PROBLEM TO BE SOLVED: To provide a flap structure of a motor fan shroud which can be mounted within an engine room, without enlarging the installation space ahead of and behind a vehicle. SOLUTION: In the flap structure of the motor fan shroud, an opening portion 4a is arranged at a position apart from a fan ventilation hole 3 in a shroud wall 2 of the motor fan shroud 1, and a flap 5a is provided for opening or closing the opening portion 4a by the ram pressure of wind when the vehicle is running. The opening portion 4a can be opened or closed freely by rotating the flap 5a toward the inner side of the motor fan shroud 1 from the shroud wall 2. COPYRIGHT: (C)2006,JPO&NCIPI
