In each of the embodiments described above, the motor 21
And two wires 13, but the guide roller 20
May be arranged at the center of the suction grille 10 to form a single wire and a single motor. Further, for example, when the suction grille 10 is heavy or large, the wire 13, the rotating drum 12 for winding the wire 13, the motor 21, and the like may be provided in an arbitrary number by weight distribution of the suction grille 10.

The guide roller 20 attached to the suction grille 10 is made into a smooth pulley so that the suction grille 10 can be balanced by its own weight and kept horizontal with respect to the floor surface. No special equipment and control is required. Furthermore, since the fixed end of the wire 13 is not a movable part that performs the elevating operation, but is provided on the decorative panel 7, the probability of breakage can be reduced, which is a desirable structure from the viewpoint of safety.
