PURPOSE:To prevent the damage of members connecting links by placing a stopper piece on a knob, which contacts a specified rotation control member at a location where lateral louvers are moved to their maximum rotating angles. CONSTITUTION:Sliding a knob 15 in the right and left directions causes a spacer 12 to move along a stay 11 and a central vertical louver 8c connected with a ratchet 24 and vertical louvers 8a, 8b, 8d, 8e connected with the louver 8c through a link 10 are changed in their set angles to be able to control the right and left pointing directions of conditioned air transferred from a discharge hole 18. When the knob is moved in the upward direction, a central lateral louver 14b and lateral louvers 14a, 14c connected with the louver 14b through a link 16 are changed in their set angles to guide conditioned air transferred from a discharge hole 8 upwards. At that time, when the louvers 14a, 14b, 14c are moved to their maximum angles, an upper stopper piece 27 placed on the knob 25 contacts the spacer 12 to stop the rotation of the knob 25. Thereby, the damage of members supporting the link and the operation inability of the louvers caused by the crash of the end parts of the link to a housing are able to be prevented.
