A cylindrical support shaft portion 4b having a substantially rectangular locking hole 4c is rotatably supported, and a locking claw 4a is provided on the upper portion of an arm extending horizontally from the support shaft portion 4b. A stopper link 4 having a protruding stopper 4d at a lower portion, a motor rod 5 having a plurality of groove-shaped engaging portions 5a corresponding to the engaging claws 4a, and a support engaging with the engaging hole 4c. The wind direction plate 6 having the shaft 6a is connected to the air flow direction plate 6, and the connecting portion is composed of a louver rod 7 having a restricting piece 7a for restricting the rotation angle of the wind direction plate 6 in correspondence with the stopper 4d. It was

The wind direction plate 6 is reciprocally rotated by the driving force transmitted through the motor rod 5 and the stopper link 4, and at the same time, is connected by the louver rod 7 to have the same rotation angle. It was supposed to rotate in conjunction with all at once.

However, when the wind direction plate 6 is reciprocally rotated, especially at both sides of the outlet, the wind direction plate 6 is moved.
There is a problem that the gap between the main body casing and the main casing is narrowed and the amount of ventilation decreases, which causes dew condensation on the wind direction plate 6.

Although not shown, in the case where a plurality of cross flow fans are arranged in the air conditioner, the ventilation amount is reduced in the central portion of the air outlet corresponding to the position where the cross flow fans are close to each other. Therefore, there is a problem that dew condensation occurs on the wind direction plate 6.
