<P>PROBLEM TO BE SOLVED: To provide a plate door for an air-conditioner capable of reducing the ventilation resistance of a plate door. <P>SOLUTION: It is defined that the direction orthogonal to both the axis of a shaft part 31 of a plate door 3 and the air flow direction B is the passage height direction C. The shaft part 31 has a columnar end shaft part 311 supported by a case 1 and an intermediate shaft part 312 with a plate part 32 being coupled therewith and arranged in a passage 2. In the intermediate shaft part 312, the maximum dimension L of the passage 2 in the passage height direction C in a fully-opened state is smaller than the outside diameter of the end shaft part 311. Thus, the area of the intermediate shaft part 312 occupied in the passage area when the passage is fully opened is smaller than the conventional value, and the ventilation resistance is reduced thereby. <P>COPYRIGHT: (C)2009,JPO&INPIT |
