Abstract
A damper device for use in an air conditioner of a vehicle, which changes over the direction and volume of an air flow in an air conditioner when a screen (41) is slid. The screen has a laminated resin coat layer (8) or the resin film layer (5), and the cloth layer (7). The resin film layer (5) has excellent tensile and bending strength, and exhibits anti-creep properties, and further it inhibits elastic deformation or plastic deformation (initial elongation) that is the weak point of the cloth layer (7). The cloth layer (7) makes up for the tear strength that is a weak point of the resin film layer (5). The resin coat layer (8) makes up for anti-abrasion and low frictional properties that are weak points of the cloth layer (7). Each layer is provided with flexibility, moisture resistance and heat resistance, so that the entire arrangement of layers provides the necessary characteristics required for the screen.
