PROBLEM TO BE SOLVED: To provide a travel stabilizing device which can reduce the yaw moment caused by cross wind, to get good travelling stability.SOLUTION: Both ends of a horizontal blade 4b prepared to a rear spoiler 4 are fixed to a trunk lid 3 via right and left vertical blades 4R and 4L. The right and left vertical blades 4R and 4L have a blade profile section, of which the curvature of the leading edge LE is formed larger than that of the tail edge TE, and also have the streamline shape in which the interior surface 4d of the right and left vertical blades 4R and 4L is swelled toward the inner direction. For example, when the right hand side of the moving vehicle 1 is experiencing crosswind, the lift force FL generates on the right vertical blade 4R facing to cross wind toward the inside of the vehicle width direction, but the lift force does not generate on the left vertical blade 4L due to turbulent flow. Therefore, the yaw moment generates in the counter direction to the cross wind, and the yaw moment suppresses turning round moment generated by the cross wind. |
