Abstract
An air cleaner may include a filter element and a housing defining an inner space. The inner space may be divided by the filter element into a dust-side air chamber on an upstream side and a clean-side air chamber on a downstream side. Air introduced into the housing may be dischargable via an outlet pipe, to which an air flow sensor is attachable, connected to the clean-side air chamber. The outlet pipe may extend in a direction different from a normal to the filter element. A plurality of ribs may be disposed on an inner surface of a clean-side portion of the housing that defines the clean-side air chamber. The plurality of ribs may extend from a corner portion of the housing toward the filter element and the outlet pipe. A distance between adjacent ribs of the plurality of ribs may decrease in a direction toward the outlet pipe.
