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: In a tire deflector device, a deflector 20 is arranged on a vehicle bottom ahead of a front wheel. The deflector 20 comprises a substantially horizontal part 24 that is substantially and horizontally arranged in a longitudinal direction of a vehicle, and a vertical wall part 25 that is extended downward in a back part of the substantially horizontal part 24 and extended in a vehicle width direction. The deflector is formed in such a shape that an angle made between a lower part of the vertical wall part 25 including at least a lower end of the vertical wall part 25 and a virtual orthogonal surface orthogonal to the substantially horizontal part 24 is in a range of 20-45 degrees.SELECTED DRAWING: Figure 9
【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が前輪前方の車両底部に配置されたタイヤデフレクタ装置であって、上記デフレクタ20は、車両前後方向で略水平に配置された略水平部24と、該略水平部24の後部において下方に延びると共に車幅方向に延びる縦壁部25とを備え、上記縦壁部25の少なくとも下端部を含む縦壁部25下部と上記略水平部24に直交する仮想の直交面とが成す角度が20度〜45度の範囲で形成されたことを特徴とする。【選択図】図9
