Abstract
A ventilation controlling apparatus using a slide door made of a flexible film member to solve imperfect slide action attributable to film member rigidity degradation on the fringe of an aperture. The slide door is movably disposed inside a casing which forms an air passage, and the slide door is composed of the flexible film member provided with an air-circulation aperture. Ventilation of the air passage is controlled by varying an area of blending or connection between the aperture and the air passage in accordance with movement of the slide door. A rigid support member is fitted around the fringe of the aperture on the film member, thereby enhancing rigidity of the aperture fringe.
