PROBLEM TO BE SOLVED: To provide a guide cover which evenly diverts cooling wind for a forcedly-air cooled engine to the outer periphery of a cylinder and a cylinder block. SOLUTION: While the main blowout port of the cooling wind for a cylinder, which is provided to a fan cover, is provided face to face with almost the front of the cylinder of the forcedly-air cooled engine, the sub-blowout port of the cooling wind for the cylinder block is provided below the position which is symmetric with the main blowout port of the cooling wind about a plumb line passing through a crankshaft. Then the cooling wind guide cover consists of a top cover part and a cylinder cover part, both of which can be integrated with each other by fitting. The top cover part supplies wind from the main blowout port for the cooling wind to the rear of the cylinder so that the wind turns around the cylinder. The cylinder cover supplies the cooling wind from the sub-blowout port for the cooling wind along the outer periphery of the cylinder block, and supplies a required amount of cooling wind to the opposite side of the fan of the cylinder while cooling the cylinder block.
