PROBLEM TO BE SOLVED: To provide a register capable of securing the directivity of good wind according to the rotation of a lateral fin without increasing pressure loss when blowing air. SOLUTION: A front movable louver 3 rotatably journals a central lateral fin 7 to the approximately vertical center of the inside of an air blowoff port 18 in a horizontal direction, while rotatably journaling an upper auxiliary lateral fin 8 in a horizontal direction by approaching an upper wall surface 6a of the inside of the air blowoff port 18, and rotatably journaling a lower auxiliary lateral fin 9 in a horizontal direction by approaching a lower wall surface 6b of the inside of the air blowoff port 18. An auxiliary lateral fin rotary mechanism 10 is connected to rotary axes of the central lateral fin 7, the upper auxiliary lateral fin 8 and the lower auxiliary lateral fin 9. The auxiliary lateral fin rotary mechanism 10 rotates the upper auxiliary lateral fin 8 and the lower auxiliary lateral fin 9 such that the upper auxiliary lateral fin 8 and the lower auxiliary lateral fin 9 push their downstream side edge parts toward the inside of a flow passage when shaking the central lateral fin 7 upward or downward.
