Abstract
There is provided a refuse-trapping cover for a portable working machine, which is capable of reducing the deterioration of the engine-cooling performance of the cooling fan that may be caused by the fibrous sawdust of a palm tree. The refuse-trapping cover includes a frame () having a plurality of open windows (-) and attached to the outer casing () of a chain saw () to thereby cover the air inlet slits (), and a mesh member () integrally fixed to the frame () to thereby cover open windows (-). The frame () is constructed to have predetermined dimension and configuration, and the mesh member () is fixed to a predetermined location of the frame () to thereby provide a sufficient space (S) between the mesh member () and the outer casing () to avoid the mesh member () from being adsorbed onto the outer casing ().
