To provide a stair ascending and descending device which can be used as an electric wheelchair and allows a subject to move by ascending and descending stairs by his/her operation while the subject is seated.SOLUTION: In a travelling state as an electric wheelchair 1, a rear-wheel drive part 33 and a front-wheel drive part 43 are controlled to drive to travel in a direction and at a speed according to operation by a subject. In moving from the travelling state to an ascending and descending state of stairs, a front side rotation drive part 42A, 42B and a front side linear motion drive part 44A, 44B are controlled to move a pair of front wheel parts 40A, 40B backward for keeping a seat part 11 horizontal when a lower end of a second frame 10B is grounded, and simultaneously, an ascending and descending drive part 20 is controlled to move a supporting shaft 21 together with a pair of rear side arm parts 31A, 31B and a pair of rear wheel parts 30A, 30B to an upper end of a third frame 10C.SELECTED DRAWING: Figure 1

    【課題】本発明は、電動車椅子と兼用でき、かつ対象者が着座した状態のまま自らの操作で階段を昇降移動することが可能な階段昇降装置を提案する。【解決手段】電動車椅子1としての走行状態では、後輪駆動部33および前輪駆動部43を制御して、対象者の操作に応じた方向および速度で走行駆動させる一方、走行状態から階段の昇降状態に移行する際、前側回動駆動部42A、42Bおよび前側直動駆動部44A、44Bを制御して、第2フレーム10Bの下端が接地しても座部11を水平に維持するように一対の前輪部40A、40Bを後方移動させると同時に、昇降駆動部20を制御して、支持シャフト21を一対の後側アーム部31A、31Bおよび一対の後輪部30A、30Bとともに第3フレーム10Cの上端まで移動させる。【選択図】図1
