Abstract

An air conditioning thin register includes: a case including a blow-out opening for the air-conditioning air; a pair of auxiliary fins provided in portions of the interior of the case which are adjacent to the second walls; and a main fin extending in the first direction between the paired auxiliary fins, the two auxiliary fins being inclined similarly to and synchronously with the main fin, wherein the second walls include in their downstream portions swelling wall portions swelling in a direction to go away from the ventilation passage, a space surrounded by the swelling wall portions constitutes an inclination space allowing the auxiliary fins to incline more outwardly of the ventilation passage than ordinary wall portions; and the dimension of the blow-out opening in the second dimension and the distance between the ordinary wall portions of the paired second walls are set equal or approximate to each other.
