PROBLEM TO BE SOLVED: To facilitate descending using a body weight of a user without the need of a power source, and not to increase burden even when obtaining a large assisting force in ascending.SOLUTION: An ascending/descending assisting device for stairs includes a slider part 36 along a stair body 3, an ascending/descending guidance part 30 for guiding ascending/descending of a balance weight 39, and an ascending/descending assisting device body 11 joined to the slider part 36. The body 11 includes a running board 13, a support post 12 as a grip part, and a grip part 14 for left hand, including a lever 22 for restraining/releasing upwardly moving. A wire rope 44 connected to the slider part 36 is connected to the balance weight 39 via a sheave 40 above the ascending/descending guidance part 30, and a coil spring 47 is interposed between the upper ends of the balance weight 39 and the ascending/descending guidance part 30. The balance weight 39 and the coil spring 47 are so formed that when the body 11 is upward movable, and an external force is not applied by a user, the body 11 moves upward, and when the user rides on in a state that the body 11 is near the uppermost stage, descending is started, and a descending speed is reduced close to zero near the bottom.SELECTED DRAWING: Figure 1

    【課題】 動力源不要で、利用者の体重を利用して楽に下降でき、上昇時に大きな補助力を得られるようにしても負担が増大しない。【解決手段】 階段本体3沿いにスライダ部36、釣り合い錘39を昇降案内する昇降案内部30を備え、スライダ部36に昇降補助装置本体11を結合する。本体11は踏み板13、掴み部としての支柱12、上昇移動の拘束・解除をするレバー22を備えた左手用掴み部14を含む。スライダ部36に連結したワイヤロープ44を昇降案内部30の上方のシーブ40を介して釣り合い錘39に連結し、釣り合い錘39と昇降案内部30の上端の間にコイルバネ47を介装する。釣り合い錘39とコイルバネ47は、本体11が上昇移動可能で、かつ利用者が外力を掛けていないとき本体11が上昇し、本体11が最上段近くにある状態で利用者が乗ったときは下降を開始し、最下段近くで下降速度を零近くに減速する構成とする。【選択図】 図1
