ABSTRACT:
There is provided a filter element of an air cleaner unit of an open element type which prevents turbulent flow from arising to lower the air suction sound and avoid the loss of sucked air by the turbulent flow. In a filter element in which a major diameter side opening of a tapered cylindrical filter member with a zigzag shaped cross section is connected to a suction duct of an engine, a rectifying cone member for covering a minor diameter side opening by the root thereof is vertically mounted inside the minor diameter side opening so that its leading end is positioned at or near the end of the major diameter side opening of the filter element, and furthermore, the inner side of a suction duct connecting member formed at the major diameter side opening is shaped like an air funnel.
