PROBLEM TO BE SOLVED: To provide a cyclone air cleaner in which intake efficiency is increased without increasing the size. SOLUTION: This cyclone air cleaner 10C comprises an air cleaner case 20, a filtration part 40, an air reversal part 50C, a swirl vane part 60, and a vane rotating mechanism 70. Since a projected part 51 is formed in the cyclone air cleaner 10C, air can be guided from the lower part 23 of the case smoothly to a filter element 44 and an air outlet 43a, and the intake efficiency can be increased. Also, since eight guide walls 53 and pre-guide walls 54, 54 are formed, the air can be guided rapidly to the filter element 44 and the air outlet 43a along the pre-guide wall 54 and the guide walls 53. When the rotational speed of an engine exceeds a specified value, the swirl vane 63 is rotated to increase the intake efficiency by the sucking action and the extruding action of the swirl vane 63 without increasing the size.
