The present invention provides a crawler traveling device which allows revolution wheels for grounding to reduce the attachment and deposition of mud to upper revolution wheels or support structure parts thereof. The crawler traveling device is configured as follows. An enough space where the revolution wheels (10018) for grounding remarkably ascend and move is formed in the upper part of the revolution wheels (10018) for grounding located near the center of mass of a body (100G). Upper revolution wheels (10025) are supported to the right upper part or near the right upper part of the other revolution wheels (10018) for grounding, which are supported to a movement balancing frame (10027) through shafts together with the revolution wheels (10018) for grounding located near the center of mass of the body (100G), through shafts. |
