To provide a resin-made radiator support duct which achieves further reduction in the weight while securing necessary rigidity of a duct component.SOLUTION: A resin-made radiator support duct is configured so that a duct component on one side in a vehicle longitudinal direction and a support component on the other side are joined to each other, has an intake air flow passage flowing air from one end toward the other end in a vehicle width direction therein, has both ends in the vehicle width direction of the support component joined to a vehicle body, and supports a radiator to the lower side of the support component. The duct component includes rigid ribs formed on at least an outer surface on the other end in the vehicle width direction with a reference point positioned at the center in the vehicle width direction as a border in a body range that is the range in the vehicle width range excluding a portion at which all openings for air introduction or discharge positioned on the end in the vehicle width direction in a long portion extending in the vehicle width direction are positioned, and the number of rigid ribs is more than one end side in the vehicle width direction on the other end side in the vehicle width direction with the reference point as the border.SELECTED DRAWING: Figure 1
【課題】樹脂製ラジエータサポートダクトにおいて、ダクト部品の必要な剛性を確保しつつ、さらなる軽量化を図ることである。【解決手段】樹脂製ラジエータサポートダクトは、車両前後方向の一方側のダクト部品と他方側のサポート部品とが結合されて構成され、内部に車幅方向の一端部から他端部に向けて、エアが流れる吸気流路を有し、サポート部品の車幅方向両端部が車体に結合されるとともに、サポート部品の下側にラジエータを支持する。ダクト部品は、車幅方向に伸びた長尺状部分における車幅方向の端部に位置するエア導入用または排出用のすべての開口が位置する部分を除いた車幅方向範囲である本体範囲において、車幅方向中心に位置する基準点を境に、少なくとも車幅方向他端側の外面に形成された剛性リブを含み、本体範囲における剛性リブの数は、基準点を境に、車幅方向他端側で車幅方向一端側より多い。【選択図】図1
