Abstract
A motor-assisted single-wheel cart is provided with a motor for generating an assisting power in response to an operation force when operating an operation handle by a human hand, and a power transmission mechanism for transmitting an output of the motor to an axle. The motor is arranged rearwardly upwardly of the axle so as to be positioned within a space surrounded by an upper horizontal member and a lower member positioned below the upper horizontal member constituting a vehicle body frame constituting the cart as viewing the vehicle body frame from a side surface thereof. The power transmission mechanism has a first speed reduction mechanism arranged near the motor, a second speed reduction mechanism arranged near the wheel and a transmission shaft for connecting them. The transmission shaft is inserted to the first and second speed reduction mechanisms so as to be capable of being drawn out.
