<p><P>PROBLEM TO BE SOLVED: To provide an air passage opening/closing device capable of opening/closing two air passages by a compact and simple mechanism. <P>SOLUTION: Opening parts 31a-34a and passage blocking parts 31b-34c located on both sides of the opening parts are provided in a plurality of thin sheet members 31-34. The length of each opening part in the door moving direction (b) is different by a predetermined amount, and when the smaller thin sheet member of the adjacent ones is moved in the door moving direction (b) by the predetermined amount, the smaller thin sheet member and the larger thin sheet member adjacent thereto are moved together, the opening range of two air passages 11, 12 is determined by the moving position of the opening part 31a of the smallest thin sheet member 31 with the driving force applied thereto, and the blocking range of the two air passages 11, 12 is determined by laminating the passage blocking parts of the plurality of thin sheet members in a deviated manner stepwise. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
