In an air passage opening/closing device for an air conditioner, a slide door for opening and closing an opening portion of a case includes a flexible film member having a free top end that moves forward by pushing force in a door moving direction. A movement of the film member is guided along a guide ditch. The guide ditch is provided so that the film member is approached to a seal surface in a direction perpendicular to a door moving direction, in comparison with the other seal surface on a peripheral portion of the opening portion. For example, a pushing member for pushing the film member to the seal surface in the direction perpendicular to the door moving direction can be provided. Accordingly, air leakage due to a bending habit of the film member can be restricted.
