PROBLEM TO BE SOLVED: To permit loading into a truck with a high gate by forming a rectangular pipe in a first actuating lever into a state of bending in approximately arcuate shape from the side view. SOLUTION: A bucket 1 is composed of a bucket body 2 and a support frame 3. The rear ends of first actuating levers 4 constituted to be extensible are connected into the upper end positions of lateral vertical frames 3C, 3D, and the tips of the first actuating levers 4 are connected to the lower side tips of lateral side plates 2C, 2D. Rectangular pipes 4A of the first actuating levers 4 are bent in approximately arcuate shape from the side view to enlarge an angle to a bottom plate 2B. The tips of first hydraulic cylinders 8 are connected to the lower faces of the first actuating levers 4. The nearly center parts of first links 10 are connected into the nearly middle positions of the first actuating levers 4, and the upper ends are connected to the rear ends of second hydraulic cylinders 11. The length of the extensible levers can thereby be extensible, and since the bucket body 2 ascends at a constant angle, boxed vegetables and the like can be loaded and stored in a high position, and it proves effective in the case of uniformly loading material of undefined shape such as earth.
