An air-conditioning register includes a cylinder-shaped retainer having opposite
inner surfaces, a fin assembly including a plurality of fin members disposed in
the retainer, a first connector connecting the fin members, a second connector,
and a guide guiding the second connector on a predetermined track. The fin members
includes paired fin members disposed in proximity to the opposite inner surfaces
of the retainer, at least one of the paired fin members swinging by a swing angle
smaller than that of all of the other fin members, and functioning as a dummy fin
member keeping a constant angle independently within a predetermined swing-angle
range where all of the other fin members swing. The second connector connects the
dummy fin member and all of the other fin members while absorbing a swing-angle
difference between the dummy fin member and all of the other fin members.
