PURPOSE: A device for cleaning a tunnel is provided to uniformly clean a wall of the tunnel to prevent an accident at a traveling and to finely clean a small circular wall having a small radius of curvature. CONSTITUTION: A vehicle is advanced while rinsing water, washing water and air are jetted with a jetting pipe of rinsing water(61). A jetting pipe of washing water(64) and of air(65) after closing every brush(62)(63) in a wall with a uniform pressure, and brushes(62)(63) are rotated at the same time. Since impurities stuck in a wall are separated and cleaned, a stain is not generated by the washing water jetted with the jetting pipe of washing water(64) and a dry state is maintained by removing water remained on the wall with the air. Thereby a cleaning cycle is lengthened because impurities are not stuck in the wall through the vehicle is traveled after cleaning. When the pollutants are accumulated excessively, a quick cleaning is performed by rotating the first brush(62) and the second brush(63) in the opposite direction.
