効果がある。According to the present invention, the conditioned air W to the room
Of the frame members 10 and 1 facing each other forming the edge of the air outlet 4
In an air conditioner equipped with a substantially rectangular plate-shaped wind direction adjusting blade 5 that is rotatably supported with respect to 1 via a support shaft 12,
A notch 7 is formed at the end of each of the wind direction adjusting blades 5 on the support shaft side, and a corner portion of which the angle with respect to the flow direction of the conditioned air W is an acute angle is cut into a triangular shape to form a notch 7 for cooling. When the angle of the wind direction adjusting blade 5 is changed to change the blowing direction of the cool air W into the room during operation,
The presence of the notch 7 formed at the end of the wind direction adjusting blade 5 on the support shaft side reduces the resistance to the flow of the blown cool air, so that the cool air with a relatively high wind speed is generated at the end of the wind direction adjusting blade 5 on the support shaft side. Since the air is blown out, the warm indoor air W 0 existing near the end of the wind direction adjusting blade 5 on the support shaft side is not sucked into the wind direction adjusting blade 5 side, and the dew condensation on the wind direction adjusting blade 5 does not occur. There is a practical effect that it can be prevented by an extremely simple configuration without deteriorating the design of No. 4.

Since the resistance to the flow of the blown-out cool air is reduced by the presence of the cutout portion 7 formed in the, the cool air having a relatively high wind speed is blown out at the end of the wind direction adjusting blade 5 on the spindle side, and the wind direction is adjusted. The warm indoor air W 0 existing near the end of the blade 5 is not sucked into the wind direction adjusting blade 5 side. Therefore, the dew condensation on the wind direction adjusting blade 5 is prevented by the extremely simple structure without impairing the design of the air outlet 4.
