PROBLEM TO BE SOLVED: To provide a variable wheelbase vehicle having such a structure that a vehicle body form is not drastically changed even when a wheelbase is expanded and contracted, and thus rigidity thereof is less varied.SOLUTION: Front wheels 6 are rotatably supported on a frame 2, and a pair of rear wheel suspension systems 16 are provided to respectively rotatably support rear wheels 19. The rear wheel suspension system 16 has a support frame 16a provided to be freely moved and fixed in a longitudinal direction with respect to the frame 2. A swing arm 16b is supported on the support frame 16a in a swingable manner, wherein the swing arm 16b rotatably supports the rear wheel 19. A shock absorber 16d is provided between the support frame 16a and the swing arm 16b, and the pair of the rear wheel suspension systems 16 are selectively fixed at a plurality of prescribed positions in the longitudinal direction with respect to the frame 2 to realize different wheelbase conditions. |
