Abstract
An air cleaner includes closure means comprised of a partition wall integrally formed on one side of a filter member, which closure means will selectively shut either a first air-intake port for sucking outside air into a filtration room or a second air-intake port to suck air into the filtration room through an engine room. One of these first and second air-intake ports is selectively closed by a partition wall by turning the positioning of the filter member.
