It is intended to provide a moving device with which rotational speed of a prime mover can be reduced and drive force of the prime mover can be efficiently transmitted to a rotary bodies with a simple configuration. An electric wheelchair 1 includes a vehicle body 3, a prime mover 12 provided to the vehicle body 3, a driving rotary body 19 driven by the prime mover 12, and front wheels 5. The front wheels 5 are rotatably provided to the vehicle body 3. The front wheels 5 have a larger diameter than the driving rotary body 19. The front wheels 5 rotates by contact with the driving rotary body 19 in a rotational direction or by magnetic coupling force of the driving rotary body 19.
