A wheel unit includes a motor, a pinion gear fixed to a rotating portion of the motor, a wheel including an annular ground surface and rotating around a final gear support shaft, and a final gear disposed on one side in an axial direction with respect to the wheel. The wheel unit further includes a speed reduction mechanism which decelerates rotation of the pinion gear and transmits the rotation to the final gear and a gear case which accommodates the pinion gear. When viewed from the axial direction, the final gear support shaft and the motor shaft are disposed in different positions. An initial stage composite gear of the speed reduction mechanism meshes with the pinion gear. The initial stage composite gear is supported by the final gear support shaft such that the initial stage composite gear and the final gear are rotatable relative to the gear case.
