ABSTRACT:
In a brake-equipped retracting mechanism, rotational force of a motor is used to open a liquid crystal display device from a retracted position to an open position, a power spring is wound up in conjunction with this opening operation, and elastic restoring force thereof is used to return the liquid crystal display device from the open position to the retracted position. A rope for developing a greater or smaller tensile force in conjunction with opening and closing of the liquid crystal display device is wound around a slip clutch linked to a reducer input shaft, whereby braking force for preventing the liquid crystal display device from an abrupt return is applied to the reducer input shaft. The braking force gradually decreases as the liquid crystal display device returns to the retracted position, and the liquid crystal display device can therefore be returned at a substantially constant speed.
