PROBLEM TO BE SOLVED: To provide a handcart including a novel wheel structure facilitating riding over of a step.SOLUTION: A handcart includes: a vehicle body 10 including a front wheel 11 and a rear wheel 12 a base 13 attached on an undersurface of the vehicle body 10 so as to slide in a front/rear direction and a vertical direction an auxiliary wheel 19 supported on the base 13 an energizing force exertion device 21 exerting energizing force at all times to the base 13 in a forward direction and a guide device 18 which exerts vertical deformation to the base 13 in accordance with front/rear directional deformation of the base 13, maintains an undersurface of the auxiliary wheel 19 at a height equal to or higher than an undersurface of the front wheel 11 when the base 13 advances by the energizing force to a forward movement limit, and lowers the undersurface of the auxiliary wheel 19 to a height lower than the undersurface of the front wheel 11 when the base 13 retreats against the energizing force.COPYRIGHT: (C)2016,JPO&INPIT【課題】段差乗り越えを容易にする新規な車輪構造を備えた手押し車を提供する。【解決手段】手押し車は、前輪11及び後輪12を備えた車体10と、車体10の下面に前後方向及び上下方向にスライド可能に取り付けられたベース13と、ベース13に支持された補助輪19と、ベース13に常時前方への附勢力を与える附勢力付与装置21と、ベース13の前後方向変位に応じてベース13に上下方向変位を与えるものであって、ベース13が附勢力により前方移動限界まで前進したときには補助輪19の下面を前輪11の下面以上の高さに維持し、ベース13が附勢力に抗して後退したときには補助輪19の下面を前輪11の下面未満の高さに降下させる案内装置18と、を備える。【選択図】図1
