PROBLEM TO BE SOLVED: To provide a transport vehicle that can take a folded form having excellent safety.SOLUTION: A transport vehicle 100 is equipped with a pair of front casters 101, a pair of rear casters 102, and a pair of wheels 103 which are so provided as to be mounted between the front caster 101 and the rear caster 102. The transport vehicle 100 is further equipped with: longitudinal frames 111, 112 which respectively support the front caster 101 and the rear caster 102 a support frame 113 which extends in a substantially vertical direction between the longitudinal frames 111, 112 and supports the wheel 103 and base frames 114, 115 which are rotatably constructed between each of the longitudinal frame 111, 112 and the support frame 113. The support frame 113 is equipped with an interpolation component 113a on which the wheel 103 is mounted, and an extrapolation component 113b to which base frames 114, 115 are rotatably connected and which is so extrapolated as to be slidable with respect to the interpolation component 113a.SELECTED DRAWING: Figure 2
