<p>PROBLEM TO BE SOLVED: To provide an in-tube traveling device for traveling in a tube easily at low costs. SOLUTION: An in-tube traveling device is provided with a first and a second moving bodies 1 and 2 elastically connected by a connecting body 3, a first pressing means arranged in the first moving body 1 and a second pressing means 5 and a driving means 6 arranged in the second moving body 2. The in-tube traveling device is moved by distance equivalent to the strokes of the diving means 6 so as to realize automatic traveling in a tube. Cornering traveling of the in-tube traveling device in a curved tube part is realized by proper bending and displacing the connecting body 3 in the curved tube part. Thus, without providing a traveling wheel or a steering mechanism as in the conventional case, traveling in the tube and cornering traveling in the curved tube part are realized and the structure of the device is simplified and costs are reduced.</p> |
