Abstract

L'invention concerne un véhicule à enfourcher présentant une configuration offrant réduction de poids et durabilité, et dans laquelle un élément de résine renforcé par des fibres peut être utilisé. Un véhicule (1) selon l'invention est pourvu d'un couvercle latéral (22) qui comprend des couches de fibres de carbone (22a, 22d) contenant une résine et des fibres de carbone qui renforcent une telle résine, et au moins une partie du couvercle latéral forme la surface extérieure de direction gauche-droite du véhicule (1). Entre la couche la plus à l'extérieur des couches de fibres de carbone (22a, 22d) et la surface extérieure du véhicule (1), dans la direction intérieure-extérieure du véhicule (1), le couvercle latéral (22) est formé d'un seul tenant avec la résine. En outre, le couvercle latéral comprend des couches de résine externes (22b, 22e) qui sont portées vers le bas lorsque la surface externe est raclée. Les couches de résine externes (22b, 22e) comprennent, dans une vue depuis la direction gauche-droite du véhicule (1), des parties relativement grandes et des parties relativement petites en termes de l'épaisseur du véhicule (1) dans sa direction gauche-droite.
