By the way, it is said that the most ideal inclination angle in a wheelchair is 6 degrees. However, in the above prior art, a single tread portion is attached to a place having a step, and since the length of the tread portion is limited, when the step is large, the inclination angle is necessarily large. It is not preferable. In order to solve this, it is conceivable to arrange a plurality of tread portions continuously to form a gentle slope. However, in the above-mentioned prior art, the lower surface of the tread plate portion is simply supported by the height adjustment leg, and no consideration is given to the support structure between the tread plate portion and the height adjustment leg. There was a problem in terms of safety when arranging continuously.

The height adjustment of the height adjusting leg must be performed in a narrow space between the floor and the tread plate from the lateral direction of the tread plate, that is, on the stomach, so that the work is difficult. Even if only one height adjustment leg is used as in the above-described conventional technology, the labor for the operation is not so large, but if a large number of height adjustment legs are installed for ensuring safety, it becomes extremely laborious.

SUMMARY OF THE INVENTION An object of the present invention is to provide a slope for eliminating a step, which can provide a gentle inclination angle regardless of the level of the step, and is excellent in work life and safety.
