<P>PROBLEM TO BE SOLVED: To provide a wind direction changing device, which standardizes a wind direction plate and components to facilitate assembly with a small number of components, and which eliminates the need for a wide space. <P>SOLUTION: A plurality of wind direction plates 50 including a blade part 51, a support part 53 provided on the end of the blade part 51, a rotating shaft 53a erected on the support part 53, and a link shaft 53b erected on the opposed face of the rotating shaft 53a are pivotally supported on a supply opening sidewall 20b with the rotating shaft 53a, and connected with a link plate 8 connecting the respective link shaft 53b. The rotating shaft of any one wind direction plate 50 and a driving shaft 61b of a motor 61 are coupled with a coupling shaft 62 having a hook 62c on the outer periphery. A spring 63 arranged so as to wrap the rotating shaft 53a and the coupling shaft 62 is locked on the supply opening sidewall 20b and the hook 62c, and when one wind direction plate 50 is rotated with the motor 61 by giving drive force, the other wind direction plate 50 is also followed and rotated to be the wind direction changing device 5. <P>COPYRIGHT: (C)2013,JPO&INPIT |
