To provide a handcart which can easily ride over a step.SOLUTION: A walker 100 comprises a walker body 200 having a pair of left and right front wheels 220 and rear wheels 230, and a front wheel lifting mechanism 300 for electrically lifting a front wheel 220 of the walker body 200. The front wheel lifting mechanism 300 comprises a single attachment member, a ground contact body, an electric lifting part and an electrical box, and supports the ground contact body, and linearly moves the ground contact body in a vertical direction between a separation position, at which the ground contact body is separated from a ground surface, and a grounding position at which the ground contact body grounds so as to push up the front wheel 220 by a reaction force which the ground contact body receives from the ground surface.SELECTED DRAWING: Figure 1
【課題】段差を容易に乗り越えることができる手押し車を提供する。【解決手段】歩行車100は、左右一対の前輪220および後輪230を有する歩行車本体200と、歩行車本体200の前輪220を電動で持ち上げるための前輪持ち上げ機構300とを備える。前輪持ち上げ機構300は、単一のアタッチメント部材、接地体、電動昇降部および電装箱を備え、接地体を支持するとともに、接地体を、地面から離間している離間位置と、地面から受ける反力により前輪220を押し上げるように接地している接地位置との間で上下方向に直線的に移動させる。【選択図】図1
