PROBLEM TO BE SOLVED: To suppress vibration at both end parts of a moving direction of a slide door, without using separate parts. SOLUTION: This air passage opening/closing device is provided with the slide door 50 to open/close an air passage 16 by a platelike part 51 arranged to be slidably movable in a case 11 forming the air passage 16 and a guide groove 53 for guiding moving of a platelike part 51 by a windward side wall part 53a formed in the case 11 to be extended in the moving direction of the platelike part 51 on a windward side as compared with the platelike part 51 and a leeward side wall part 53b formed in the case 11 to be opposed to the windward side wall part 53a on a leeward side as compared with the platelike part 51. A radius of curvature of the platelike part 51 in a single body state is set to be larger than those of the windward side wall part 53a and the leeward side wall part 53b. In a state of the platelike part 51 arranged in the case 11, a moving direction intermediate part of the platelike part 51 abuts on the windward side wall part 53a, both the end parts of the moving direction of the platelike part 51 abut on the leeward side wall part 53b, and thereby the platelike part 51 is elastically deformed.
