PROBLEM TO BE SOLVED: To provide a register capable of switching and adjusting a spot blast and a mild blast by a simple operation.SOLUTION: On an upper stream side of a rotary louver, a pair of diffusion fins 10 and 11 for diffusion are pivoted for allowing opening/closing rotation of chord-like edge parts on both sides in a ventilation path 8. The pair of diffusion fins 10 and 11 are arranged on both sides of a central axis parallel to the ventilation direction of the ventilation path 8, and support axes 10b and 11b of the diffusion fin are arranged perpendicular to the central axis of the ventilation path 8. The support axes 10b and 11b of the diffusion fin are interlocked with a rotational operation mechanism 20 provided with an operation dial 21. The rotation operation mechanism 20 rotates the pair of diffusion fins 10 and 11, according to rotation of the operation dial 21, within a range from a state parallel to the ventilation direction of the ventilation path to when the chord-like edge part on both sides in the ventilation path 8 is closed, for constriction in a state perpendicular to the ventilation direction, from the state parallel to the ventilation direction of the ventilation path. |
