Further, a duct provided with an external communication hole communicating with the outside air may be provided on the floor of the vehicle body, and a floor mat provided with the large number of dust drop holes may be provided on the duct. According to such a configuration, dust and sand on the floor mat are sucked out to the duct side by a negative pressure from the dust drop hole, the mat is always kept clean, and even if the dust and sand are not discharged out of the vehicle at once, While the vehicle is traveling, it is eventually discharged from the duct to the outside.

The external communication hole may be an opening at the front and rear ends of an external air passage formed in the duct, and a floor mat may be provided so that the dust drop hole faces the external air passage. In this case, it is preferable to continuously connect a negative pressure generation auxiliary plate capable of rectifying the airflow in the outside air passage while reducing the diameter of the hole in the dust drop hole of the floor mat.

With this configuration, during traveling, air flows smoothly in the outside air passage of the duct, and dust and sand on the floor mat are sucked out of the dust drop hole by negative pressure due to the Venturi effect, and the air flows through the outside air passage. And is discharged outside the vehicle.

Further, dust and sand on the floor mat can be dropped into the duct once and then discharged from the duct to the outside of the vehicle by negative pressure. As a form of the floor mat in this case, for example, an endless mat that can be wound around a winding shaft disposed at a fixed interval can be used.

That is, by disposing such an endless mat on a duct provided with an external communication hole communicating with the outside air as described above, the mat surface contaminated with dust and sand is rotated and sent to the duct side. Dust and sand on the mat can be automatically discharged to the outside of the vehicle directly or after being once dropped into a duct, by a negative pressure generated during traveling.

Further, the floor mat can be detachably attached to the duct. That is, only removal of dust and sand is performed by negative pressure during traveling, and when cleaning the entire mat, the mat may be removed from the duct and periodically washed with water. Therefore, the floor mat can always be kept clean.

Incidentally, it is preferable to connect a mudguard body to the external communication hole.

That is, when traveling in rainy weather or when the road surface is wet, or when passing over a puddle or the like, mud splashes can be prevented from entering muddy water from the external communication hole into the vehicle. .
