LOUVER STRUCTURE OF AIR CONDITIONER

PROBLEM TO BE SOLVED: To improve durability of right and left wind direction change devices.SOLUTION: An air outlet 5 is opened upward or rearward of a frame member, a louver frame 9 variably changing an air flow between an upward direction of the frame and a rearward direction of the frame is rotatably attached to the air outlet 5. The louver frame comprises: a lower louver of U-shaped section; and an upper louver substantially in parallel with the lower surface of the lower louver and spaced apart from it to cover an upper part, plural right and left air flow plates are arranged between the upper louver and the lower louver and rotatably arranged at the right and left sides, the right and left air flow plates are oppositely provided with a cylindrical lower shaft bearing part and a cylindrical upper shaft bearing part, and there are provided right and left air flow plates angle adjustment means constituted such that rotating shafts 17 of the right and left air flow plates are inserted into the shaft bearings, flat right and left air flow plates are rotatably arranged, the surface of the lower shaft bearing is formed with many grooves 19, the right and left air flow plates opposing against the grooves are provided with elastic protrusions 21, and when the right and left air flow plates are rotated, the protrusions ride over the grooves to cause the rotating positions of the right and left air flow plates to be set.
