<p>PURPOSE: To simplify the manufacturing steps and to reduce the manufacturing cost by providing a shaft clamping plate fixing part for fixing a shaft clamping plate for holding a louver shaft when the louver is manually displaced and a motor base fixing part for fixing a motor base when the louver is driven by a motor at one end of a discharge frame for supporting the shaft. CONSTITUTION: A variable louver is provided at its shaft at one end, and air direction is changed by rotating the shaft or holding it at a predetermined position. In the case of automatic louver specification, a motor mounting base 43 is fixed to the one end 41a of a diffusing frame for holding the shaft of the variable louver, while in the case of manual louver specification, it is fixed to a shaft clamping plate 44. Thus, bosses 45a, 45b for a pair of shaft clamping plate and bosses 46a, 46b for fixing a pair of motor bases are formed at the one end 41a of the frame. Thus, the manufacture of a product is simplified in the case of the specifications, thereby reducing the manufacturing cost.</p> |
