PROBLEM TO BE SOLVED: To provide a wheelchair capable of taking a folding form with excellent stability.SOLUTION: A wheelchair 100 includes a self-standing mechanism 130 for making the wheelchair self-stand when folding. The self-standing mechanism includes a supporting leg 131 rotatively connected to a rear leg frame 112 at a connection part 112c below a second connection member 118, and a traction link 132 rotatively connected to the center of the supporting leg and connected to the second connection member. In the wheelchair, a supporting leg tip floats in a travel form from the ground surface, a front wheel 101 and a rear wheel 102 ground, and the supporting leg tip and the rear wheel ground in a folding form so as to let the front wheel float.SELECTED DRAWING: Figure 12COPYRIGHT: (C)2016,JPO&INPIT【課題】安定性に優れた折り畳み形態をとり得る車椅子を提供する。【解決手段】車椅子100は、折り畳み時に該車椅子を自立させる自立機構130を備える。該自立機構は、第2連結部材118の下方の連結部112cで後脚フレーム112に回動式に連結された支持脚131と、支持脚の央部に回動式に連結されるとともに第2連結部材に連結された牽引リンク132とを備える。該車椅子では、走行形態で支持脚先端が地面から浮上するとともに前車輪101及び後車輪102が接地し、折り畳み形態で支持脚先端及び後車輪が接地して前車輪が浮上する。【選択図】図12
