As a prior art, the Utility Model Application Publication No. 8655 published in 1972, the name of the invention is "Walking Car for Patients" is publicly known. There is a technology in which the forward movement of the wheels on both sides of the wheelchair is caused at the same time as the width is compressed. Utility Model Application Publication No. 18333, the name of the device ``Wheelchair'' is publicly known, and Utility Model Publication No. 73665 published in 1973, the name of the device ``Wheelchair that can be folded into a small volume'' is publicly known.

が難しかつた。 In these known techniques, if both sides of the chair are appropriately compressed, the support rod supporting the lumbar seat will be raised by the X-shaped intersecting rod, narrowing the width of the wheelchair, and at the same time, this lifting movement will be performed by three prongs. The sliding rods fitted on the horizontal frame at the top and bottom are moved forward through the connecting rods, so the wheels on both sides move forward, and the rearwardly protruding wheel parts are housed inside the vehicle body, allowing the tires to move forward. It is possible to remove protruding parts such as Therefore, the wheelchair
This means that it can be transported by reducing its volume. In such a known wheelchair, in conjunction with the forward and backward movement of the sliding rods fitted on the upper and lower sides and changes in the width of the wheelchair, the direction of force is applied almost at right angles, so it is difficult to operate smoothly. It was difficult.
