PROBLEM TO BE SOLVED: To provide an air cleaner device which materializes both reduction in air intake noise and facilitation of maintenance work by simplifying an inside structure. SOLUTION: The inside space 11 of an air cleaner device 1 contains a first opening for communicating to a flow passage of a primary duct 3 and a second opening for communicating to a flow passage of a secondary duct. A partition wall 6 partitions the inside space 11 into a first area 16 including the first opening and a second area 17 including the second opening and communicating to the first area 16. An air filter 7 is provided to a communication part between the first area 16 and the second area 17, and separates the first area 16 and the second area 17. A separation plate 8 extends from the partition wall 6 to oppose the first opening and partitions the first area 16 into the upstream area 18 including the first opening and the downstream area 19 facing to the air filter 7, wherein a communication passage 20 for communicating between the upstream area 18 and the downstream area 19 is formed. The flow passage cross section of the communication passage 20 has an area substantially equal to that of the primary duct 3 has. COPYRIGHT: (C)2006,JPO&NCIPI
