PROBLEM TO BE SOLVED: To provide a wind direction regulating device wherein strict manufacture precision is not demanded, a desired operation force is exerted on a louver, the louver can be stably held at a frame body, and besides the louver can be easily and smoothly mounted on the frame body. SOLUTION: The wind direction regulation device is provided with a first frame body (2) and a second frame body (3), and rotary axes (5a) of a longitudinal louver (5) are elastically held at a plurality of elastic holding pieces (3a) extending from the front end of the second frame body (3) toward the directions of air discharge openings. Ribs (2e) corresponding to the installation distances of the elastic holding pieces (3a) are formed on the inner wall surface of the first frame body (2). When the second frame body (3) is fitted in the first frame body (2), the rib (2e) is inserted as the rib is brought into close contact along at least one side of the elastic holding piece (3a). The rib (2e) brings the one side or the two sides of each of the elastic holding pieces (3a) into pressure contact in a direction crossing the rotary axis (5a) of the longitudinal louver (5), and the elastic holding piece (3a) is brought into elastic contact with the rotary shaft (5a) of the longitudinal louver (5).
