PROBLEM TO BE SOLVED: To provide the mounting structure of a wind direction board which removes the damage at setup of the supporting shaft and the bearing of the wind direction board and also removes the abnormal sound caused by backlash. SOLUTION: For this mounting structure, a front panel 5 which has a blowout port at the right and a suction port at the left is arranged at the front of the main body, and supporting shafts 6a and 7a are arranged in opposition at the upper and lower walls 6 and 7, respectively, of a blowout port, and his structure axially supports turnably the wind direction board 8 having bearing 8a and 8b at both ends. In this case, cones are made at the tips of the supporting shafts 6a and 7a, and cone seats are made at the bearings 8a and 8b, and also the upper wall 6 of the blowout port is put in the U-shaped two-stage constitution of an outer plate 6e and an inner plate 6b connected ahead above and below, and a recess opening rearward is made, and also the supporting shaft 6a is projected under the inner plate 6b, and also a tubular boss is projected above the supporting shaft 6a, and it is supported freely of up and down motion, and a movable holder 6c linked to the inner plate 6b is provided, and a press means for pressing the supporting shaft 6a of the movable holder 6c against the bearing 8a is provided. |
