PROBLEM TO BE SOLVED: To provide a carrier vehicle replaceable with a dump truck. SOLUTION: This carrier vehicle moves a moving wall 29 to a rear part while moving a conveyor 28 in Fig. (a). Since lightweight chips 66 moves to the right side in the figure at the same speed as the conveyor 28 and the moving wall 29, a further load does not apply to the moving wall 29. Namely, the carrier vehicle does not forcibly push out the lightweight chips 66 by the moving wall 29 but merely prevents the lightweight chips 66 under loading by the moving wall 29 from spilling to the front wall side. Accordingly, merely a load generated by carried loads acts on the moving wall 29. Also, Fig. (b) shows that, since the moving wall 29 reaches the rear part, most of the lightweight chips 66 could be discharged. In addition, in Fig. (c), since unloading operation is completed, a rear door 27 is closed and the conveyor 28 and a chain 43 are reversely moved to return the moving wall 29 to the vicinity of a front wall 24.
