Description

(a)本発明の燃料タンクは、前記底壁部には、前記路面と略平行に対向する平坦面が形成されており、前記巻き込み抑制突部の下面が、前記平坦面の後方に連なるように配され、且つ後方に向かって前記路面との対向間隔を狭まるように傾斜した形態であってもよい。
この構成によれば、底壁部の下面に沿って流れる空気は、巻き込み抑制突部の傾斜した下面によって斜め下方へ誘導されるので、収容空間への巻き込みが抑制される。また、巻き込み抑制突部の下面の傾斜により、巻き込み抑制突部の後端部では空気の流速が高まるので、ダウンフォースが発生し、走行性能が向上する。
(A) In the fuel tank according to the present invention, a flat surface facing the road surface is formed on the bottom wall portion so as to be substantially parallel to the bottom surface, and a lower surface of the entrainment suppression protrusion is connected to the rear of the flat surface. It may be arranged in such a manner that it is inclined so as to narrow the facing distance from the road surface toward the rear.
According to this configuration, the air flowing along the lower surface of the bottom wall portion is guided obliquely downward by the inclined lower surface of the entrainment suppressing protrusion , so that entrainment into the accommodation space is suppressed. Further, the inclination of the lower surface of the entrainment suppressing projection, the rear end portion of the winding inhibiting projections since the flow velocity of air is increased, downforce is generated, the running performance is improved.

また、燃料タンクAの底壁部13には、路面Gと略平行に対向する平坦面14が形成されている。そして、巻き込み抑制突部16の下面(整流面17)が、平坦面14の後方に連なるように配され、且つ後方に向かって路面Gとの対向間隔を狭まるように傾斜した形態である。この構成によれば、底壁部13の下面に沿って流れる空気は、巻き込み抑制突部16の傾斜した下面によって斜め下方へ誘導されるので、収容区間Hへの巻き込みが抑制される。また、巻き込み抑制突部16の下面の傾斜により、巻き込み抑制突部16の後端部では空気の流速が高まるので、ダウンフォースが発生し、走行性能が向上する。 A flat surface 14 is formed on the bottom wall 13 of the fuel tank A so as to face the road surface G substantially in parallel. And the lower surface (rectification | straightening surface 17) of the entrainment suppression protrusion 16 is distribute | arranged so that it may continue behind the flat surface 14, and it is the form inclined so that the opposing space | interval with the road surface G might narrow toward back. According to this configuration, the air flowing along the lower surface of the bottom wall portion 13 is guided obliquely downward by the inclined lower surface of the entrainment suppression protrusion 16 , so that entrainment into the accommodation section H is suppressed. Further, the inclination of the lower surface of the entrainment suppressing protrusions 16, entrainment since the flow velocity of air is increased in the rear end portion of the suppressing projection 16, downforce is generated, the running performance is improved.
