GRILLE SHUTTER ATTACHMENT STRUCTURE OF MOTOR VEHICLE

To secure an opening as large as possible at a structure in which a center stay is provided at a shroud.SOLUTION: In a grille shutter attachment structure of a motor vehicle, a grille shutter unit 3 including multiple shutters 30 extending in a vehicle width direction is attached to a frame-like shroud 2 and a center stay 24 which connects to a center of a shroud upper 21 as seen in a width direction and a center of a shroud lower 22 as seen in the width direction and extends in a vertical direction is integrally formed. Further, a first center frame 63 which extends in the vertical direction and pivotally supports shutter shafts 34o provided at inner ends of the respective shutters 30 as seen in the vehicle width direction is provided at a center part of the grille shutter unit 3 as seen in the vehicle width direction. The first center frame 63 is attached to the center stay 24 so as to be integrated with the center stay 24 and connect the center of the shroud upper 21 as seen in the width direction with the center of the shroud lower 22 as seen in the width direction.SELECTED DRAWING: Figure 2 【課題】シュラウドにセンタステーが設けられた構成においても極力大きな開口部を確保すること。【解決手段】枠状のシュラウド２に、車幅方向に延びる複数のシャッタ３０を備えたグリルシャッタユニット３が取付けられ、シュラウドアッパ２１幅中央とシュラウドロア２２幅中央とに連結する上下方向に延びるセンタステー２４が一体形成されるとともに、グリルシャッタユニット３の車幅方向の中央部に、上下方向に延びて各シャッタ３０の車幅方向の内端に設けられたシャッタ軸３４ｏを軸支する第１センタフレーム６３を有し、該第１センタフレーム６３がセンタステー２４と一体となってシュラウドアッパ２１幅中央とシュラウドロア２２幅中央央と連結するように取付けられた。【選択図】図２
