To provide a cooling duct which enables travel wind to be introduced into a heat exchanger efficiently while achieving reduction of manufacturing costs.SOLUTION: Square cylindrical discharge ports 21, 22 of a front upper duct 20 are fitted in upper openings 45, 46 of a rear duct 40 to cause ring shaped protruding pieces 45a, 46a to deflect and contact with outer peripheral surfaces of the square cylindrical discharge ports 21, 22. A rear part of a front lower duct 30 is fitted in a square cylinder part 47 of the rear duct 40 to cause a ring shaped protruding piece 47a to deflect and contact with an outer peripheral surface of the rear part. The rear duct 40 is attached to side brackets 7, 8 to cause free ends of an upper plate part 42 and a lower plate part 43 to be disposed near an upper part and a lower part of a front surface of a radiator 3 and cause protruding pieces 42a, 43a to deflect and contact with the upper part and the lower part of the front surface. Then, a left side and a right side of the front plate part 41 and a left side and a right side of the upper plate part 42 are respectively placed in tight contact with front sides of the side brackets 7, 8 and upper sides of the side brackets 7, 8. Further, a left side and a right side of the lower plate part 43 are placed in tight contact with lower sides of the side brackets 7, 8.SELECTED DRAWING: Figure 1

    【課題】製造コストの低減を図りながら、熱交換器に走行風を効率良く導入可能な冷却ダクトの提供。【解決手段】フロントアッパーダクト20の角筒状排出口21,22をリアダクト40の上開口45,46に嵌入すると、輪状突片45a,46aが撓んで角筒状排出口21,22の外周面に当接される。フロントロアダクト30の後部をリアダクト40の角筒部47に嵌入すると、輪状突片47aが撓んで前記後部の外周面に当接される。サイドブラケット7,8にリアダクト40を取り付けると、上板部42と下板部43の自由端がラジエータ3の前面の上部と下部に接近配置されて突片42a,43aが撓んで前記前面の上部と下部に当接され、サイドブラケット7,8の各前辺に前板部41の左辺と右辺が、また、サイドブラケット7,8の各上辺に上板部42の左辺と右辺が、さらに、サイドブラケット7,8の各下辺に下板部43の左辺と右辺が、それぞれ隙間なく当接される。【選択図】図1
