To prevent a walker from unintentionally moving by acting a prescribed amount or more of downward load on handles when a user seated on a chair, etc. stands up while gripping the handles.SOLUTION: A walker includes: a car body formed with frames extending in vertical direction; a pair of front wheels attached to a lower part of the car body; a pair of rear wheels 13 attached to the lower part of the car body via a pair of rear-wheel cases 18; and a pair of handles attached to the upper part of the car body. The walker further includes a pair of rear-wheel rotation control mechanisms 23 that, when the prescribed amount or more of downward load acts on the pair of handles, push the pair of rear wheels 13 relatively into the pair of rear-wheel cases 18 by the lowering of the pair of rear-wheel cases 18 to prevent rotation of the pair of rear wheels 13 and, when releasing the prescribed amount or more of downward load having acted on the pair of handles, project the pair of rear wheels 13 relatively from the pair of rear-wheel cases 18 by lift of the pair of rear-wheel cases 18 to allow the rotation of the pair of rear wheels 13.SELECTED DRAWING: Figure 1

    【課題】使用者が椅子等に座った状態でハンドルを把持して立ち上がるときに、ハンドルに所定量以上の下向きの荷重が作用して、歩行車が意図せずに移動するのを防止する。【解決手段】歩行車は、フレームにより鉛直方向に延びて形成された車体と、車体の下部に取付けられた一対の前輪と、車体の下部に一対の後輪ケース18を介して取付けられた一対の後輪13と、車体の上部に取付けられた一対のハンドルとを備える。歩行車は、一対のハンドルへの所定量以上の下向きの荷重の作用時に一対の後輪ケース18の下降により一対の後輪13を一対の後輪ケース18に相対的に押込んで一対の後輪13の回転を阻止しかつ一対のハンドルに作用していた所定量以上の下向きの荷重の解除時に一対の後輪ケース18の上昇により一対の後輪13を一対の後輪ケース18から相対的に突出させて一対の後輪13の回転を許容する一対の後輪回転制御機構23を更に備える。【選択図】図1
