A speed reducer which decelerates rotation input from a motor and outputs decelerated rotation to a wheel includes: a case fixed to a carriage body; an input portion for receiving the rotation input from the motor; an output portion for outputting the rotation to the wheel; and a speed reducing mechanism at least partially housed in the case and configured to decelerate rotation of the input portion and transmit the decelerated rotation to the output portion. The maximum outer radius of the case from the rotation axis of the output portion is larger than the radius of the wheel, and the minimum outer radius of the case from the rotation axis of the output portion is smaller than the radius of the wheel
