PROBLEM TO BE SOLVED: To reduce a flow rate of turbulent air ejected from a wheel house to vehicle side faces, as well as to control an increase in air pressure built up ahead of a ground surface portion contacting a tire so as to reduce travel resistance, by guiding an air flow generated in the wheel house by being dragged with a tread surface of the rotating tire into the wheel house.SOLUTION: A tire flap is added to guide air flowing along an inner surface of a wheel cover, to a laterally inner side. Alternatively the wheel cover is formed in a shape incorporating continuous irregularity having a function guiding an air flow to the laterally inner side, or in a shape having a gradient to make a clearance between the wheel house cover and a tire tread surface wider in the laterally inner side than a laterally outer side.SELECTED DRAWING: Figure 1
【課題】回転するタイヤのトレッド面に引きずられることによって生じるホイールハウス内の空気の流れをホイールハウス内側に導くことによって、ホイールハウスから車体側面に噴き出される乱れた空気の流れを減少させるとともに走行中にタイヤ接地面前方に生じる空気の圧力上昇を押さえ走行抵抗を減少させる。【解決手段】ホイールハウスカバー内側に沿った空気の流れを内側に導く整流板を付加する。または、ホイールハウスカバーを空気の流れを内側に導く機能を有する連続した凹凸を組み込んだ形状にするか、ホイールハウスカバーとタイヤトレッド面の隙間を外側より内側が広くなるように勾配を設けた形状にする。【選択図】図1
