The elastic support member 80 has elasticity, and the elastic support member 80 can be elastically deformed to be separated from the lower surface of the nth door panel by a lateral thrust applied to the elastic support member 80 when the nth door panel is pushed toward the nth door panel, thereby not blocking the nth door panel from being caught on the nth door panel.

For example, when the first door panel 110 is fitted over the second door panel 120, the first door panel 110 may push the elastic support 80 in a lateral direction (a direction from the cargo box toward the cockpit), and the elastic support 80 may be elastically deformed, thereby not blocking the first door panel 110 from being fitted over the second door panel 120. When the second door panel 120 is sleeved on the third door panel 130, and the third door panel 130 is sleeved on the fourth door panel 140, the elastic supporting member 80 arranged at the corresponding position is also elastically deformed, so that the nesting of the door panels when the door is opened from the back to the front is not influenced. As an example, the elastic support 80 may include a spring, a lower portion of which is fixed to the lower door frame 60, and an elastic material (e.g., elastic rubber), which may be disposed between an upper portion of the spring and a lower portion of the corresponding door panel. For example, when the resilient support 80 is pushed laterally, the resilient material may elastically deform and compress the underlying spring, thereby not blocking the nesting of the door panels.
