To provide a step riding-over device which can be fitted to a handcart, and by which a handcart operator can arbitrarily lift a front wheel.SOLUTION: A step riding-over device comprises: a gear box 26 which can be fixed to a baby carriage 2; a second rack gear 34 which is so provided on the gear box 26 as to be movable in a vertical direction, and can contact a ground surface when moving downward; a lever 51 to which of an upper end of a wire 24 is connected, and which can be fixed to the baby carriage 2; and a conversion mechanism which is provided on the gear box 26, to which a lower end of the wire 24 is connected, and which converts movement such that the wire 24 is pulled upward by operation of the lever 51 into movement such that the second rack gear 34 moves downward. The gear box 26 is lifted with respect to the ground surface by reaction of a force that the second rack gear 34 pushes the ground surface, thereby lifting a front wheel 15 from the ground surface.SELECTED DRAWING: Figure 2

    【課題】手押し車に取り付けが可能であり、手押し車の操作者が任意に前輪を持ち上げることが可能な段差乗り越え装置を提供すること。【解決手段】 ベビーカー2に固定可能なギヤボックス26と、ギヤボックス26に上下方向に移動可能に設けられ、下方に移動した際に地面に接触可能な第2ラックギヤ34と、ワイヤ24の上端が固定され、ベビーカー2に固定可能なレバー51と、ギヤボックス26に設けられ、ワイヤ24の下端が連結され、レバー51の操作によりワイヤ24が上方へ引き上げられる運動を第2ラックギヤ34が下方へ移動する運動に変換する変換機構と、を備え、第2ラックギヤ34が地面を押す力の反作用によってギヤボックス26が地面に対して上昇することにより、前輪15を地面から上昇させる段差乗り越え装置。【選択図】図2
