PROBLEM TO BE SOLVED: To provide a wheelchair for which a structure is simplified by making a seating face adjustable to a desirable posture in a simple operation when the wheelchair is moved on a slope.SOLUTION: The wheelchair is composed of an upper frame 1 that forms a framework of a wheelchair body, and a pair of right and left lower frames 2 that support wheels. Each of the lower frames includes: a base frame 20 that is arranged along a surface in contact with the wheels； post frames 21 that are erected at least in three places on an upper face of the base frame； a connection frame 22 that connects the respective post frames with each other； and a columnar movable member 3 that is vertically movable along each of the post frames. The respective post frames are arrayed with prescribed spaces apart along the traveling direction of the wheels. When the movable members, which are vertically movable along the post frames situated in the center of respective post frame arrays, are in a height position incapable of moving downward, the respective movable members are set in a downward movable amount so that the movable members in the front and in the rear become rockable with these movable members as an axis, and are held hanging on the upper frame.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】傾斜面の移動時に座面を簡単な操作で望ましい姿勢に調整でき、構成を簡易にした車椅子を提供する。【解決手段】椅子本体の骨格を形成する上部フレーム１と、車輪を支持する左右一対の下部フレーム２とを備え、各下部フレームは、車輪が接する面に沿って配置される基部フレーム２０と、基部フレームの上面の少なくとも３箇所に立設される支柱フレーム２１と、各支柱フレームを相互に連結する連結フレーム２２と、各支柱フレームのそれぞれに沿って上下動が可能な柱状の可動部材３とを有し、各支柱フレームは、所定の間隔で車輪の進行方向に沿って並んで配列されており、各可動部材は、各支柱フレームの列の中央に位置する支柱フレームに沿って上下動が可能な可動部材が下方への移動ができない高さ位置にあるときに当該可動部材を軸としてその前後の可動部材が揺動可能となるように下方への移動可能量が設定されて上部フレームに吊り支持される、車椅子。【選択図】図１
