[0002]
[Prior art]
As a device for getting on and off a vehicle with a wheelchair, for example, a fully automatic lift type and a slope type are known. In particular, in the case of the slope type, for example, two or three slope plates are foldably coupled via a hinge or the like. When getting in and out of a wheelchair (during use), the slope plate is unfolded in a straight line and is bridged between the vehicle floor (wheelchair loading section) and the boarding place.
[0003]
Further, in the slope type apparatus, for example, as shown in FIG. 7, the slope 100 is folded by folding a plurality of slope plates when the wheelchair W is put in and in the housed state. At this time, the slope 100 is leaned so as to stand substantially upright on the rear part of the wheelchair W loaded on the floor 2 at the rear part of the body 1 as shown in the figure.
