Abstract
A driving device for a carriage includes a motor, a speed reducer, and a mecanum wheel. The speed reducer decelerates the power input from the motor and outputs a decelerated power. The mecanum wheel is rotated by the decelerated power output from the speed reducer. The speed reducer includes a speed reducing unit, a carrier, and a case. The speed reducing unit receives the power from the motor. The carrier supports the speed reducing unit. The case is rotatable relative to the carrier. The mecanum wheel is fixed on the case or the carrier.
