PROBLEM TO BE SOLVED: To obtain a truck with a lifting/lowering platform capable of conveying a storage box easily not depending on a type of a locking stepped part formed in the lower part of the storage box. SOLUTION: In this truck, the lifting/lowering platform (20) covering the inside and the upper face of a fork-shaped frame (16) is configured to be vertically movable relative to the frame (16), and window holes (20c) are formed in the opposed inner side walls of the platform (20) at prescribed intervals in the longitudinal direction. Furthermore, L-shaped locking tools (21) with horizontal claws are provided in the lower end of arms (21a), and the claws (21b) of the locking tools (21) are fitted to the respective window holes (20c) outwardly and rotatably connected to the platform (20). Moreover, between each of the locking tools (21) and the opposed frame (16), a cam device (25) allowing the rotation of each locking tool (21) in a direction exposing the claw (21b) from the window hole (20c) at the initial lifting time of the platform (20), and the rotation thereof in a direction retracting the claw (21b) inside the window hole (20c) at the lowering time of the platform is provided.
