Abstract
Provided is a haulage vehicle having an air cleaner that is realistic from the viewpoints of fabrication steps and cost aspect. An air cleaner () arranged in a haulage vehicle is provided with a swirling flow generator (), a separator () and an outer cylindrical casing (). The swirling flow generator has a fixed shaft () and a plurality of guide blades () arranged and shifted from one another over a predetermined angle in a direction in which the guide blades rotate about the fixed shaft, and by the plurality of guide blades, a swirling flow of cooling air is generated. The separator has a flange () attached on and along an inner peripheral wall of the outer cylindrical casing (), an inner cylindrical member () arranged on an outer edge of a center bore of the flange, and a collection pocket (). Dust contained in the cooling air is taken by the swirling flow into a space between the inner cylindrical member and the outer cylindrical casing and is allowed to accumulate in the collection pocket.
