The second lock plate is moved by a certain amount and thereby returns the fan switching button or mode switching button that had been pressed down until then.

[Embodiments] Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the present invention, and in FIG. An automatic button 20, which is a feature of the present invention, is arranged, and as shown in FIG. When the automatic button 20 is pressed from a state where one of the buttons 12 is pressed and the wind direction mode is set, the pressed mode switching button 12 returns to its original state and switches to automatic control of the wind direction mode. It will be done.

Furthermore, when this automatic button 20 is pressed, the rotation speed of the fan can be switched to automatic control at the same time as the wind direction mode, and when one of the fan switching buttons 16 arranged below is pressed, that button is 16 is fixed in the pushed-in position and the fan is rotating at the rotation speed displayed on the button, and when the automatic button 20 is pressed to switch the fan rotation speed to automatic, the fan is in the pushed-in state described above. Fan switching button 16
needs to be returned to its original position.

For this purpose, a coupling mechanism as described below is provided.

That is, a lock plate 22 is disposed on the automatic button 20 via a cam mechanism (not shown), and this lock plate 22 moves the automatic button 20 in the direction of arrow A.
When pushing in the direction to change the wind direction mode to automatic control, it moves a predetermined amount in the direction of arrow B.

In addition, multiple fan switching buttons 16 are arranged on the lower side.
A lock plate 24 is disposed in the lock plate 24, and the lock plate 22 and the lock plate 24 described above are connected by a rotation link 26 having a fulcrum in the center.The lock plate 22 is moved in the direction of arrow B by pressing the automatic button 20. When the rotation link 26 is rotated in the direction of arrow C, the lock plate 24 is rotated.
