  • the inclined support portion 47b of the sub frame 47 is configured to be supported in parallel.
  • the loading platform 45 can be smoothly moved to the horizontal support portion 47a or the inclined support portion 47b of the subframe 47 via the flat belt body 110.
  • the rear end portion of the inclined support portion 47b rotates downward around the bending support shaft 126 against the spring force of the spring mechanism 127. Since the loading platform 45 is inclined backward, it is possible to easily reduce the collapse of the cargo when the luggage 105 is unloaded from the loading platform 45.
  • the loading platform 45 moves from the inclined support portion 47b to the horizontal support portion 47a, the rear end portion of the inclined support portion 47b rotates upward around the bending support shaft 126 by the spring force of the spring mechanism 127, Since the loading platform 45 is shifted from the backward inclined posture to the horizontal posture, the loading platform 45 can be smoothly moved from the inclined support portion 47b to the horizontal support portion 47a, and the loose load 105 can be easily prevented from falling off the loading platform 45.
