Driving rollers are included in the pair of drive force transmissions. Driving rollers transmit drive force to a main wheel. The main wheel includes driven rollers. The pair of drive force transmissions are rotatable about a rotation axis. The pair of carriers accommodate at least a portion of the decelerators. The pair of carriers oppose each other in an axial direction along the rotation axis. The pair of carriers include a first carrier and a second carrier that are directly or indirectly coupled by the at least one coupler.
