Abstract

L'invention a pour objectif la fourniture d'un véhicule pliable dans lequel un châssis avant peut être plus fixé de manière plus fiable à un châssis principal. Le côté court (11B) d'un châssis principal (11) d'un véhicule (10) est relié, à l'aide d'une partie de liaison (12) interposée entre eux, à une partie de guidage (13) montée avec un châssis avant (15). La partie de guidage (13) est pourvue d'une rainure de guidage (13A) qui guide une partie d'adaptation (57) de la partie de liaison (12) dans la direction verticale du véhicule. Une partie d'encoche (41B) pour adapter la partie d'adaptation (57) est formée au niveau de l'extrémité inférieure de la rainure de guidage (13A). Lorsqu'une partie de préhension (63) d'une partie de levier (53) est tournée avec la partie d'adaptation (57) adaptée sur la partie d'encoche (41B), la partie de préhension (63) est serrée contre une partie filetée, fixant ainsi la partie de liaison (12) et la partie de guidage (13).
