[Prior Art]

 For example, a van-type vehicle that has a wall that is substantially vertical to the back surface, such as a truck with a large van mounted on the loading platform (hereinafter referred to as a van-type truck) or a bus, may have muddy water splashed by itself when traveling on a wet road surface. It was attached and soiled the back. Such dirt on the back creates troublesome problems such as 1) impairing aesthetics, 2) obstructing rearward visibility, and 3) time-consuming car washing. , It has become an important issue in improving the commercial strength of van type vehicles.

Therefore, a conventional countermeasure against mud adhesion to the back surface of the van will be briefly illustrated and described. For example, a cavity 2 may be provided around the back surface of the van 1 (see FIG. 7A) or the van 1 There is a case where a continuous sagging rubber 3 is attached to the lower back side (see FIG. 7B). However, although such conventional measures have some effects, they are not always sufficient, and there are defects as shown in the running test results of FIG. That is, with the measures provided with the cavity 2, the mud adhered to the peripheral portion of the rear surface of the van 1 is reduced as compared with the original shape shown in FIG. 6 (see FIG. 8A) without the countermeasure, but the central portion of the rear surface is reduced. Is not effective until then (see FIG. 8 (b)). Moreover, although the mud adhering to the upper part of the rear surface of the van 1 was reduced by the measure in which the sagging rubber 3 was attached, the effect was not exerted on the entire other parts (see FIG. 8 (c)). Note that FIG. 8 is a front view showing the back surface of the van 1, and each hatched portion is a mud-attached portion.

Against this background, as shown in FIG. 9, a straightening vane 5 is attached behind the rear wheel 4 so as to form a front-increasing inclined surface that descends from the front of the vehicle toward the rear. The effectiveness has become known. This straightening vane 5 knocks off the splashed muddy water to reduce the absolute amount, and is fixed to the frame 6 via the stay 7, and is set so that the inclination angle with respect to the horizontal plane is θ which is an upward rise. Has been done. In FIG. 9, numeral 8 indicates a rear bumper of a van type truck.
