Abstract
PURPOSE:To eliminate the possibility of a flap's falling down due to the coming- off of a hook even when an outerward force is applied to a pin in the lower part of the flap board by constituting the device so that an engaging piece provided for the flap be engaged with the engaging member of the cargo platform when the flap board is rotated downward for unloading. CONSTITUTION:Upper pins 6... provided in the upper part on both sides of a flap 5 are fastened, in a removal-free manner, by upper metals 7... fitted on the side of a cargo platform 4 of a rear body 1. Moreover, a lower pin 9 fitted to the lower part of the flap 5 through a supporting piece 8 is fastened by a pin-holding metal 10 and a hook 12 fitted on the side of the platform 4. In addition, an engaging piece 9 is provided in the lower part of the flap board 5, while an engaging member 20 being provided on the side of the platform 4 located inside the rear body deeper than the engaging piece 19 and opposing to the piece 19. By this, when the flap board 5 is rotated downward, the engaging piece 19 is engaged with the engaging member 20, thus preventing the lower pin 19 from getting out of the outerside of the rear body, even when the hook comes off by the force of the pin 9 to move outside the rear body.
