PURPOSE:To reduce the number of component parts and man-hours for assembling by a structure wherein an operating knob to operate the louver of the grill and a connecting element are integrally molded through a thin hinge. CONSTITUTION:The operating knob 21 and a chain ring 23 serving as the connecting element are integrally molded through the thin hinge 24. When the operating knob 21 is rotated directly about pivots 30 in the direction indicated by the arrow G, horizontal louvers 200-204 are rotated cooperatively, resulting in performing the vertical adjustment of wind direction B. Furthermore, the innermost side of the horizontal louver 200 is vertically moved together with the innermost side of the operating knob 21 so as to rotate a vertical louver 310 through the chain ring 23 and the chain ring 32 of the vertical louver 31 with rotating center at pivots 10 in the direction F, which intersects the direction G of movement of the horizontal louver 20, resulting in performing the horizontal adjustment of wind direction E. |
