Abstract: This invention relates to an improved van body which is used with a container car, a freight car, and a truck and comprises inverse L-shaped side frames located at the right and left side walls of the front and the back of the floor, said side frames being so constructed that the top right and left ends thereof can contact each other at the top center when closed and separate when opened. Shields, each bridging the inverse L-shaped side frames on the same side, provide the vane opening and closing operations at both top ends.
