A transportation device transports carts including caster wheels along a transportation path without a pit. Side rollers are arranged along the transportation path and at both sides of the transportation path. Springs bias the side rollers into contact with side surfaces of the carts within the transportation path. A motor drives at least some of the side rollers that are arranged at an interval shorter than a length of the carts along the transportation path at the both sides of the transportation path.
