PROBLEM TO BE SOLVED: To provide an air stream peeling-off suppression structure for a movement body capable of suppressing peeling off of the air stream from a leading part of the movement body by a simple structure. SOLUTION: The peeling-off suppression part 6 suppresses peeling off of the air stream F from the leading part of the vehicle 2 by leading the air stream F colliding to a vehicle body end surface 3a of the vehicle 2 to vehicle body side surfaces 3b, 3c and a vehicle body upper surface 3d of the vehicle 2. When the vehicle 2 travels in an X axis direction, the air stream F colliding to the vehicle body end surface 3a passes through a clearance partΔ<SB>1</SB>between an inner side fin part 7a and an outer side fin part 7b. Therefore, the air stream F is led 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 stream F flows along these surfaces. As a result, the air stream F collided to the vehicle body end surface 3a is suppressed from being peeled off and an appearance cross section of the leading part of the vehicle 2 is suppressed from being increased. Pressure variation generated when the vehicle 2 intrudes into a fixed structure body such as a tunnel is reduced. COPYRIGHT: (C)2009,JPO&INPIT |
