Document Type and Number:
WIPO Patent Application WO/2021/065421
Kind Code:
The purpose of the present disclosure is to provide a passage opening/closing device that is capable of suppressing self-excited vibration of a slide door while suppressing a degradation in the manufacturability of the slide door. This passage opening/closing device comprises: a case (12) in which an opening edge part (23) that forms an opening section (22a) of an air passage (22) is provided; and a slide door (50) that is slidably disposed inside the case and opens/closes the opening section. The slide door includes a door end section (52A) that constitutes one end section in the door movement direction of the slide door and faces the opening edge part when the slide door is displaced to a closing position for closing the opening section. The opening edge part includes a door facing wall section (126) that faces the door end section when the slide door is displaced to the closed position and that forms a gap flow passage (G) extending in the door movement direction between the door end section and the door facing wall section. In the door end section and the door facing wall section, a gap between the door end section and the door facing wall section becomes smaller toward the downstream side of an air flow so that the gap flow passage serves as a tapered flow passage.
