PROBLEM TO BE SOLVED: To reduce inclination of an ascending or descending grill at the time of its ascending operation and improve its outer appearance of a wire taking-up structure of an ascending or descending grill of an indoor device by eliminating a disturbance of taking-up volume of the wire in response to a location of several reels.SOLUTION: This invention comprises a filter for preventing dust from entering at an air suction port arranged at the central part of an ornamental panel; an ascending or descending grill having the filter fixed at the central part of the ornamental panel; a motor for the ascending or descending grill arranged at the ornamental panel near the ascending or descending grill; several reels attached to a shaft of the motor for the ascending or descending grill and rotated together with the shaft; and a wire for ascending or descending the ascending or descending grill while being wound up or released through rotation of the reel. The reel is constituted in such a way that a diameter part of its taking-up part is inclined and its diameter is increased as it faces from one terminal end toward the other terminal end, and the wire is taken up intensively in advance from a fine location of the taking-up part when the wire is taken up. |
