PROBLEM TO BE SOLVED: To provide a cyclone air cleaner that can obtain higher dust collection efficiency than a conventional one. SOLUTION: In this cyclone air cleaner including a filter element, a cleaner case that contains and holds the filter element and that has element containing room with an opening at one end, a case cover 40 mounted on the cleaner case by covering the opening, and a dust cover 80 mounted inside the case cover, dust cover support ribs 42 and plate-like dust cover mounting guides 44 are provided. Each of the ribs 42 is placed on the inner bottom surface of the case cover 40 and has a shape of blade curved in the same direction as that of the flow of swirl air flow. Each of the guides 44 extends vertically from the inner bottom surface of the case cover 40 and inclines to the same direction of that of the flow of the swirl air flow within the element containing room against the tangent direction of a peripheral surface of the dust cover 80 and is in contact with the peripheral surface of the dust cover 80.
