A vehicle door (12) can move to a totally closed state, a halfway opened state, and a totally opened state. In the halfway opened and totally opened states, a pivoting connection section (17) between an upper door (15) and a lower door (16) protrudes outward from a vehicle body (11). A support device for the vehicle door (12) has a rod mechanism (19, 30) for connecting the lower door (16) to the vehicle body (11). The rod mechanism (19, 30) has a first support point (20, 31a) provided to the vehicle body (11) and a second support point (21, 32b) provided to the lower door (16). The distance between the first support point (20, 31a) and the second support point (21, 32b) can be reduced or increased. The distance between the support points decreases when the vehicle door moves from the halfway opened state to the totally opened state. The rod mechanism (19, 30) generates urging force for separating the second support point (21, 32b) away from the first support point (20, 31a). Selon l'invention, une porte de véhicule (12) peut se déplacer entre un état de fermeture totale, un état de semi-ouverture et un état d'ouverture totale. Dans l'état de semi-ouverture et d'ouverture totale, une section de jonction par articulation (17) située entre une porte supérieure (15) et une porte inférieure (16) est saillante vers l'extérieur à partir d'une carrosserie de véhicule (11). Un support de porte de véhicule (12) comprend un mécanisme à tige (19, 30) qui raccorde la porte inférieure (16) à la carrosserie (11). Le mécanisme à tige (19, 30) présente un premier point d'appui (20, 31a) ménagé sur la carrosserie (11) et un second point d'appui (21, 32b) ménagé sur la porte inférieure (16). La distance entre ces points d'appui diminue lorsque la porte de véhicule se déplace de l'état de semi-ouverture à l'état d'ouverture totale. Le mécanisme à tige (19, 30) génère une force de sollicitation pour séparer et éloigner le second point d'appui (21, 32b) du premier point d'appui (20, 31a).
