Abstract
An air cleaner device includes a filter element for filtering air and being disposed in a housing. The device comprises a hollow housing having an inlet portion, an outlet portion, and a flow passage therein which is communicated with the inlet portion and the outlet portion. The housing also has an opening which is disposed between the inlet portion and the outlet portion, and communicates the flow passage with the exterior of the housing. A filter element is inserted through the opening into the flow passage, disposed between the inlet portion and the outlet portion, so as to filter the air flowing through the flow passage. A lid is mounted on the housing for covering the opening. A resilient urging member allows the lid to be urged toward the housing so as to close the opening, and the resilient urging member allows the lid to be moved away from the opening when this urging is released. With this construction, by moving the lid, urged by the resilient urging member, to open and close the opening in the housing, the filter element can be easily inserted into and removed from the housing through the opening.
