Abstract: PURPOSE: A wheelchair is provided to easily pass through a narrow path by controlling a width between wheels by rotating wheels together with a cross shaft-connecting which is connected to a wheel. CONSTITUTION: A wheelchair comprises a sheet main body(800), wheels(400a,400b) sheet frames(200a,200b), frame reinforcing supports(300a,300b,300c,300d), and a cross shaft connected to the wheels. The seat main body is arranged in a center part of a wheel chair. The wheels are in one side and the other side of the seat main body. Connections units with the seat main body of the sheet frame are inserted into the one side and the other side of the seat main body. The frame reinforcing supports horizontally penetrates the sheet frame. The cross shaft connected to the wheel is connected to a shaft of the wheel, and in which the frame reinforcing support is inserted. The wheel rotates around the frame reinforcing support as an shaft together with the cross shaft.
