To provide a wheelchair capable of ascending-descending a step in a relatively short time with a stabilized wheelchair posture during ascending-descending actions, without giving uneasiness to an occupant on the wheelchair, and enabling an occupant on the wheelchair to perform step ascending-descending operation alone.SOLUTION: When step descending actions of descending from an upper stage 29 to a lower stage 30 are performed, a wheelchair 1 is used by: rotating a rear arm part 11 so as to direct the tip downward and rotating a front arm part 16 so as to direct the tip downward while rotating in a direction of making the tips of the rear arm part 11 and the front arm part 16 approach each other; lifting front wheels 2 and rear wheels 3 from the upper stage followed by rotating in a direction of separating the tips of the rear arm part 11 and the front arm part 16 from each other; and keeping the inclination of a body 5 constant by coordinating a rear arm drive part 12 and a front arm drive part 17 when grounding the front wheels 2 and the rear wheels 3 on the lower stage.SELECTED DRAWING: Figure 1

    【課題】 昇降動作の間も車椅子の姿勢が安定しており、車椅子の搭乗者に不安感を与えることがなく、比較的短い時間で段差を昇降するができ、車椅子の搭乗者が単身で段差昇降操作を行うことができる車椅子を提供する。【解決手段】車椅子1は、上段29から下段30に下る降段動作を行うときには、後腕部11をその先端が下方に向かうように回転させ、前腕部16をその先端が下方に向かうように回転させるものであり、後腕部11及び前腕部16の先端が互いに接近する方向に回転させ、前輪2及び後輪3を上段から持ち上げ、後腕部11及び前腕部16の先端が互いに離間する方向に回転させ、前輪2及び後輪3を下段に接地させる際に、後腕駆動部12と前腕駆動部17とを協調させることにより本体5の傾きを一定に維持する。。【選択図】図1
