Abstract
A cleaner casing is fitted to a fan casing for covering an air cooling fan for an engine. A cleaner chamber is formed between the fan casing and the cleaner casing. The cleaner chamber accommodates therein a cylindrical filter element. The filter element purifies air which will becomes an intake air for the engine. In an outer periphery of the cleaner chamber, a swirling passage is formed. An air outside the fan casing is captured into the switching passage through a suction opening. The swirling passage allows the air to be passed onto a hollow portion of the filter element after the air has been swirled around the filter element thereby.
