Abstract:
1. Traveling device comprising: a main casing; a left suction seal disposed on a left side of the main casing; a right suction seal disposed on a right side of the main casing; a left drive wheel disposed in the left suction seal for moving the main casing in a traveling direction; and a right drive wheel disposed in the right suction seal for moving the main casing in the traveling direction, wherein said main casing has a traveling axis line at a center thereof in parallel to the traveling direction; said left and right suction seals are driven to rotate around rotation axes thereof so that the rotation axes are substantially symmetrically arranged on right and left sides of the traveling axis line; said left suction seal is arranged so that the rotation axis thereof is away from the traveling axis line by a distance equal to a distance between the rotation axis of the right suction seal and the traveling axis line; each of said left and right suction seals is formed in a shape so that a furthest perimeter edge thereof is away from the rotation axis by a distance greater than a distance between a nearest perimeter edge thereof and the rotation axis; and said left and right drive wheels are situated on the rotation axes.
