PROBLEM TO BE SOLVED: To provide an air louver capable of coping with any plate thickness and precluding generation of vibratory sounds and a deformation. SOLUTION: The air louver 10 is to be attached to an air intake 2a provided in the column 2 of a fork lift and is equipped with a frame 11 in the form of a square cylinder, etc., capable of being fitted in the air intake 2a, a flange 12 and the louver 13 provided at the frame 11, and engaging pawls 14a-14c formed at each edge member of the outer surface of the frame 11 and engaged with the air intake 2a, wherein the distances Da, Db, Dc, from the pawls 14a-14c formed on one edge member of the frame 11 to the flange 12 are made different, and the smallest distance Da is set approximately equal to or below the smallest plate thickness Ta of the column 2, while the largest distance Dc is set approximately equal to or over the largest plate thickness Tc of the column 2.
