとの折曲げ位置において上面側に湾曲させて支持剛性を保つ支持部20cと、を有する。
図4、図5に示すように、段付きボルト30は、ナット14に螺着するネジ部30aと、ネジ部30aよりも大径で且つリアストレーキ20のボルト貫通穴20eよりも小径の円筒部30b(頭部)と、ボルト貫通穴20eよりも大径で且つボルト締結面部20dよりも小径のつば部30cと、締結操作のためのボルト部30dと、を軸方向に配列する。
円筒部30bは、軸方向長さL1を有する。軸方向長さL1は、ボルト締結時、樹脂部品であるボルト締結面部20dが適度な締付けとなるように設定される。
この円筒部30bの長さ方向、すなわちつば部30cとホイルハウスアウタ16との間に、リアストレーキ20のボルト締結面部20dが挟持される。
た段差部30eを有する。この段差部30eと、ナット14が固定された板状部材12bの取付面との間に、ホイルハウスインナ15とホイルハウスアウタ16とが挟持される。なお、段差部30eと板状部材12bの取付面までの長さL2は、ホイルハウスインナ15とホイルハウスアウタ16の厚さで決まる。
図2、図4に示すように、リアストレーキ20のボルト締結面部20d側において、ホイルハウスインナ15の端部とホイルハウスアウタ16の端部とを重ね合わせる。そして、この重ね合わせ部分にリアインナフェンダ11の切欠き部11aが臨むようにしてリアインナフェンダ11を配置する。そして、リアインナフェンダ11の切欠き部11aにリアストレーキ20のボルト締結面部20dを挿入し、且つリアインナフェンダ11の切欠き部11bにリアストレーキ20の位置決め締結面部20fを挿入するようにしてリアストレーキ20を配置する。リアストレーキ20のストレーキ本体部20aが、車体下方に垂下した状態となる。
