ABSTRACT:
A debris entry preventing member A of an air-cooled type internal combustion engine E is made of a flexible sheet material as a whole and includes a mounting portion 7 to be mounted on a mounting component 15, which will be attached to the internal combustion engine E, and a debris capturing portion 4 having a multiplicity of ventilation holes 5. When the mounting component 15 is attached to the internal combustion engine E, the debris entry preventing member A is mounted thereon together with the mounting component 15 so that the debris capturing portion 4 covers a cooling air intake port 11. As a result, a job for mounting the debris entry preventing member can be easily carried out, no screws and the like are needed for mounting it, the debris entry preventing member can be easily manufactured and its cost can be reduced. Accordingly, the debris entry preventing member contributes to the reduction of weight of the air-cooled type internal combustion engine and a portable working machine on which the air-cooled type internal combustion engine is mounted as a power source.
