According to the second aspect of the present invention, an elevating mechanism is provided on the wheelchair main body having the left and right front wheels, and the elevating mechanism is extended in the front-rear direction and the lower surface is curved in a downwardly bulging shape. The pair of left and right swing legs and the left and right rear wheels are attached to each other, and the left and right swing legs and the left and right rear wheels can be moved up and down by a lifting mechanism. The right and left front and rear wheels are linked with the lifting and non-grounding action of the left and right front and rear wheels, and the left and right front and rear wheels are lowered and touched with the lifting and non-grounding action of the left and right swinging legs. Because of the interlocking, the vertical movement distance of the left and right swinging legs can be made as small as possible, simplifying the operation of changing the usage pattern, and also ensuring the function of a rocking chair well. it can.
