Abstract

See full text

The passage opening and closing device includes a casing in which an opening edge forms an opening of an air passage, and a sliding door slidably movable inside the casing to open and close the opening. A door end part of the sliding door faces a door facing wall of the opening edge when the sliding door is positioned at a closed position where the sliding door closes the opening. A gap flow-path extending in the door moving direction is formed between the door facing wall and the door end part. A distance between the door end part and the door facing wall decreases downstream in air flow in the gap flow-path so that the gap flow-path is a convergent flow path.
