An electric wheelchair (1) has two front wheels (2, 2) and two rear wheels (3, 3) and is thus four-wheeled. The wheelchair (1) has a tread (TR) between the rear wheels (3, 3), which is smaller than a tread (TF) between the front wheels (2, 2). It also has a floor disposed between the front wheels (2, 2) and rear wheels (3, 3) and having side ends positioned externally of outer surfaces (3a, 3a) of the rear wheels (3, 3). Thus, a crew can drive the wheelchair (1) using the front body width of the wheelchair (1) as a reference while paying little attention backward. A motor (21) and a reduction gear (22) as components of a rear wheel driving mechanism are laid compactly on a rear wheel axle (16) one over the other. This reduces the body length and enables down-sizing of the wheelchair (1). <IMAGE> |
