| Outline of Final Research Achievements |
There is a need for a mechanism that enables a wheelchair user to smoothly get on and off a train without assistance. In this study, we propose a device that enables a wheelchair user to get on and off a railroad car by lifting the wheelchair according to the height of the step by manual operation by the wheelchair user himself/herself. This mechanism was designed and manufactured in accordance with international and domestic standards ISO/JIS. Through experiments with a dummy load and a human subject, we confirmed that the wheelchair is stable with low vibration while getting on and off the train, and that the basic operation is possible by evaluating the time required to operate the lever when stepping over a step. On the other hand, it was also confirmed that a mechanism to support the lever operation is necessary for users who are light in weight and have low arm strength.

| Academic Significance and Societal Importance of the Research Achievements |
モータなどの電気エネルギーを用いた支援装置が多く開発・実用化される一方で，災害時などの電気エネルギーを喪失した場合の利用継続性が懸念される．本研究で開発する「利用者自身の操作力を利活用する機構」の開発は，支援装置の持続的な利用に向けて不可欠である．
また，機構の知能化技術を高めることは，支援機器の低コスト化，送電などのインフラ依存度の低下の実現につながり社会的なバリアフリーの促進に寄与するほか，人の残存機能を活用することで高齢化社会における身体機能の低下の抑止にも寄与するものと考えられる．
