Are connected by levers (not shown) and moved in the same direction at the same time. I am trying.

Therefore, in this conventional example, there is a drawback that the angle of the wind direction plate cannot be manually adjusted, and the motor must be turned on and off one by one even when a slight adjustment is required. In addition, adjusting the wind direction is equivalent to tilting the entire air outlet opening in a certain direction, so to speak,
Even the blowing width cannot be changed. That is, it is not possible to narrow the width of the blown air in a spot shape or widen the width of the blown air to perform so-called wide air blowing.

However, in order to realize this, as shown in FIG. 3, a plurality of wind direction plates 1 ... Can be divided into, for example, two groups 1L and 1R, and they can be moved in a direction facing each other or in a direction away from each other. Since this requires a motor as a drive source for each group, it is said that a large increase in cost is inevitable.

The present invention has been made in view of the above conventional circumstances, and its main purpose is to adjust the wind direction of an air conditioner in which each wind direction plate group can be rotated in the same direction or in the opposite direction by one motor. To provide a device.
