To provide a locomotion vehicle that is able to securely pull back a backward separated wheel forward without a complicated operation performed by a user.SOLUTION: A walking-aid vehicle 10 as a locomotion vehicle comprises: a wheel 31; a grounding part that, when the wheel 31 comes into contact with a higher step, is brought into contact with the ground on a higher-step side; a separation mechanism that, when the wheel 31 comes into contact with the higher step, separates the wheel 31 backward with respect to the grounding part as the grounding part moves forward; an urging member by which the wheel 31 separated backward by the separation mechanism is pulled back forward; and upper moving means that moves the wheel 31 upward as the grounding part moves forward.SELECTED DRAWING: Figure 1
【課題】使用者が煩雑な操作を行わなくても、後方へ離間した車輪を確実に前方に引き戻すことができる移動用車を提供する。【解決手段】移動用車としての歩行車10は、車輪31と、車輪31が上り段差に当接した場合に、上り段差を上った側の地面に接地される接地部と、車輪31が上り段差に当接した場合に、接地部の前進に伴い、接地部に対して車輪31を後方へ離間させる離間機構と、離間機構により後方へ離間した車輪31を前方へ引き戻す力を発生させる付勢部材と、接地部の前進に伴い、車輪31を上方へ移動させる上方移動手段と、を備えている。【選択図】図1
