It has the following drawbacks. The drawbacks are shown in the order of the above-mentioned publications.Since the bushing is extended, a large amount of force is required for installation, and the range of inclination adjustment is not regulated. Although the pivot shaft of the wind direction changing plate is supported by being held between elastic claw pieces, axial wobbling is not prevented and the range of tilt adjustment is not restricted. The wind direction changing plate is connected by an interlocking rod, but the pivoting to the mounting frame utilizes elastic deformation of the wind direction changing plate and the mounting frame, making it difficult to install. The last publication does not require the wind direction changing plate to be modified and attached, but does require a separate support plate.

(c) Problems to be Solved by the Invention The present invention provides a wind direction changing device in which a wind direction changing plate can be easily attached to a mounting frame and has a simplified structure.

(d) Means for Solving the Problems The present invention includes a mounting frame having a pivot portion formed on the opposite side wall, and a wind direction changing plate having pivot shafts formed at both ends to be pivotally supported on the opposite side wall. A step is formed in the middle, and an insertion hole is formed in the side of the step to form a shaft support. The problem is solved by the first means of forming a protrusion.

Furthermore, the present invention includes a mounting frame with a pivot formed on the opposite side wall, and a wind direction changing plate having pivot shafts formed on both ends thereof, and the pivot shaft formed on the wind direction changing plate. The problem is solved by a third means of forming one side longer than the other and forming an elastic pressing plate that is suppressed and deformed at the end of the long pivot shaft on the pivot side portion where the long pivot shaft is inserted and pivotally supported. It is something.

In the above-mentioned first means, second means, and third means, the number of wind direction changing plates may be one or more than one, but when forming the wind direction changing plate with a plurality of sheets, This problem is solved by a fourth means in which the wind direction changing plates are connected by interlocking rods and can be tilted in conjunction with each other in the same direction.

It goes without saying that the present invention can solve the problem by implementing each of the above-mentioned means individually, but it is also natural that the problem can be solved by implementing the above-mentioned means at the same time, and these are within the scope of the present invention. It is.

(E) Effect In the first means of the present invention, the pivot shaft is formed in a stepped portion, and the pivot shaft can be pivoted easily and with a reduced degree of deformation by the elastic deformation of the wind direction changing plate, and the protrusion is formed on the step of the pivot shaft. The range of inclination is regulated at the opening to the section.

In addition to the same effect as the first means, the second means further improves operability, and the force applied to the protrusion is absorbed by the elasticity of the wind direction changing plate.

By using the third means, the long pivot shaft can be deeply inserted into the pivot support by deforming the elastic pressing plate, the short pivot shaft can be easily pivoted into the pivot support, and the wind direction changing plate can be pivoted. After the wind direction changing board is moved, it is urged in a direction that prevents it from coming off, providing stable support and preventing the wind direction changing board from wobbling.

The fourth means allows smooth operation of the plurality of wind direction changing plates.
