<p>PROBLEM TO BE SOLVED: To prevent condense from being produced between adjacent right and left air deflectors by providing a predetermined gap between both the ends of the adjacent deflectors when the ends of adjacent deflectors are rotated toward each other so as not to reduce ventilating air volume. SOLUTION: Gears 9a, 9b having teeth on opposed peripheries are mounted to supporting axes 6a of adjacent right and left air deflectors of a group of right and left air deflectors 6, respectively, and an intermediate gear 10 is rotatably provided in such a manner that when it is brought close to the apex of an equilateral triangle, in which a straight line interconnecting the supporting axes of the years 9a, 9b constitutes a base of the triangle, the gear 10 meshes with the gears 9a, 9b. And when the ends of one group of deflectors and rotated toward the ends of other group of deflectors, a gear of one group is caused to mesh with the gear 10 and when the end of the other group is rotated toward the end of one group, the gear of the other group meshes with the gear 10 to rotate the gear of one group, so that the end of the other group is brought toward the end of one group and the end of the one group is moved reversely with respect the end of the other group.</p> |
