  • Japanese Laid-Open Patent Publication No. 2005-344555 describes an air cleaner that includes a cap provided integrally with an inlet duct. When the cap is attached to a case, the opening of the inlet duct on its downstream side and the opening of an inlet of the case communicate with each other.
  • an inlet of a case is connected to an inlet duct separately provided from the case, so that a step is likely to be formed on the inner peripheral surface of the connected portion. This step may cause turbulence of airflow, resulting in an increase in pressure loss.
