The present invention relates to a gear apparatus capable of changing directions. The present invention is configured to include a body; and a rotary feeding part installed on the bottom of the body to be rotatable and changing feeding directions of rotary wheels via a built-in gear part. The present invention controls the rotary wheels, installed in a transportation truck or the like disposed on lacking tracks to be movable, in a desired rotation direction, thereby moving without interference with respect to a radius of rotation and orthogonally moving in a case that changing directions is not necessary, and enhancing space availability as well as performing free movement such as orthogonal, diagonal, and zigzag movement on coordinates by transmitting driving power to each of four wheels. |
