Abstract
A drive mechanism includes a rotatable steering unit, a wheel supported by the steering unit, a drive member rotating about an axis extending along a center axis of the steering unit, an output shaft located at an offset position from the center axis of the steering unit and transmitting rotational force of the drive member to the wheel. The drive member includes a first drive unit driven in a forward rotation direction and a second drive unit driven in a reverse rotation direction and located coaxially with the first drive unit. The output shaft includes a first output unit to which driving force is transmitted from the first drive unit, and a second output unit to which driving force is transmitted from a conversion unit for converting rotation of the second drive unit, is restricted by both the output units, and transmits rotational force obtained from the output units to the wheel.
