An air-conditioning register includes a cylinder-shaped retainer, a
plurality of horizontal fins, a connecting rod, an actuating member, and
a moving member. The cylinder-shaped retainer has opposite upper and
lower walls and opposite side walls, which form an outlet opening and an
air passage. The horizontal fins have a swing shaft, respectively, and
are disposed pivotally about the swing shaft within the retainer. The
connecting rod connects the horizontal fins. The actuating member
actuates the connecting rod to swing the horizontal fins synchronously
with each other. The moving member enables the swing shaft of at least
one of the horizontal fins to move back and forth with respect to the
retainer depending on a swing angle of the horizontal fins with respect
to a horizontal plane.
