Drive gears 50 are attached to the fitting projections, and finish caps are fitted in the lower portions of the rotation screens 30. Drive gears 50 mounted on the fitting projections are arrayed in a row on the upper face of an upper frame 20. On both sides of the drive gears 50, there are individually arranged bearings 62 for applying tension to one gear belt to be meshed with the drive gears 50. On the upper frame 20, there is attached a lid body, to which a sensor is attached. By the actuation of a drive motor 63 on the basis of the sensed signal of a sensor, the one-side gear belt 60 rotates the drive gears 50 attached to the upper part of the rotation screens 30 at the same time in the same direction so that the rotation screens 30 are opened and closed in the same direction.</p> |
