Abstract
A traveling carriage includes driven wheels for running on a running surface. For changing a running direction of the traveling carriage, the driven wheels are raised and separated from the running surface by an elevator mechanism and then turned to change their steered directions by a steering mechanism. While changing the steered directions of the driven wheels, the traveling carriage is fixed relative to the running surface by simple-structured leg-like members. Further, the driven wheels have their own turning centers to turn thereabout for changing their steered directions. This realizes a reduced turning radius for each of the driven wheels. Further, since the driven wheels are turned in phase with each other, the stable running of the traveling carriage is ensured.
