PROBLEM TO BE SOLVED: To provide a tire deflector device that increases an air drag coefficient (Cd value) by preventing entrance of a travel wind into a wheel house by inhibiting the travel wind from directly hitting a front wheel.SOLUTION: A deflector 20 comprises a first air guiding part 21 that is positioned at an inside in a vehicle width direction, and a second air guiding part 22 that is positioned at an outside in the vehicle width direction. The first air guiding part 21, which has a gentle slope 23 inclined backward and downward, is at a position not overlapping with a front wheel 13 in the vehicle width direction. The second air guiding part 22, which has a guide surface 24 for guiding a travel wind backward and a vertical wall part 25 extended downward from a back part of the guide surface 24 and extended in the vehicle width direction, is at a position overlapping with the front wheel 13 including a vehicle-width-direction innermost side of the front wheel 13 in the vehicle width direction. The guide surface 24 is arranged in such a manner that a ground height is higher than the gentle slope 23, and the first and second air guiding parts 21 and 22 are adjacently arranged.SELECTED DRAWING: Figure 4
【課題】前輪に直撃する走行風を抑制することで、ホイールハウス内に走行風が入り込まないようにし、空気抗力係数(Cd値)の向上を図るタイヤデフレクタ装置を提供する。【解決手段】デフレクタ20は車幅方向内側に位置する第1導風部21と、車幅方向外側に位置する第2導風部22とを備え、第1導風部21は後ろ下がりに傾斜する緩斜面23を有して、車幅方向で前輪13に重複しない位置にあり、第2導風部22は走行風を後方に案内する案内面24と、案内面24の後部から下方に延びると共に、車幅方向に延びる縦壁部25とを有して、車幅方向で前輪13の車幅方向の最も内側を含む前輪13に重複する位置にあり、案内面24は緩斜面23よりも地上高が高くなるよう配置され、第1導風部21と第2導風部22とは隣接して配置されたことを特徴とする。【選択図】図4
