Description of the Related Art Conventionally, there are self-propelled wheelchairs used by persons with disabilities, such as a manual type, an electric type, and a combination of electric and manual type. There is Japanese Patent Application No. 2001-338768 "Wheelchair driven by leg force". However, the steering performance is not sufficient when changing directions in a narrow room. In addition, it is difficult to obtain optimum pedaling force because the distance from the seat to the pedal varies depending on the physical constitution of the user. In addition, when moving from a bed or other places, the position of the pedal is at the front, which hinders the movement of the foot when getting on and off.

Generally, a wheelchair is driven by rear wheels and takes the form of front wheel steering. However, a steering method with a small turn is required. There is a need for a system that prevents the pedals from getting in the way when getting on and off. There is a demand for a system that allows the seat to move back and forth according to the physical constitution of the user. The present invention aims to improve the function of a conventional foot-operated wheelchair to not only perform rehabilitation, but also expand the range of application to secure a range of action for persons with disabilities.

ドからの移乗などに利便性が高い。Since the present invention is constructed as described above, it has the following effects. Since a person using this wheelchair mainly acts indoors and cannot take a sufficient space in many cases, the steering means with a small turning effect according to the present invention has an effect of assisting the action. Since the seat can be moved back and forth, the distance between the seat and the pedal can be changed to obtain the optimum driving force (pedaling force) according to the physique. Also, since the seats can be rotated, the pedals do not obstruct the movement of the feet when getting on and off, which is highly convenient for transferring from the bed.
