To provide a traveling device capable of preventing uneven wear of an upper roller for supporting an upper side part of a crawler with a simple structure.
The crawler 34 endlessly connected with a plurality of track block bodies 41 by a connecting member 42 is wound and mounted on a frame for traveling to freely move and circulate. The upper roller 37 for supporting the upper side of the crawler 34 from a lower side is rotatably journaled to an upper part of the frame for traveling. In the upper roller 37, a plurality of projecting parts 47 to rotate a roller main body 46 by being engaged to the connecting member 42 by moving of the crawler 34 are projectingly provided from the roller main body 46 for movably supporting the track block bodies 41 of the crawler 34.
