Claims

[Claims for Utility Model Registration] 1. A plurality of braking pulleys that generate an appropriate holding torque are provided on a base that rotatably supports the display device main body in a horizontal plane, and a drive motor and this drive motor are provided on the display device main body side. 1. A horizontal rotation mechanism for a display device, characterized in that a drive pulley for transmitting rotational power is provided, and a belt is wound around a plurality of braking pulleys on the base side and a drive pulley on the drive motor side. 2. The belt according to claim 1, further comprising one or more guide rollers that contact the belt wound around the drive pulley and the brake pulley from the outside to form a bent part in the belt rotation locus. Display device horizontal rotation mechanism. 3. The horizontal rotation mechanism for a display device according to claim 2, wherein at least one of the guide rollers is provided to be elastically movable so as to apply appropriate tension to the belt. 4. The guide roller is fixed to the main body of the display device, and the drive pulley is provided on the main body of the display device so as to be elastically separable from the guide roller, so as to apply appropriate tension to the belt.
