Abstract
A cyclone separator having a circular cross section is arranged upstream of an air filter. An introduction passage extends from a branch air inlet, which is provided at a position displaced from a main passage, to the cyclone separator. A margin space where at least part of air introduced in the introduction passage flows is formed in the introduction passage before the cyclone separator. A swirl flow occurring in the cyclone separator starts at this margin space.
