Abstract
Provided herein is a driving apparatus for transporting a loaded object, which allows a drive-wheel to always be in contact with the ground even when the ground is uneven. The driving apparatus includes a loading plate (140, 240) on which a loaded object is loaded, a first support (110, 210) connected to a lower portion of one side of the loading plate (140, 240), a second support (120, 220) connected to a lower portion of the other side of the loading plate (140, 240), a hinge (130, 230) configured to connect the first support (110, 210) to the second support (120, 220) in a hinge structure, at least a pair of drive-wheels (160, 260) coupled to both sides of a lower portion of the second support (120, 220), and a driver configured to rotate and drive the drive-wheels (160, 260).
