<P>PROBLEM TO BE SOLVED: To provide an air flow separation suppression structure of a moving body that suppresses separation of an air flow from the head of the moving body by a simple structure. <P>SOLUTION: A separation suppression part 6 guides an air flow F from the vehicle-body end surface 3a of a vehicle 2 to the vehicle-body side surfaces 3b, 3c and the vehicle-body upper surface 3d of the vehicle 2, thereby suppressing separation of the air flow F from the head of the vehicle 2. When the vehicle 2 travels in the X axis direction, the air flow F toward the vehicle-body end surface 3a collides with a guide part 9 and the air flow F, having collided with the guide part is guided to the separation suppression part 6 by the guide part 9. Thus, the air flow F is guided from the vehicle-body end surface 3a to the vehicle-body side surfaces 3b, 3c and the vehicle-body upper surface 3d and the air flow F flows along the surfaces of the vehicle-body side surfaces 3b, 3c and the vehicle-body upper surface 3d. As a result, this structure suppresses an increase in the apparent cross-sectional area of the head of the vehicle 2 and reduces a pressure variation occurring when the vehicle 2 runs into a tunnel or the like. <P>COPYRIGHT: (C)2012,JPO&INPIT |
