PROBLEM TO BE SOLVED: To simplify a structure, and to facilitate height adjusting work.SOLUTION: Step board parts 2, 3 are connected in a zig-zag manner by a hinge part 5 to be foldable in a traveling direction of a wheel chair in a layered manner. Since a pair of leg parts 9 whose height is adjustable are provided in a horizontal direction on a side of a connecting part of the lowermost step board part 2 in the layered manner as the step board parts 2, 3 are folded, and no leg part is provided at the other end part of the step board part 2, a structure is simplified. After the height of one leg part 9 out of the right and left leg parts is adjusted, the height of the other leg part 9 is adjusted in adjusting the height of the leg part 9. Thus, it is easy to adjust the height. In a structure where a tip end part of the leg part 9 is projected to a side of the step board part 3, a distance between landing points by a slope part and the leg part 9 in the traveling direction 4 of the wheel chair becomes long. Consequently, stability in placing a slope device 1 constituting a slope between an upper floor part and a lower floor part is increased.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】構造の簡単化と高さ調整作業の容易化とを図る。【解決手段】踏板部2,3が積層状になるように車椅子の進行方向に折りに畳み可能にヒンジ部5でジクザク状に連結され、踏板部2,3が折り畳まれて積層状になった最下部の踏板部2の連結部の側には高さ調整可能な脚部9が左右方向で1対設けられ、踏板部2の他端部には脚部が設けられていないので、構造が簡単になる。脚部9の高さを調整する場合、左右のうちの一方の脚部9の高さを調整した後、他方の脚部9の高さを調整することにより、高さ調整がし易い。脚部9の先端部が踏板部3の側に突出した構造になれば、スロープ部と脚部9とによる車椅子の進行方向4の方向における着地点間の距離が長くなり、上記スロープを構成するスロープ装置1の上床部と下床部とに渡された場合の安定性が増加する。【選択図】図1
