WHEEL DRIVING DEVICE AND WHEELCHAIR

PROBLEM TO BE SOLVED: To provide a wheel driving device or a wheelchair capable of reducing a torsion angle of a switching member while maintaining a flexible property of the switching member switching the mode of a force transmission mechanism. SOLUTION: A lever 12 extends in a curved shape. The force transmission mechanism 40 is arranged between the lever 12 and a wheel. When the lever 12 is rocked, rotation force is imparted to the X direction with respect to the wheel and the wheel is loosely rolled to the Y direction when the force transmission mechanism 40 is in a first mode, and the rotation force is imparted to the Y direction and the wheel is loosely rolled to the X direction when the force transmission mechanism 40 is in a second mode. The switching member 72 is provided for switching the mode of the force transmission mechanism 40. The switching member 72 includes a linear non-flexible member 721 wherein a rotation angle of one end and a rotation angle of the other end is substantially identical, and a bendable wire 722 having one end fixed to the non-flexible member 721.
