が課題である。In the method described in the prior art, the manual wheel control method makes it difficult to judge the left-right balance for persons with impaired motor nerves and persons with cranial nervous system disorders. There is a difficult defect, and the method of controlling the motors for the left and right wheels has a complicated structure, which leads to an increase in production cost. The challenge is to simplify the mechanism and structure as much as possible.

する。In order to solve the above problems, according to the present invention, a steering shaft having a steering lever attached to an upper end thereof is connected to a shaft of a fork on one side of the left and right free wheels,
Also, the bearing that passes through the steering shaft is fixed to the vehicle body. (Fig. 2) Also, the fork shaft and the steering shaft are connected to each other by using a joint or the like so that they can be separated from each other, and the steering shaft can be replaced on either side of the vehicle body by bearings on both sides of the vehicle body. There is also an example in which a mounting hole is provided. (FIG. 3) The steering lever is attached to the steering shaft so that the direction of the free wheel and the direction of the steering lever can be freely adjusted, and the steering lever can be attached to the steering shaft at an arbitrary rotation angle.

る。(図3)BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described based on examples. A steering shaft 5 is connected and fixed to the upper end of a fork shaft 3 which is fixed to a fork 2 to which a universal wheel 1 is attached and which is vertically and rotatably held on a side surface of a wheelchair, and the steering shaft is vertically attached to a vehicle body A by a bearing 4. . A steering lever 6 is attached to the upper end of the steering shaft 5 at an arbitrary rotation angle with respect to the steering shaft 5. (FIG. 2) As another example, the fork shaft 3 and the steering shaft 5 described above are connected via a joint 7, and the joint 7 is configured such that the connector 7a and the connector 7b mesh with each other, and the upper end of the fork shaft 3 is connected. A connector 7b is molded on the steering shaft 5, and a connector 7a is molded on the lower end of the steering shaft 5. Further, the connector 7b is molded on both left and right fork shafts, and the bearing 4 is passed through the steering shaft 5. It can be mounted on either side of the wheelchair. (Figure 3)
