Abstract

An air-cooled engine is provided, in which a cooling fan assembly for inducing a stream of cooling air and a screen member for covering an axial end face of the cooling fan on a suction side are drivingly mounted on a rotary drive shaft of the engine. A fan casing covering the cooling fan assembly and defining an air flow path for the flow of the stream of cooling air is formed with an air intake opening through which the cooling air is introduced towards the cooling fan assembly and the screen member. A cutter is formed in an outer peripheral portion of the screen member or its neighbor so as to protrude axially close to an inner surface of the fan casing at a position downstream of the cooling air from the air intake opening.
