As shown in FIG. 2, a boss 8a for supporting the first wind direction deflecting plate 6 and a boss 9a for supporting the second wind direction deflecting plate 7 are provided on both sides of the outlet 7. A support plate 5 protruding toward is provided. The first wind direction deflecting plate 6 is provided with a rib 6a on both sides of the upper surface, the shaft 6b protruding outward from the left and right. Similarly, the second wind direction deflecting plate 7 is also provided with a shaft 7b on both sides of the upper surface. A rib 7a protruding left and right is provided upright. The shaft 6b is attached to the boss 8a via a bush 10, and similarly, the shaft 7b is
To the boss 9a via

The bush 10 is made of a synthetic resin such as a polyester resin material having abrasion resistance.
As shown in (A), a flat base 10a formed in an inverted triangular shape, and a support shaft 10b protruding from the base 10a.
A shaft hole 10e corresponding to the shaft 6b of the first wind direction deflecting plate 6 is formed in the shaft portion 10b, and a plurality of slits 10c and a locking claw 10d are formed at the tip.
Are formed. Similarly, the bush 11 has a flat base 11a formed in an inverted triangle shape, and the base 11a.
And a support shaft 11b protruding from the support shaft 11b.
The support hole 1 corresponding to the shaft 7b of the first wind direction deflection plate 7
1e is drilled and a plurality of slits 1
1c and a locking claw 11d are formed. The support plate 5
