PURPOSE: To lower manufacturing costs by providing a plurality of fins between left and right fin mounting frames being inserted and held through slits to eliminate the need for a welding means or a grinding means. CONSTITUTION: A suction port 12 and an air discharge port 13 are formed in a casing body 11 and a louver mechanism 14 is mounted on the air discharge port 13 to regulate the direction of air. Both fin mounting frames 15 each have an internal wall 18 and an external wall 19 bent at the right angle from both side rims in the direction vertical to a front wall 17. A mounting wall 20 is formed on the tip rim of the external wall 19 as bent at the right angle and a mounting screw insertion hole 21 is cut into the mounting wall 20. Slits 22 are arranged vertically in stages to hold a plurality of fins 16 on the internal wall 18 being inserted therethrough. A buffer sheet 23 is stuck on the internal surface of the external wall 19 to prevent impact with the end faces of the fins 16. |
