(b) Prior art A conventional vehicle transport vehicle has a dump frame on the vehicle body that is tiltable, a loading platform on the dump frame that can be moved back and forth, and the dump frame is tilted at a predetermined angle (approximately 15 degrees). A vehicle, for example, a construction vehicle such as a box hoe, is loaded and unloaded with the loading platform moved rearward.

(c) Problems to be solved by the invention However, in the above-mentioned transport vehicle, the main girder of the loading platform is in direct sliding contact with the dump frame, which increases sliding resistance and makes it difficult to move the loading platform back and forth smoothly. Furthermore, gaps are provided between the sides of the dump frame and the main girder to reduce sliding resistance so that they do not come into contact with each other, but this causes lateral shaking when the loading platform moves back and forth, especially when the loading platform moves backwards. The length of the support portion of the main girder by the dump frame becomes shorter, and the lateral sway increases, creating the risk that the vehicle on the loading platform may slide off the loading platform due to its own weight.
