PURPOSE:To contrive a reduction of material cost by making assembling characteristics favorable, by a method wherein a claw part is formed on an opening and closing plate of a sliding type air vent, a protrusion and a side wall provided on a wall surface constituting a ventilation circuit is secured slidably on the claw part and provided a stepped difference in a protruding direction of the protrusion. CONSTITUTION:An opening and closing plate 13 of a sliding type air vent is held slidably on a protrusion formed on a wall surface 7 by a claw part 14, whose opening and closing positions are secured reliably at optional positions by getting over a stepped difference 10 formed on the protrusion in a protruded direction by the claw 14 through its elasticity. Parts, therefore, such as a holding plate which was made necessary hitherto becomes unnecessary. |
