PROBLEM TO BE SOLVED: To prevent the reduction of air volume and the occurrence of noise even if the back surface of a cleaner body case is formed in circular arc shape and also an irregular surface is formed. SOLUTION: In an air cleaner in which the air sucked into the cleaner body case 2 from an air suction port 9 is cleaned and blown out from a discharge port 4 to the outside of the cleaner body case 2, the back surface being one side surface of the cleaner body case 2 is formed in a circular arc shape projecting outside and the back surface is formed in the irregular surface 12, and a fan 28 is surrounded with a fan casing 29 provided in the cleaner body case 2 and communicates with the discharge port 4 and the back surface, and a rib 14 located in the vicinity of the outer diameter of the fan 28 and erected at the inner side of the cleaner body case 2 than the irregular surface 12 is formed at the back surface. Therefore, the air is prevented from flowing between the fan 28 and the one side surface of the cleaner body case 2 from the outside of the fan along the one side surface of the cleaner body due to the rib. |
