Abstract

L'invention porte sur un véhicule à deux roues automatique, dans lequel véhicule un garde-boue avant est constitué à partir d'un garde-boue supérieur apte à se rapprocher et à s'éloigner d'une roue avant, et d'un garde-boue inférieur disposé au-dessous du garde-boue supérieur de façon à couvrir la roue avant à partir du dessus derrière une fourche avant, et ayant une position relative verticale constante par rapport à la roue avant, le garde-boue supérieur (46) étant formé de façon à s'étendre à l'avant de la fourche avant (11) et derrière celle-ci, avec la partie arrière de celui-ci chevauchant la partie avant du garde-boue inférieur (47) en vue en plan, et est formé de telle sorte que le bord inférieur d'extrémité arrière (46b) du garde-boue supérieur (46) est situé au-dessous de l'extrémité supérieure d'extrémité avant (47c) du garde-boue inférieur (47) tandis qu'un occupant chevauche un véhicule. Par conséquent, la dispersion de boue et d'eau vers le côté occupant peut être réduite par les fonctions mutuelles du garde-boue supérieur et du garde-boue inférieur.
