PROBLEM TO BE SOLVED: To provide a front part structure of a box-shaped vehicle which can fully reduce a travel resistance.SOLUTION: In a box-shaped vehicle 10 having a front face 12, which vertically extends, below a front window 11, a swollen body 20, which swells forwards from the front face 12 so as to gradually narrow towards a tip thereof and reduces an air resistance, is provided on the front face 12 so as to be capable of expanding and contracting. The swollen body 20 is configured from a bag body which expands by filling compressed-air into the interior thereof. When a travel speed of the box-shaped vehicle is equal to or higher than a predetermined value, the compressed-air is introduced into the swollen body 20 thereby expanding the swollen body 20, and when the travel speed of the box-shaped vehicle is lower than the predetermined value, air is discharged from the swollen body 20 thereby contracting the swollen body 20.

    【課題】走行抵抗を十分に軽減することができる箱形車両の前部構造を提供する。【解決手段】フロントウインドウ11の下方に、略鉛直方向に延びる前面12を有する箱形車両10において、前面12に、前面12から前方に向かって先狭に膨出して空気抵抗を低減する膨出体20を、膨縮可能に設けた。膨出体20は、内部に圧縮空気が充填されることで膨張する袋体で構成され、箱形車両の走行速度が所定値以上のとき、膨出体20に圧縮空気が導入されて膨出し、箱形車両の走行速度が所定値未満のとき、膨出体20から空気が排出されて収縮する。【選択図】図2
