WALL SURFACE TRAVELING MACHINE

PURPOSE:To eliminate a magnet which makes no contribution to attraction force, in a traveling machine provided with a magnet which has magnetically attracting characteristics one wall surface whose crawler is formed out of magnetic substance, by making the magnet face a wall surface to be fixed on a traveling machine body, and sliding the crawler between the magnet and the wall surface. CONSTITUTION:Plural inductive wheels 3 are mounted on a traveling machine body 1 so as to rotate freely through an axle 2, and a thin crawler 6 with high tensile strength is wound around their peripheries. At this time, the crawler 6 and the inductive wheel 3 are made to mesh with each other by engaging protrusions 8 in the inductive wheel 3 with holes 7 in the crawler 6. Also, the magnet 4 is mounted on a body 1, facing a wall surface, and is arranged inside the crawler 6, by which the crawler 6 is made invade the part between the magnet 4 and the wall surface 5. Moreover, small roughness is provided in a contact surface A of the crawler 6 with the wall surface 5 to increase frictional resistance, and a contact surface B with the magnet 4 is made smooth and frictional resistance is decreased by using lubricant. It is thus possible to travel the whole traveling machine in an attracted condition on the wall surface with the rotation of the crawler 6.
