PROBLEM TO BE SOLVED: To provide a vehicular undercover that can make both improvement in heat-exhaust performance and improvement in aerodynamic performance compatible.SOLUTION: A first cover 1A has a louver 12 comprising a plurality of fixed louver boards 11. When a front direction of a vehicle is designated as a front Dand a rear direction of the vehicle is designated as a rear Dand when the louver 12 is viewed from a side, the louver boards 11 are inclined at angles of 25 degrees or more and 70 degrees or less so that front ends 111 thereof face upward more than rear ends 112 thereof. A second cover 1B has a louver 12 comprising a plurality of fixed louver boards 11. When the front direction of the vehicle is designated as the front Dand the rear direction of the vehicle is designated as the rear D, and when the louver 12 is viewed from a side, the louver boards 11 are inclined at angles of 25 degrees or more and 70 degrees or less so that the front ends 111 thereof face downward more than the rear ends 112 thereof, and a space between the louver boards 11 adjacent longitudinally is not opened in a normal direction Dof a virtual line L joining the rear ends 112 of the louver boards.SELECTED DRAWING: Figure 1
【課題】排熱性能の向上と空力性能の向上とを両立できる車両用アンダーカバーを提供する。【解決手段】第1のカバー1Aは、固定された複数の羽板11を備えるルーバー12を有し、車両の前方向を前方DF、車両の後方向を後方DRとし、ルーバー12を側方視した場合に、羽板11は、前端111が後端112よりも上を向くように、角度25度以上70度以下に傾斜される。第2のカバー1Bは、固定された複数の羽板11を備えるルーバー12を有し、車両の前方向を前方DF、車両の後方向を後方DRとし、ルーバー12を側方視した場合に、羽板11は、前端111が後端112よりも下を向くように、角度25度以上70度以下に傾斜され、前後に隣り合った羽板11間が、これらの羽板の後端112を結んだ仮想線Lの法線方向DLVに開口されない。【選択図】図1
