A wall surface suction-type travel device is configured to travel on a wall surface while being suctioned on the wall surface. An intermediate chamber communicates with decompression chambers facing the wall surface. A suction device sucks in air from the intermediate chamber to decompress the intermediate chamber. Principal communicating parts allow the decompression chambers to communicate with the intermediate chamber. Secondary communicating parts allow the respective decompression chambers to communicate with the intermediate chamber. Valves face openings of the respective principal communicating parts. An area of an opening of each of the secondary communicating parts is smaller than an area of the opening of a corresponding one of the principal communicating parts. On condition that pressure in one of decompression chambers gets higher than pressure required for wall surface suction, a consequent difference in pressure between the one of decompression chambers and the intermediate chamber causes a corresponding one of the valves to close the opening.
