PROBLEM TO BE SOLVED: To provide a step ascent/descent vehicle that is simply configured and that can smoothly travel on a flat road.SOLUTION: A step ascent/descent vehicle 10 includes a main wheel 30 that is rotatively driven, and a wheel 40 for a step, which is rotatively driven around a rotating shaft parallel to a rotating shaft of the main wheel 30 by a driving source 21. The wheel 40 for the step has a plurality of protrusions 41 on an outer peripheral surface. A virtual circle A formed by connecting tips of the plurality of protrusions 41 is larger than a circle drawn by an outer peripheral surface of the main wheel 30, and the lowest point of the virtual circle A is positioned as high as or higher than the lowest point of the outer peripheral surface of the main wheel 30.

    【課題】構成が簡易で、平坦路で円滑に走行することが可能な段差昇降車両を提供する。【解決手段】段差昇降車両10は、回転駆動される主車輪30と、駆動源21によって、主車輪30の回転軸と平行な回転軸回りに回転駆動される段差用車輪40とを備える。段差用車輪40は、外周面に複数の突起41を有し、複数の突起41の先端を結ぶ仮想円Aが、主車輪30の外周面が描く円よりも大きく、且つ仮想円Aの最下点が主車輪30の外周面の最下点に対して同じか又はそれより高い位置にある。【選択図】図2
