塵装置。[Claim for Utility Model Registration] A fan cover 1 is arranged on one side of the engine E, and a dust cover 3 with a large number of air intake ports 5 is made to face an opening 2 formed in the center of the fan cover 1. In a dust prevention device for a forced air engine, a dust cover 3 is interlocked and connected to a rotating shaft 4 of an engine E, and cooling air is taken in by a cooling fan 6 from an air intake port 5 of the rotating dust cover 3 and blown onto the engine E. At least the outer peripheral part 7 of the dust cover 3 is made to protrude outside the fan cover 3 from the cover outer end part 8 on the outside of the opening 2, and the edge 10 of the outer peripheral part 7 is connected to the dust cover 3. A dustproof device for a forced air engine, characterized in that it is configured to be spaced outward from a rotational fitting gap 12 between the opening 2 and the opening 2.
