WIPO Patent Application WO/2022/255112

A1

The objective of the invention is to improve running performance. A drive wheel 103 comprises a first input shaft 34A and a second input shaft 34B, a first output shaft 40A and a second output shaft 40B, a first spur gear mechanism 13A that transmits the rotational force of the first input shaft to the first output shaft, a second spur gear mechanism 13B that transmits the rotational force of the second input shaft to the second output shaft, a wheel 16 connected to an axle 37, a pivot shaft 35 that rotatably support the wheel through the axle, a first power conversion mechanism 15A that transmits the rotational force of the first output shaft to one end of the axle, a second power conversion mechanism 15B that transmits the rotational force of the second output shaft to the other end of the axle, a first slide mechanism 25A that maintains the transmission of rotational force to one end of the axle and permits the movement of the one end of the axle along the extension direction of the first output shaft, a second slide mechanism 25B that maintains the transmission of rotational force to the other end of the axle and permits the movement of the other end of the axle along the extension direction of the second output shaft, and an elastic member 26 that elastically supports the axle.
