For this reason, the slope plate 40 in the unfolded state including the first flat plate portion 41 is spanned between the vehicle compartment floor portion (the first hinge 33 connected to the vehicle body) and the road surface. In this way, the inclination angle of the slope plate 40 in the unfolded state can be changed by switching to a state where the second hinge 422 functions or a state where the second hinge 422 does not function. For this reason, boarding of a wheelchair passenger or the like is facilitated by changing the inclination angle according to the weight of the wheelchair passenger, bicycle, luggage, or the like.

  Moreover, since the 2nd flat plate part 42 can be stored below the 1st flat plate part 41 of the slope board 40, a luggage | load can be put now on the 1st flat plate part 41 installed in the vehicle interior. The vehicle body is provided with a support mechanism 35 that holds the first flat plate portion 41 at the storage position of the slope plate 40. Thereby, it becomes easy to load a load on the first flat plate portion 41. Further, the second hinge 422 can be disposed at substantially the same height as the first hinge 33. Further, a luggage storage portion S1 is formed between the first flat plate portion 41 and the floor portion 14 of the vehicle body in a state where the rear end portion of the first flat plate portion 41 is supported by the support mechanism 35. For this reason, the usability of the vehicle 10 provided with the slope board 40 improves. Since the 1st flat plate part 41 of the slope board 40 and the seat back back surface of a sheet | seat can be hold | maintained in the substantially same height position, the usability of a vehicle improves. The first flat plate portion 41 receives a spring force in the upward rotation direction around the first hinge 33, and the spring force is set to a value that can balance the weight of the slope plate. For this reason, the operation | work which expand | deploys the slope plate 40 of a stored state out of a vehicle interior, and the operation | work which stores the slope plate 40 of a expanded state in a vehicle interior become easy.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in this embodiment, although the example which comprises the slope board 40 from the 1st flat plate part 41, the 2nd flat plate part 42, the 3rd flat plate part 43, and the 4th flat plate part 44 was shown, according to the storage position in a vehicle interior Thus, the number of the flat plate portions can be increased or the number can be decreased. In the present embodiment, an example in which the second hinge 422 is switched between a functioning state and a non-functioning state according to the drawing position of the second flat plate portion 42 with respect to the first flat plate portion 41 is shown. However, a configuration in which the second hinge 422 is switched between a state in which it functions by a mechanical lock mechanism and a state in which it does not function is also possible.
