In addition, the bending of the connecting arm is suppressed by the third type vane connected to the connecting arm via the intermediate connecting shaft, and the inclination of the third type vane is held at a predetermined angle to obtain a desired wind direction changing action. is there.

As described above, according to the third aspect of the present invention, one pair of right and left sets are arranged at the outlets, respectively, and are rotationally displaced in mutually opposite directions to change the wind direction. And a plurality of dew receiving recesses are provided on the surface of the vane. As a result, a narrow gap is formed in the center where a pair of left and right vanes provided at the air outlets face each other, and the dew generated by the vanes that entrains the secondary air around it due to the weak wind blowing from this gap, Since it is retained in the dew receiving recess, it has the effect of preventing dew dripping.

Further, as described above, the invention according to claim 4 of the present invention is provided at the vane which is arranged at the outlet and is rotationally displaced to change the wind direction, and is provided at the one side edge portion of the vane. One side of the annular shape is cut out to form a C-shape, and a pivot bearing, a sleeve fitted to the pivot bearing in an embracing state, and an inner wall of the air outlet are erected upright and inserted into the sleeve. And a shaft provided with a claw engaging with the upper edge of the sleeve.

As a result, the vane provided at the outlet is pivotally attached to the shaft erected from the inner wall of the outlet through the sleeve and the pivot bearing. Therefore, there is an effect of smoothing the pivotal movement of the vane at the pivotal attachment point, and an effect of quieting the environment with less noise at the pivotal attachment point.
