The upper flap 12 is a plate-like member formed in a substantially L shape extending from the upper edge 9b to the upper end of the side edge 9a, and is a third
As shown in the figure and FIG. 5, they are connected via a ball joint (universal joint) 19.

That is, a connecting support 20 is fixed to the upper end of the baffle plate 11 with bolts 21, and a ball joint perpendicular to the width direction of the baffle plate 11 is provided at the center of the support body 20. A rod-shaped base end 19a of the int 19 is fixed. A locking protrusion 22 is provided on the outer periphery of the base end 19a of the ball joint 19.
is formed, and this locking protrusion 22 is attached to the support body 2.
The ball joint 19 is fixed to the support body 20 by fitting into a locking groove 23 formed in the ball joint 19 .

On the other hand, a pivot bearing 24 is buried in the lower end of the upper flap 12.
The spherical portion 19b of the ball joint 19 is fitted into the spherical seat 24a of No. 4.

As a result, the upper flap 12 is rotatable in all directions about the ball portion 19b of the ball joint 19.

The lower flap 13 is a generally parallelogram-shaped plate member extending from the lower end of the side edge 9a to approximately the center of the lower edge 9c, and has an upper end formed by the same means as the upper flap 12 described above. and is connected to the lower end of the baffle plate 11.

Furthermore, in the above-described hinge connection of the air guide plate 11 to the front cover 8 and the connection structure of the upper and lower flaps 12 and 13 to the air guide plate 11, the air guide plate 11 and the upper and lower flaps 12 and 13 can be manually operated. Appropriate friction is provided between each member to allow the rotation operation and to maintain the position after the operation.
