Abstract
An electric wheelchair has two front wheels and two rear wheels and is thus four-wheeled. The wheelchair has a tread between the rear wheels, which is smaller than a tread between the front wheels. It also has a floor disposed between the front wheels and rear wheels and having side ends positioned externally of outer surfaces of the rear wheels. Thus, a crew can drive the wheelchair using the front body width of the wheelchair as a reference while paying little attention backward. A motor and a reduction gear as components of a rear wheel driving mechanism are laid compactly on a rear wheel axle one over the other. This reduces the body length and enables down-sizing of the wheelchair.
