業を行う必要があった。When the load is a highly viscous earth or sand, the bottom plate and the side plate and the bottom plate and the front portion of the driver's seat side are caused by the vibration of the vehicle body and the load earth pressure during the traveling. Earth and sand are strongly adsorbed to orthogonal portions (corners) in three directions with the plate. For this reason, even if it inclines in order to discharge earth and sand etc., earth and sand etc. around the three corners of the bottom plate and the side plate and the bottom plate and the front plate are not discharged. For this reason, it was necessary to perform an operation of sweeping down the adhesive soil and the like around the corners of the bottom plate and the side plates and the bottom plate and the front plate.

て排出される。Since the cargo adhesion preventing plate 10 is provided in this manner, when the vehicle vibrates due to the load or the like when the vehicle is running or stopped, the load earth pressure of the load at the corners is reduced by the load every time the vehicle vibrates. Various rebounds are generated from the arc portion 11 of the adhesion preventing plate 10 to the inside, and the adhesion of the loaded earth and sand is prevented. Therefore, since the adhesion of soil and the like to the three corners of the bottom plate 3 and the side plates 4 and 5 and the bottom plate 3 and the front plate 6 is significantly reduced, if the loading platform 2 is inclined to discharge the load, the load becomes easy. And is discharged.
