Abstract: An engine-driven working machine has an engine unit, a housing, and a vaned rotor. An air passage is defined between a crankcase of the engine unit and a bottom wall of the housing. The air passage has an inlet opening provided near an oil seal on a drive-side shaft, and an outlet opening provided in a magnet-side wall so as to face the vaned rotor. Rotations of the vaned rotor cause airflow from the inlet opening through the air passage to the outlet opening.
