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 convex deflector 20 is arranged on a bottom of a vehicle ahead of a front wheel 13, at a lower position when being viewed from a longitudinal direction of the vehicle. The deflector 20 comprises a first air guiding part 21 that is positioned at an inside in a vehicle width direction, a second air guiding part 22 that is positioned at an outside in the vehicle width direction, and a connection part 26 that connects the first and second air guiding parts 21 and 22 in a vertical direction of the vehicle and that is extended in a longitudinal direction of the vehicle. A vertical wall part 25, which is extended downward from a back part of the second air guiding part 22 and extended in the vehicle width direction, is provided. The second air guiding part 22 is formed in such a manner that a ground height is higher than the first air guiding part 21. A curved part 40 is formed between the first air guiding part 21 and the connection part 26.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の提供を目的とする。【解決手段】車両前後方向から見て下方に凸状のデフレクタ20が前輪13前方の車両底部に配置され、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、第1導風部21と第2導風部22とを車両上下方向につなぐと共に車両前後方向に延びる連結部26とを備え、第2導風部22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を有し、第2導風部22は第1導風部21よりも地上高が高く形成されると共に、第1導風部21と連結部26との間に湾曲部40が形成されたことを特徴とする。【選択図】図4
