PROBLEM TO BE SOLVED: To provide a foldable wheelchair which has high straight advancing property and durability even when being given load and shock and is highly safe.SOLUTION: Casters 7, 7 and main wheels 8, 8 are mounted in both end parts of a chassis 3 in which lateral frame members 32, 32 are bridged between a pair of longitudinal frame members 31, 31 placed in parallel at a distance in the width direction of a wheelchair. To surrounding surfaces of ceiling parts at one-side end parts of the longitudinal frame members 31, 31, lower ends of leg part frame members 52, 52 are joined in such a way that they can turn around shafts parallel to the lateral frame members 32 to be the width direction of the chassis 3. The leg part frame members 52, 52 are divided into first leg part frame members 521, 521 and second leg part frame members 522, 522 in the longitudinal-direction middle positions of the leg part frame members, and the first leg part frame members 521, 521 and the second leg part frame members 522, 522 are joined to each other by bending means 9, 9 which can be bent in the prescribed direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】 荷重及び衝撃が与えられても直進性及び耐久性が高く、また安全性も高い、折り畳み可能な車椅子を提供する。【解決手段】 車椅子の幅方向に距離を隔てて平行に配置した一対の縦フレーム部材31,31の間に横フレーム部材32,32を架設してなるシャシ3の両端部にキャスタ7,7及び主輪8,8が取り付けてある。縦フレーム部材31,31の一端部の天井部周面には脚部フレーム部材52,52の下端が、シャシ3の幅方向である前記横フレーム部材32と平行をなす軸周りに回動可能に連結してある。脚部フレーム部材52,52はその長手方向の中途位置で、第1脚部フレーム部材521,521と第2脚部フレーム部材522,522に分割されており、第1脚部フレーム部材521,521と第2脚部フレーム部材522,522とは所定方向へ屈折可能な屈折手段9,9によって相互に連結されている。【選択図】 図1
