Claims3
A motor truck comprising a frame device, a body device movable relative to the frame device, bolt members extending vertically at opposite sides of said frame and body devices to hold said devices together, and an energy transforming means comprising a plate member fixed to one of said devices and formed with an elongated slot inclined forwardly and upwardly and with a bore at a lower end of said slot, the diameter of said bore being greater than the width of said slot, and a cylindrical member fixed to the other of said devices and passing through said bore whereby said body device can be moved upwardly by said energy transforming means when a longitudinal impacting force of or greater than a predetermined value is applied and said slot and cylindrical member are moved relative to each other to cause deformation of said slot and said plate member.
