Abstract

　Selon l'invention, une caisse de véhicule arrière (10) a trois éléments : un premier élément (20), un deuxième élément (30), et un troisième élément (40). Une partie d'extrémité (30b) du deuxième élément (30) est superposée à une partie d'extrémité (20b) du premier élément (20) de telle sorte que les surfaces se chevauchent mutuellement. Une troisième partie de surface (40a) du troisième élément (40) est superposée à une surface arrière (20c) d'une zone d'une première partie de surface (20a) où une deuxième partie de surface (30a) est superposée. La troisième partie de surface (40a) est agencée de façon à s'étendre le long de la direction dans laquelle s'étendent la première partie de surface (20a) et la deuxième partie de surface (30a). Une première partie de guidage (26) inclinée de façon à se séparer à partir du deuxième élément (30) est formée dans une zone de la première partie de surface (20a) qui exclut la zone où est superposée la troisième partie de surface (40a). Une seconde partie de guidage (36) inclinée de façon à se séparer à partir du premier élément (20) est formée dans une zone à l'intérieur de la deuxième partie de surface (30a) où est superposée la troisième partie de surface (40a).
