Claims

[Scope of utility model registration request]

Connecting rods are installed across the rear ends of the left and right footboards, which are stored with the rear ends left and right on the rear left and right sides of the lower surface of the loading platform, and the piston rods of the cylinders on the lower surface of the loading platform are connected to these connecting rods. A shaft-shaped movable body connected to the front end of the footboard is suspended between parallel guide rails along the left and right sides of the footboard so that it can move back and forth, and the rail surface portion of the guide rail below the loading platform is suspended between parallel guide rails. The footboard is horizontally shaped so that the footboard can be guided thereunder, and the rear end of the protruding rail surface passes through the opening of the tail part of the cargo bed from near the tail of the loading platform in the guide rail, and the rear end of the protruding rail surface is connected to the upper surface of the front end of the footboard. An automatic walking device for a freight vehicle, which is formed in an upwardly inclined shape from a rail surface part so as to be able to guide it to a drawer position flush with a loading platform surface at the rear side of a loading platform tail section.
