PROBLEM TO BE SOLVED: To provide a thin register whose air port has a non-rectangular and deformed shape and which can improve directivity of wind produced by swinging of a front fin.SOLUTION: A front movable louver 3 is arranged in the inner front part of an air port 15. In the front movable louver 3, a front fin 7 is supported with a support shaft in a rotatable way, nearly at the center inside the air port 15 and along the longitudinal direction of the air port. The edge part of the air port 15 along the longitudinal direction of the front fin 7 is curved. A first auxiliary fin 8 and a second auxiliary fin 9 are arranged in almost parallel with the tangential direction of the curve and adjacent to at least one side part of the front fin 7. The support shafts of the first auxiliary fin 8 and the second auxiliary fin 9 are supported obliquely to the support shaft of the front fin 7, and each of the auxiliary fins is connected to the front fin 7 with link bars 18 and 19 so as to be rotated synchronously with the front fin. |
