Thereby, the loading / unloading of the luggage 5 can be performed more easily.

  Further, when the lateral width of the luggage 5 is smaller than that of the cargo bed 3, it is possible to easily load more luggage 5 by moving the support member 35 in the left-right direction.

  The cargo unloading apparatus 1 can be freely attached to and detached from the loading platform 3 of the vehicle 2. When mounting on the loading platform 3, first, the substrate 70 is placed on the loading platform 3 and fixed with screws or the like. Next, the inner rail 50 is placed on the substrate 70 and fixed with the vertical pins 51. Subsequently, the main rail 10 is fixed to the inner rail 50 with bolts or the like. Subsequently, the lifting and moving device 30 is placed on the main rail 10 and the carriage 60 is placed on the inner rail 50. Then, the extension rail 20 is attached to the main rail 10 and the support legs 21 are attached. All of these members are set to a weight that can be handled by one worker. Therefore, the attachment and detachment of the device 1 can be easily performed by a single operator as in the case of loading and unloading the luggage 5.

  The baggage unloading apparatus according to the present invention can be used not only for light trucks but also for other truck vehicles, railroad vehicles, and ships.
