By operating a lever provided in the driver's cab, the front, rear, left and right hinges of a cargo box mounted on a small body can be adjusted. The base end of the main lever is fixed to a support member rotatably supported by the mounting frame, and the base end of the main lever is fixed to a support member rotatably supported by the mounting frame. A slide regulating member for preventing the handling of the auxiliary lever is provided on the part, a push-pull wire connected to each hinge part is attached to the outside, and a spring is provided on the auxiliary lever to always bias the auxiliary lever in the contraction direction. The present invention also relates to a lever device for direction control in a three-turn dump truck, which is provided with a rotation regulating member that engages with a stopper on the mounting frame side to restrict rotation of the lever when the auxiliary lever is contracted.
