PURPOSE:To simplify the construction of an air spoiler and reduce labor for maintaining and inspecting the air spoiler by introducing pressure generated around a travelling car body into an expansible air tight chamber to vertically moving a movable portion of the air spoiler. CONSTITUTION:An air spoiler 1 is constituted to receive an expansible air tight chamber 30 between a main body bed seat 10 forming a wedge-like case and a main body movable portion 20 connected pivotably to a front edge hinge portion 11 of the main body bed seat. Pressure generated around a car body of a travelling vehicle is utilized for a drive means of the air spoiler so that said pressure around the car body is introduced into said chamber 30 to move vertically said main body movable portion 20. |
